BRK electronic CO5120PDB user manual Co Alarm Specifications

CO ALARM SPECIFICATIONS

Gas Detection at Typical Temperature and Humidity Ranges: The CO Alarm is not formulated to detect CO levels below 30 ppm typically. UL tested for false alarm resistance to Methane (500 ppm), Butane (300 ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol (200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and vapor concentrations in parts per million.

Required Alarm Levels: Before 10% COHb exposure at levels of 30% to 70% Relative Humidity (RH):

•400 ppm CO between 4 and 15 minutes

•150 ppm CO between 10 and 50 minutes

•70 ppm CO between 60 and 240 minutes

When exposed to a constant level of 30 ppm of CO, this CO Alarm was tested not to go into alarm for at least 30 days.

Audible Alarm: 85dB minimum at 10 feet.

Power: Powered by 120VAC. The 9V battery back-up provides 8 hours of standby and sounds alarm for 12 hours with fresh battery. When AC power is on, red light (LED) shines continuously. Under battery power, red light flashes once a minute.

Malfunction: Horn chirps and light blinks 3 times (in rapid succession) every minute and digital display shows “Err”.

Dimensions: 5.4” diameter (approx.)

Supply Voltage: 120VAC 60Hz, 0.09A.

During Alarm: Repeating alarm horn pattern:

4 beeps, pause, 4 beeps, pause.

•Stand-alone unit: red light (LED) flashes once per second.

•Interconnected series: red light (LED) flashes once per second on the Initiating alarm. The red light (LED) on all other alarms will shine continuously.

Warranty: 5-year limited warranty.

Standards: Underwriters Laboratories Inc. Single and Multiple Station carbon monoxide alarms UL2034.

According to Underwriters Laboratories Inc. UL2034, Section 1-1.2: “Carbon monoxide alarms covered by these requirements are intended to respond to the presence of carbon monoxide from sources such as, but not limited to, exhaust from internal-combustion engines, abnormal operation of fuel-fired appliances, and fireplaces. CO alarms are intended to alarm at carbon monoxide levels below those that could cause a loss of ability to react to the dangers of Carbon Monoxide exposure.” This CO Alarm monitors the air, and is designed to alarm before CO levels become life threatening. This allows you precious time to leave the house and correct the problem. This is only possible if alarms are located, installed, and maintained as described in this manual.
