SYSTEM SENSOR CO1224T 12/24V CO Detector with RealTest Technology – Wall or Ceiling Mount

Overview

The SYSTEM SENSOR CO1224T is a compact 12/24 VDC carbon monoxide detector designed for reliable integration with modern security and fire alarm panels. It uses an electrochemical sensing cell to provide accurate CO monitoring and includes a code-required trouble relay to communicate sensor status or end‑of‑life signals to the control panel and central station.

Equipped with RealTest Technology, this detector supports a quick, functional check by simulating CO exposure with a canned CO spray. When performed as instructed, the unit can beep to confirm the gas entry is detected, giving installers confidence in proper operation without external test vents or devices.

Key benefits and features

• RealTest enables a functional test using canned CO gas, helping verify alarm response quickly and safely.
• Code-required trouble relay provides status updates to the control panel and central station, supporting monitoring and maintenance workflows.
• Wiring supervision with SEMS terminals ensures robust connections during installation and over time.
• Powered by 12/24 VDC, offering broad compatibility with a wide range of systems.
• Low standby current minimizes load on the overall system while maintaining readiness.
• Versatile mounting supports both wall and ceiling installations for flexible placement.
• Electrochemical sensing delivers accurate CO detection with fast response characteristics.
• 10-year end‑of‑life timer helps plan replacement and routine maintenance.

Practical use and installation notes

Ideal for homes, apartments, and small facilities, the CO1224T integrates with central monitoring to provide around‑the‑clock visibility of CO conditions. The 85 dB alarm is designed to attract attention in busy environments, while the device remains compact enough for tight spaces.

• Operating temperature range from 32°F to 104°F and humidity tolerance from 22% to 90% RH support a variety of indoor environments.
• Compact dimensions (3.3 W x 1.3 H x 5.1 L inches) and a weight of about 7 oz simplify installation and placement.
• Supports 14–22 AWG input wiring for flexible wiring options.
