minimum the following features and functions:

1.   An electrochemical CO sensor.

2.   The unit shall be capable of self restoring.

3.   The unit shall have an “End of Life” signal. This signal should be capable of    

temporarily being silenced for up to 2 days. After about 2 days, the signal will  

resume. After about 2-3 weeks the signal cannot be silenced. 

4.   Powered by a supervised 9V Lithium battery that will power the alarm for at least 5 

years and a solid state piezo horn rated at 85dB at 10 ft.

5.   A visual LED power-on indicator to confirm unit is receiving power or is in alarm.

6.   A test/silence button to check all alarm functions and to silence any nuisance 

alarms. In addition, the unit shall have a low battery silence feature to quiet

bit is to be provided. In addition a tamper resistant locking pin should be provided 

that locks alarm cover to prevent removal battery.

8.   The CO sensor is adjusted not to detect CO levels below 30 PPM and will not 

alarm when exposed to constant levels of 30 PPM for 30 days. It will alarm at the 

following levels: 400 PPM CO between 4 and 15 minutes, 150 PPM CO between 10 

and 50 minutes and 70 PPM CO between 60 and 240 minutes.

9.   The unit shall be capable of operating between 40°F (4°C) and 100°F (38°C) and
