Mircom MIX-M500SA Relay Control Module M500SA Supervised Control Modules are intended for use in intelligent, twowire systems, where the individual address of each module is select ed using the built-in rotary decade switches. This module is used to switch an external power supply, which can be a DC power supply or an audio amplifier (up to 80 VRMS), to notification appliances. It also supervises the wiring to the connected loads and reports their status to the panel as NORMAL, OPEN, or SHORT CIRCUIT. The M500SA has two pairs of output termination points available for fault-tolerant wiring and a panel-controlled LED indicator. This module can be used to replace an M500CA module that has been configured for supervised wiring operation. Show more
