The Edwards SIGA-CRR Polarity Reversal Relay Module is a Signature Series intelligent addressable output module. Specifically, its 24 VDC output reverses polarity on command from the loop controller. As a result, this drives a group of SIGA-AB4G Audible Sounder Bases on the data loop.
Importantly, the “polarity reversal” in this module’s name refers to the audible-base power circuit. Therefore, it is not a city-tie or municipal reverse-polarity reporting module. Instead, technicians use it strictly within Signature Series notification design.
Loop function
- Signature Series output module with factory-set Personality Code 8.
- Uses one module address on the SLC.
- LEDs: green flashes when polled; red illuminates when active.
Verified electrical specs
- Operating voltage: 15.2 to 19.95 VDC (19 VDC nominal) supplied by the loop controller.
- Standby current: 100 µA.
- Activated current: 100 µA.
- Relay: Form “C” dry contact.
- Contact rating: 2 A @ 24 VDC (pilot duty), 0.5 A @ 120 VAC.
Mounting
The SIGA-CRR mounts to a North American 2 1/2″ deep 1-gang box. Alternatively, install it in a 1 1/2″ deep 4″ square box with a 1-gang cover plus the SIGA-MP plate adapter.
- Construction: high-impact engineering polymer.
- Operating temperature: 32 to 120 °F.
- Humidity: 0 to 93% RH, non-condensing.
- Ship weight: 0.4 lb.
Panel compatibility
The SIGA-CRR works with Edwards Signature Loop Controllers in the EST3, EST3X, iO Series, and EST4 panel families.
Agency listings
