Automatic Sliding Door Product

Overview

An automatic sliding door is a powered pedestrian entrance in which two glass leaves slide apart on the approach of a person and close again once the threshold is clear. The complete unit hangs from a header beam mounted above the opening; nothing touches the floor except a guide channel. It is the standard entrance for retail, healthcare, hospitality and office buildings because it is hands-free, weather-sealing and high-traffic rated.

The system is built around the Operator Header Beam, an extruded aluminium beam that spans the opening and houses every working part behind a removable cover. Inside it sit the drive, the running track and the controller.

How it works

Motion is produced by the Belt Drive Unit. A brushless DC motor turns a toothed pulley through a single-stage reduction gearbox; the pulley drives a timing belt that loops the length of the header to a spring-loaded idler tensioner at the far end. Each glass Door Panel (Leaf) hangs from an Door Hanger Carriage, a trolley whose nylon roller wheels run along the Track & Guide Rail and whose belt clamp couples it to one run of the belt, so the two leaves part and meet symmetrically.

The Door Controller runs the motion profile, ramping speed up and down so the leaves accelerate smoothly and decelerate before the end stops. It takes its triggers from the Sensor Set: overhead microwave heads detect an approaching pedestrian and command an opening, while active-infrared presence curtains hold the door open as long as anyone occupies the threshold, preventing the leaves from closing on a person.

When the building is secured, the Electric Lock throws a solenoid bolt into a strike at the meeting stile. The fail-safe lock releases on power loss so the door can never trap occupants. To keep the door operable during an outage, the Battery Backup Unit holds a charged 18650 pack and a failover board that either drives the door fully open or maintains the locked state, according to the programmed mode.', },

A garage door opener is the ceiling-mounted machine that raises and lowers a sectional or one-piece garage door and holds it shut between cycles. This is a belt-drive smart opener: a quiet toothed belt moves the door, and a Wi-Fi link lets the door be operated and monitored from a phone. The opener does not carry the door's weight — that is the job of the door's own counterbalance springs — it only supplies the force to start and stop the panel and to hold it closed.

How it works

Power comes from the Power Head, a permanent-magnet DC motor feeding a worm-gear reduction box that turns a drive sprocket. The sprocket drives the belt inside the Rail & Trolley: a steel C-channel rail carrying the belt loop, a spring-loaded tensioner at the door end, and a travelling trolley that clamps to the belt and pushes or pulls a curved arm linked to the top of the door. A red manual-release cord disconnects the trolley from the belt so the door can be worked by hand.

The Control Board is the brain. Its microcontroller sequences the motor-direction relays, reads the travel encoder to learn the open and close limits, and hosts both a Wi-Fi Module for the app and an RF receiver that decodes rolling-code remotes and the entry keypad. Commands also arrive from the Wall Console inside the garage.

Safety is mandatory and redundant. The Safety Sensor System places an infrared photo-eye beam across the door near the floor; if the beam breaks while the door is closing, the opener reverses. A force-sensing module independently watches motor current and stops the door if it meets an obstruction. Handheld Handheld Remote units and the Wireless Keypad provide keyless entry, while the Battery Backup Module lets the opener complete cycles during a power cut.', },

A video intercom system lets a resident see, speak with and admit a visitor at a building entrance without going to the door. The visitor presses a call button at the entrance; an indoor monitor rings, shows live video of the caller, and a single touch releases the door lock. It is the standard access-control front end for apartment blocks, offices and gated houses.

How it works

At the entrance is the Door Station, a weatherproof flush panel built into an IP54 die-cast housing behind a vandal-resistant faceplate. It carries a wide-angle Entrance Camera Module with infrared illumination for night-time caller identification, a Call Button & Keypad Panel of apartment call buttons and a backlit PIN keypad, and an RFID Reader for keyless entry by credential holders. A door-station main board runs the SIP / 2-wire stack, encodes the video, manages echo-cancelled audio and holds the access logic.

Calls are answered at the Indoor Monitor. Each wall-mounted unit pairs a colour touchscreen with a controller that decodes the door-station video off the bus, drives the display and runs the duplex intercom audio; talk and unlock are single-button actions. The system ships with two monitors so a call rings at more than one point.

Power and data are split out by the Power & Bus Distributor, a DIN-rail board that feeds the door station and each monitor over the Bus / Network Wiring riser with a resettable fuse on every branch. When a resident grants entry, the door-station relay drives the Electric Door Release, a fail-secure electric strike mortised into the frame that holds the door shut on power loss and releases only when energised. Because the bus and power lines run outdoors, an in-line surge protector clamps lightning and switching transients before they reach the electronics.', },

