INSTALLATION OF ALARM
The CO alarm shall be a BRK Model CO910V and shall provide at a minimum the 
following features and functions:
1. An electrochemical CO sensor.
2. A Voice Warning of danger detected (Carbon Monoxide) in addition to speaking one 
of 11 pre-programmed locations, e.g. “Warning, Evacuate, CO in Basement”.
3. The unit shall have a lower and varying horn frequency to make it easier for the 
elderly with normal age related hearing loss to better hear the horn.
4. Be capable of self restoring.
5. Powered by a sealed 10-year lithium powercell with a tamperproof design. The 
tamperproof design shall not allow the powercell to be removed. A low power 
warning indicator shall cause the alarm to “chirp” when it reaches the end of 
its service life and needs to be replaced. Upon end of life, the unit shall meet UL 
requirements for disabling the alarm and the non-reinstallation of unit to 
mounting bracket.
6. A visual LED power-on indicator to confirm unit is receiving power or is in alarm.
7. A full function test button. The test button should check all alarm functions by 
stimulating the chamber to simulate a CO condition, causing the unit to alarm. 
8. Two Silence features - Low Battery Silence: Silence low battery chirp for up to 8 
hours. Alarm Silence: Temporarily silence unwanted nuisance alarms.
9. A tamper resistant locking pin that locks alarm to the mounting bracket.
10. The unit shall be capable of operating between 40°F (4°C) and 100°F (38°C) and 
relative humidity between 10% and 90%.
11. The unit shall contain mounting hardware and shall be listed for wall or ceiling 
mounting.
12. The unit shall at a minimum meet the requirements of UL2034, CSFM, NFPA 720, 
NFPA 101, ICC.
