Edwards SIGA-UM — Signature Series universal Class A/B module in a standard two-gang mount.
The SIGA-UM has no fixed function. The installer picks one of 15 personality codes, which the Signature loop controller downloads into the module during configuration, and that code decides whether it behaves as an input, an output or a relay. That is what universal buys: one catalog number covers both input and output duty.
- 15 selectable personality codes; consumes two module addresses
- Input: two Class B or one Class A initiating device circuit (codes 1–4, 9–12)
- Input: one Class A or B two-wire smoke detector circuit (codes 13, 14, 20, 21)
- Output: one Class A or B notification appliance circuit (codes 15, 16)
- Output: one Form C dry relay contact (code 8, SIGA-UM only)
- Contacts rated 2 A at 24 Vdc, 0.5 A at 120 Vac; speaker power 50 W at 25 V audio or 35 W at 70 V audio
- 15.2 to 19.95 Vdc; end-of-line 47 kΩ for IDC/NAC codes, 15 kΩ for two-wire smoke
Universal stops at fire duty: none of the 15 codes is a security personality, and Edwards sends security circuits to the SIGA-SEC2 instead. Do not substitute the SIGA-MAB either, which is the plug-in UIO version with 14 codes and no Form C relay option.
