Other Accessory
Beyond readers, controllers and locks, a complete access-controlled door often needs safety and wiring accessories. BSD Infotech supplies emergency break glass units, sirens, door loops, relay output modules and wireless door bells for access control projects.
Accessories and Their Use
Emergency break glass
Lets people release a locked door in an emergency by breaking or pressing the unit, which cuts power to the lock.
Siren
Sounds an alarm on events such as a forced door or tamper, when connected to the controller’s alarm output.
Door loop
An armoured flexible conduit that protects the cable running from the frame to the door, for example to an electric lock on the door leaf.
Relay output module
Adds relay outputs to a controller so it can switch extra locks, sirens or other devices.
Wireless door bell
Lets visitors call reception or staff at a controlled door.
Plan the Whole Door
A typical controlled door combines a reader, controller, electric lock, exit button, power supply with backup, emergency break glass and a door loop. BSD Infotech plans the full set for each door.
