The Edwards EST SIGA-CR is an intelligent addressable control relay module from the Signature Series. It provides a single Form-C dry-contact relay output that can be controlled by the fire alarm control panel over the Signature Series addressable loop — enabling supervised control of auxiliary equipment such as elevator recall, HVAC shutdown, door holders, damper actuators, and other building systems that require fire alarm integration.
Because the SIGA-CR is individually addressable, the panel can activate or deactivate its relay independently, and the module continuously reports its supervisory status back to the FACP. This eliminates wiring failures going undetected and ensures the relay is operational when needed.

Overview
The Control Relay Module and the Polarity Reversal Relay Module are part of the Signature Series system. They are intelligent analog addressable devices available in either plug-in (UIO) versions, or standard 1-gang mount versions.
The SIGA-CR/MCR 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/MCR relay activates the normally open or normally-closed contact.
Features
- Provides one no/nc contact (SIGA-CR/MCR): Form “C” dry relay contact can be used to control external appliances such as door closers, fans, dampers etc.
- Allows group operation of sounder bases: The SIGA-CRR/MCRR reverses the polarity of its 24 Vdc output, thus activating all Sounder Bases on the data loop.
- Plug-in (uIO) or standard 1-gang mount: UIO versions allow quick installation where multiple modules are required. The 1-gang mount version is ideal for remote locations that require a single module.
- Automatic device mapping: Signature modules transmit information to the loop controller regarding their circuit locations with respect to other Signature devices on the wire loop.
- Electronic addressing: Programmable addresses are downloaded from the loop controller, a PC, or the SIGA-PRO Signature Program/Service Tool; there are no switches or dials to set.
- Intelligent device with microprocessor: All decisions are made at the module to allow lower communication speed with substantially improved control panel response time and less sensitivity to line noise and loop wiring properties; twisted or shielded wire is not required.
- Ground fault detection by address: Detects ground faults right down to the device level.
