About our Indicator Panel, LCD, Acknowledge, 256-Zone, Stainless

Our vandal resistant emergency assistance alarm range offers tough, cost‑effective, BS 8300‑2 and document M compatible systems suitable for public use. We supply stand‑alone alarms, multiple alarm systems with remote monitoring and combined systems with disabled refuge EVCS, building alarms, etc. For larger and smarter sites, we offer networked solutions with optional BMS interfaces. Ideal for hospitals, railway stations, hotels, airports and other public spaces.

One or more LCD panels can be installed in central monitoring station(s) or control room(s) to attract the attention of system operators in the event of alarm activation. LCD indicator panels also have an alarm active output to drive additional devices, e.g. beacons, sounders or monitoring systems.

This alarm master station comprises a stainless steel faceplate fitted with a 16‑character LCD display, an integral sounder and acknowledge button. The faceplate is annotated in black with the word ACKNOWLEDGE. Alternative annotation is available on request. Panels are supplied with flush or surface mount steel back boxes, please specify when ordering.

The acknowledge function allows local or remote devices to 'acknowledge' and temporarily mute alarms, giving reassurance that help is on its way and making verbal communication easier. If the alarm has not been reset within two minutes the alarm is reactivated.

Remote indicator panels cannot usually be used to reset alarms. To ensure staff attendance, emergency assistance alarms can only be reset using the reset unit located in the toilet.
