Gamewell-FCI MCS-CO3 — intelligent addressable carbon monoxide detector, certified to UL 2075 for system-connected life safety CO monitoring.
Commercial CO codes increasingly require detection where fuel-burning equipment runs, and this puts it on the fire system addressable loop. The address is set on rotary switches, so the panel names the exact point, not a zone. It senses CO only, with drift compensation and RealTest testing.
- Velociti protocol, one address, rotary address switches
- 15 to 32 VDC; 200 µA operating, 2 mA alarm, 4.5 mA maximum at 24 VDC
- 10-year CO cell with end-of-life warning and fault
- UL 2034 response: 70 ppm in 60–240 min., 150 ppm in 10–50, 400 ppm in 4–15
- 32 °F to 122 °F, 15% to 90% RH; isolator load rating 0.0063
- E3 Series 4.10, S3 Series 1.21 or NGA 4.01 firmware and higher; UL S1195
Not to be confused with MCS-COF3, the multi-criteria fire/CO detector that adds smoke, infrared and thermal sensing on one address and is rated only to 100 °F. It is a plug-in head; its data sheet lists bases as separate order codes, and a B200S sounder base produces the Temp 4 CO pattern.