'motorized-blinds': { specs: [ ['Type', 'Smart roller blind, in-tube tubular motor'], ['Drive', 'BLDC motor with planetary gearbox'], ['Roller tube', 'Extruded aluminium, keyway groove'], ['Fabric', 'Light-filtering or blackout roller fabric'], ['Connectivity', 'Wi-Fi + Zigbee + BLE'], ['Control', 'App, smart-home hub, RF remote, schedules'], ['Position sensing', 'Hall-effect encoder, programmable limits'], ['Power', 'Rechargeable Li-ion, 4 × 18650'], ['Charging', 'USB-C, optional solar trickle charge'], ['Solar panel', 'Monocrystalline, window suction mount'], ['Remote', 'RF handheld, multi-channel, CR2032'], ['Noise', 'Quiet operation, <38 dB typical'], ], body: '## Overview

Motorized blinds are roller shades that raise, lower and hold position under motor power instead of a pull chain. The shade fabric winds onto an aluminium tube driven from inside by a slim tubular motor, so there is no visible operator, cord or wand. Control is wireless — phone app, smart-home hub, schedule or handheld remote — which makes the product attractive both for convenience and for cord-free child safety.

How it works

The fabric winds on the Headrail Assembly, an extruded aluminium roller tube capped and bearing-supported at each end. Concealed inside the tube is the Tubular Motor: a brushless DC motor and planetary reduction gearbox whose output drives an adapter that grips the tube wall, so the whole tube rotates while the motor body is held still by a keyed crown.

Motion is commanded by the Control Board. Its microcontroller drives the motor through an H-bridge, reads a Hall-effect encoder to track travel and enforce the programmed upper and lower limits, and carries a combo radio that speaks Wi-Fi, Zigbee and BLE to apps and hubs. The blind hangs the Shade Assembly — the roller fabric with a weighted hem bar that keeps it flat and square — and runs from the Battery Pack, a protected 18650 Li-ion pack recharged over USB-C.

A Solar Charging Panel is offered as an option: a small monocrystalline PV cell on a window suction mount trickle-charges the pack in daylight, so a well-lit blind rarely needs manual charging. Day-to-day, the RF Remote gives up, down, stop and preset control on multiple channels, and the Bracket Set clips the tube end caps to the wall or window frame.', },

'roller-shutter': { specs: [ ['Type', 'Motorized roller shutter'], ['Curtain', 'Roll-formed interlocking aluminium/steel slats'], ['Drive', 'In-tube tubular AC motor'], ['Motor type', 'Single-phase induction, planetary gearbox'], ['Brake', 'Electromagnetic spring holding brake'], ['Limits', 'Mechanical gear-counter end-of-travel cams'], ['Roller tube', 'Octagonal steel/aluminium barrel'], ['Guides', 'Side U-channels with brush seals'], ['Enclosure', 'Sheet-metal headbox with inspection cover'], ['Control', 'RF receiver board, wall switch + remote'], ['Supply', '230 V AC single-phase'], ['Manual override', 'Hand crank + counterbalance spring'], ], body: '## Overview

A motorized roller shutter is a slatted curtain that winds up onto a barrel inside a box above a window or door opening and unrolls down side rails to cover it. Shutters provide security, weather protection, insulation and blackout, and are common on shopfronts, garages and residential windows. The slat curtain rolls compactly into a headbox, so the shutter clears the opening entirely when raised.

How it works

The barrier is the Shutter Curtain, dozens of roll-formed slats hooked together, fitted with end locks that keep the curtain captive in the rails, a hanger top slat, and a reinforced bottom rail that seals against the sill. The curtain winds onto the Roller Tube, an octagonal barrel carried on a driven end and an idler-end bearing.

Power comes from the Tubular Motor housed inside the barrel. A single-phase induction motor drives a multi-stage planetary gearbox; an electromagnetic spring brake holds the curtain at any height, and a gear-counter limit mechanism stops travel at preset top and bottom positions. The motor head reacts torque into the headbox end plate while a crown adapter keys the gearbox output to the tube.

The curtain edges run in the Guide Rail channels, lined with brush seals that cut noise and draughts, and the rolled-up curtain is concealed in the Headbox. Operation is wireless: the Control System uses an RF receiver board with up and down relays, fed by a wall switch and a handheld remote. For power failures, the Manual Override provides a hand crank and counterbalance spring so the shutter can be wound open by hand.', },

'sectional-garage-door': { specs: [ ['Type', 'Insulated overhead sectional garage door'], ['Sections', '4 hinged panels forming the curtain'], ['Panel construction', 'Twin steel skins, foamed PU core'], ['Insulation', 'CFC-free polyurethane, foamed in place'], ['Travel path', 'Vertical → curved → horizontal track'], ['Rollers', 'Sealed-bearing nylon on steel stems'], ['Counterbalance', 'Torsion spring, shaft, drums and cables'], ['Lift cables', 'Galvanized aircraft cable'], ['Sealing', 'Bottom astragal + perimeter jamb seals'], ['Locking', 'Manual slide-bar lock and handle'], ['Reinforcement', 'U-channel struts on top/operator sections'], ['Glazing', 'Optional double-pane window lites'], ], body: '## Overview

A sectional garage door is the most common overhead garage door: a curtain of horizontal panels hinged together that rolls from vertical, closed over the opening, up through a quarter-turn to horizontal storage along the garage ceiling. Because the panels articulate, the door takes up no swing space outside or inside the opening. This is an insulated door — steel-skinned panels with a foam core — for thermal performance and rigidity.

