Reset units are used to reset activated disabled toilets alarms. These units are usually mounted on the wall inside toilet to try to ensure that an operator visits the location in response to an alarm. Reset units are fitted with vandal resistant reset buttons. The reset button must be held for a minimum of 0.25 seconds to reduce the risk of accidental alarm reset. The standard unit is annotated in black with the word RESET, alternative annotation is available on request. These units can be mounted in single gang 35mm flush or surface mount back boxes (not supplied).
