Edwards SIGA-MCR — Signature Series addressable control relay module, UIO plug-in.
The SIGA-MCR gives the loop controller one Form C dry contact for equipment outside the fire alarm system: door holders, fan starters, dampers. It does not supervise what it controls; an on-board microprocessor confirms the relay is in the commanded state. The UIO format suits cabinets holding several modules, since field wiring lands on the motherboard, not on each module.
- Form C dry contact, 2.0 A @ 24 VDC pilot duty, 0.5 A @ 120 VAC
- 15.2 to 19.95 VDC from the loop; 100 µA standby and active
- One module address; Personality Code 8, factory set
- Plugs into SIGA-UIO2R, UIO6R or UIO6 motherboards
- 32° to 120°F, 0 to 93% RH; green LED polled, red active
It will not mount on its own; order a UIO motherboard with it. For one relay at a remote point use the SIGA-CR, the same circuit in a 1-gang mount. The SIGA-CC1 is different again: it switches an external riser into a supervised signal circuit, not a dry contact.
