System Sensor CO1224TR 4-Wire CO Detector with Form C Relay

4-wire CO detector with Form C relay for fire alarm integration

• 24VDC 4-wire design integrates directly into conventional or addressable fire alarm panels.
• Form C relay output enables dry-contact alarm signaling without intermediate interface modules.
• 10-year end-of-life timer and RealTest capability reduce commissioning and maintenance overhead.

System Sensor · COSMO-4W

System Sensor COSMO-4W 4-Wire Combination CO/Smoke Detector with Sounder

4-wire combo CO/smoke detector with built-in sounder for conventional panels

• Combines CO and ionization smoke detection in one unit, reducing loop device count.
• Built-in sounder eliminates separate notification appliance wiring at each install point.
• 35VDC 4-wire design integrates directly with conventional fire alarm control panels.

System Sensor · COSMO-2W

System Sensor COSMO-2W i4 Series 2-Wire CO/Smoke Detector with Sounder

Dual smoke/CO detector on single 2-wire loop with integrated sounder

• Photoelectric smoke and electrochemical CO sensing share one 2-wire loop address.
• Integrated sounder eliminates external horn modules, reducing device count per zone.
• Mounts to 3.5"/4" octagonal, single-gang, 4" square, or round ceiling boxes.