Construction

The curtain is four Door Panel Section sections, each two roll-formed steel skins sandwiching a foamed-in-place polyurethane core, capped by end stiles. The sections flex relative to one another at the Hinge Set: intermediate centre hinges at each joint and numbered end hinges that also carry the roller stems. Those stems hold the Roller Set, sealed-bearing nylon rollers that ride inside the Track Assembly — vertical track up each jamb, a curved radius section, and horizontal track suspended from the structure.

The door's weight is offset by the Counterbalance Assembly. A wound torsion spring on a shaft above the header stores energy as the door lowers; grooved cable drums on the shaft wind galvanized lift cables that run down to the bottom corner brackets, so the spring all but cancels the door's weight and the door can be lifted with one hand or a modestly sized opener.

Weather sealing comes from a flexible bottom astragal and perimeter Jamb Seal flaps, and tongue-and-groove strips between sections. A manual slide-bar lock secures the closed door, and U-channel reinforcing struts stiffen the top and operator sections against wind load and the pull of a powered opener.', },

'smart-door-lock': { specs: [ ['Type', 'Motorized smart deadbolt'], ['Bolt', 'Single-throw spring-loaded deadbolt'], ['Drive', 'DC gearmotor with slip clutch'], ['Entry methods', 'Keypad, fingerprint, RFID/NFC, app, key'], ['Keypad', 'Capacitive touch glass overlay'], ['Fingerprint', 'Capacitive sensor die'], ['RFID', '13.56 MHz NFC reader'], ['Connectivity', 'Wi-Fi / Zigbee / BLE'], ['Sensing', 'Magnetic bolt position + reed door sensor'], ['Mechanical override', 'Pin-tumbler key cylinder'], ['Power', '4 × 18650 Li-ion, removable tray'], ['Interface', 'Two-escutcheon, ribbon interconnect'], ], body: '## Overview

A smart door lock is a motorized deadbolt that can be locked and unlocked by code, fingerprint, card, phone or mechanical key, and that reports its state to a home network. It replaces a conventional deadbolt in the same door prep, with an exterior module holding the credentials and an interior module holding the motor and electronics. The appeal is keyless entry, remote control and an audit trail of who entered when.

How it works

Credentials are read at the Exterior Escutcheon escutcheon, a weather-sealed outside module carrying a capacitive PIN keypad, a fingerprint sensor, an RFID/NFC reader and status indicators, plus a pin-tumbler Key Override Cylinder for a mechanical key as a last-resort backup. The Interior Escutcheon escutcheon, mounted inside, contains a manual thumbturn, the drive motor, the main control board and the wireless radio.

When a valid credential is presented, the Main Control Board commands the Bolt Drive Motor — a small DC gearmotor — through a Drive Gearbox fitted with a slip clutch that protects the train if the bolt jams or is forced. The gearbox turns a cam and tailpiece that throw the Deadbolt Mechanism, a spring-loaded bolt whose position is read magnetically so the lock always knows whether it is thrown. A reed switch tracks whether the door itself is open or closed.

Connectivity is provided by the Wireless Radio Module, a Wi-Fi/Zigbee/BLE radio that lets the lock be operated and monitored from an app or smart-home hub. Everything runs from the Battery Compartment, a removable tray of 18650 cells, and the two escutcheons are tied together by a ribbon harness through the door.', },

A video doorbell is a doorbell with a camera, microphone and speaker that streams live video to a phone when someone presses it or walks up. The owner can see and talk to a visitor from anywhere, and the device records clips when it detects motion. It mounts where an ordinary doorbell would and can run on its own battery or splice into an existing doorbell transformer.

How it works

Imaging is handled by the Camera Module, an HD CMOS sensor behind a wide-angle lens with a switchable IR-cut filter for day/night operation. Compute lives on the Mainboard: a vision SoC paired with a housekeeping MCU, firmware flash, and a combo Wi-Fi/BLE radio with antenna that streams video and connects the device to the home network and app.

Detection comes from two sensor blocks. The PIR Motion Sensor uses a pyroelectric passive-infrared element behind a Fresnel lens to wake the camera on motion, and the Night-Vision Board board switches on infrared illuminator LEDs once its ambient light sensor reads darkness. Conversation runs through the Audio Subsystem subsystem — a MEMS microphone, a speaker and a Class-D amplifier for full two-way talk. A press on the Doorbell Button trips a tactile switch and lights the RGB status ring.

The doorbell is powered by the Battery Pack, a rechargeable Li-ion pack with a protection board, and can also draw from the Power Input Module module, which rectifies and regulates an existing 8–24 V doorbell transformer feed so the battery stays topped up. A separate Plug-In Chime plugs into a wall outlet and rings on press, and the whole unit fixes to the door frame on a bracket with an angle wedge and tamper-resistant screws.
