Manual Call Point
System Sensor MCP5A Manual Call-Points are designed to provide a manual interface for raising an Alarm on the Fire Alarm System. The MCP5A is a dedicated addressable Call-Point for installation on a two-wire communication circuit providing an Alarm signal to both the Fire Alarm Panel and local LED indication of activation. Manufactured by System Sensor, reliability is assured with a three year warranty from date of manufacture. A micro-switch is held in the OFF position by the breakglass. On pushing the glass, it fractures safely, due to a protective plastic coating, then drops down to release the switch. Internal electronics immediately notify the Control Panel of the activation and the Control Panel responds by turning on the integral Alarm LED for visual acknowledgement. With the MCP5A addressable capability, each Call-Point address is easily set with rotary decade address switches, giving the precise location of each Call-Point in the event of manual activation.
