This type of system is designed primarily to summon help. In its simplest form this could be a pull cord activating a sounder and a flashing light for persons in distress using a disabled toilet facility.
Call systems can be designed to operate from a push button, a hand held transmitter, a pressure mat, a motion sensor, or specialised equipment for the disabled. When operated, call systems can be designed to activate a control unit, indicate on a display unit, activate an over-door flashing light, alert by an audible tone, or activate a paging system.
Hi-performance systems can report by PC to produce operational statistics, and may be hard-wired or wire-free installations.
An intelligent call system can become a staff attack system, signalling help required or an emergency. Activating from a personal trigger, these systems can report the location of the member of staff needing assistance, and the urgency of help required.
Micro Alarms have installed systems in hospitals, care homes, prisons, secure mental health units, shopping centres, and many more.
