Description
The Edwards EST SIGA-CR is an intelligent analog addressable control relay module designed for use with Signature Series systems. It provides a single Form “C” dry relay contact for controlling external equipment such as door closers, fans, dampers, and similar devices.
The module communicates over the Signature data loop and uses electronic addressing assigned by the loop controller. All operational decisions are processed onboard by a microprocessor, improving system response time and reducing sensitivity to line noise. The SIGA-CR is factory-configured with Personality Code 8 and requires no field configuration.
This standard-mount version installs in North American 1-gang electrical boxes. A UIO plug-in version (SIGA-MCR) is also available for use with Signature UIO motherboards.
