Architectural and Engineering


The carbon monoxide alarm shall be CO303. It shall be powered by a 90-270VAC,50/ 60 Hz source. The temperature operating range shall be between -10°C and 50°C and the humidity operating range shall be 5%-95% relative humidity.

The CO sensor shall be of a fuel cell design and shall meet the sensitivity requirements of Underwriters Laboratories UL2034 Single and Multiple Station Carbon Monoxide Alarms.

The alarm shall include an integral plug that can be installed in any electrical outlet following the UL/NFPA/Manufacturer’s recommen dedguidelines. The unit shall have a green LED that will illuminate

continuously and indicate that the CO alarm is receiving power and the alarm circuit is functioning.

The alarm shall include a test/reset button. If pressed and released during normal operation, it shall electronically simulate the presence of CO and cause the unit to go into alarm. This sequence tests the unit’s electronics to ensure proper operation. If pressed during alarm mode, the unit will be silenced and will begin monitoring CO levels again.

In accordance with UL 2034, the CO sensor will not alarm to levels of CO below 30 ppm and will alarm in the following time range when exposed to the corresponding levels of CO.

70 ppm CO concentration 60 – 240 minutes

150 ppm CO concentration 10 – 50 minutes

400 ppm CO concentration 4 – 15 minutes

The alarm shall include a piezoelectric horn that is rated at 85 decibels at 10 feet. When the unit detects carbon monoxide, the alarm pattern will be four (4) short beeps – followed by five (5) seconds of silence – followed

by four (4) short beeps.

The unit shall include a 5-year manufacturer’s limited warranty
