Edwards SIGA-DTS — Signature Series duct test station: a key switch with an integral intelligent input module on a two-gang plate, supplied with two keys.
Duct detectors sit on ductwork, out of reach above a ceiling. Turning this key to TEST lights the station LED and makes the integral module report a duct detector test alarm, so the damper and smoke control sequences programmed at the panel are exercised too. Resetting the panel clears the test, and the key cannot be withdrawn in the TEST position.
- Standby current 250 µA; activated 400 µA
- 15.2 to 19.95 Vdc, 19 Vdc nominal
- Occupies one module address on the Signature loop
- Relay bases are not automatically operated; the panel may be programmed to do so
- Mounts to a 2 in. deep two-gang or 4 in. square box, ordered separately
- White engineered plastic front plate; replacement key P-037449
Edwards documents it only with the SIGA-SDH and SIGA-SDHR housings. SuperDuct and Optica duct detectors take one-gang stations instead, SD-TRK keyed or SD-TRM magnetic. SIGA-LED is a remote alarm indicator with no test function.
