1.4 SYSTEM OPERATION:
A. Furnish and install carbon monoxide detectors as shown on the project drawings. The detectors shall be monitored by interface devices on the fire alarm addressable loop and shall indicate the location of the carbon monoxide detector and shall clearly indicate the nature of the alarm as being carbon monoxide detection. Upon an alarm from a carbon monoxide detector an alarm shall be sounded on the dedicated carbon monoxide signal circuits and shall sound bells as the audible alarm. The bells shall be provided with engraved labels with not less than 1 inch letters indicating Carbon Monoxide Alarm. The alarm shall be different and distinct from the fire alarm audible and visible devices.
PART 2 PRODUCTS
2.1 SYSTEM:

alarm relay for interface to fire alarm addressable loop. The unit shall operate on 24VDC power and shall be suitable for flush or surface mount. All units shall be individually calibrated. The detectors shall be listed to UL standard 2075 and shall be tested to the UL standard 2034 for sensitivity requirements. The detector shall alarm at multiple levels of exposure to carbon monoxide based on time-weighted averages of the gas present. The detectors shall mount to a single gang box and shall be provided with the following operation indicators.
Green LED indicating normal operation
Amber LED indicating trouble with the device.
Red LED indicating Carbon Monoxide has been detected.
B. POWER SUPPLY/BATTERY BACKUP shall be provided from the Fire Alarm
