Gentex CR, catalog number 918-0036-002 — a 120 VAC single or multiple station electrochemical carbon monoxide alarm with an auxiliary relay.
This is a self contained dwelling unit alarm certified to ANSI/UL 2034, not a system CO detector on a signaling line circuit. It sounds its own horn, holds a 9V cell for backup, and its relay lets a CO condition drive a remote function. DUALINK tandem interconnect ties it to other Gentex alarms so every unit sounds.
- C Series certification is ANSI/UL 2034 only; the S and SC Series carry UL 217
- 120 VAC, 60 Hz, 0.055 A; backup is one Duracell MN 1604 9V alkaline
- Auxiliary relay of one Form A and one Form C, stated for CR, SR, SCR and SR220
- Temporal 4 audible pattern, the carbon monoxide pattern
- Operating ambient 40 to 100 °F; certified for wall or ceiling mounting
- 5.5 × 5.5 in. overall, 1.75 in. deep
- 10 year end of life indicator and low battery indicator
The plain C (918-0030-002) is this alarm without the relay. Do not confuse it with SC, SCR and SCRR, which add photoelectric smoke sensing, or the heat only H. Gentex states the S/C/SC/H Series replaces the CO1209, S1209 and GN-503 Series, in which CO1209F was the relay model.
