The beacon sounder reset unit combines the functions of alarm beacon, alarm sounder and reset point into a single unit. These units are usually installed outside a toilet to attract attention in the event of an alarm and allow access to reset alarms. Unit are usually supplied with a vandal resistant reset button but can be supplied with a keyed reset switch to prevent reset by unauthorised persons. The reset button/switch must be held for at least 0.25 seconds to reduce the risk of an accidental alarm reset. Standard units are annotated in black with the words ASSISTANCE REQUIRED RESET, alternative annotation is available on request. The unit can be mounted in a double gang 35mm flush or surface mount back box (not supplied).
