The Edwards / EST SIGA-CR Control Relay Module provides a Form “C” dry relay contact to control external appliances such as door closers, fans, dampers etc. This device does not provide supervision of the state of the relay contact. Instead, the on-board microprocessor ensures that the relay is in the proper ON/OFF state. Upon command from the loop controller, the SIGA-CR relay activates the normally open or normally-closed contact. The Signature Series modules are compatible only with GE Security’s Signature Loop Controller.
