What's in the Box
- (10) Pro-Tech 8505 Commercial CO Alarms
Where to Put Them
Spread alarms across the open floor at one per 1,000 square feet, then cover separate offices, break rooms and any room with fuel-burning equipment. Mount each one on an inside wall about three inches above eye level, at least 1 foot from exterior doors and windows and never on an outside wall. The alarm is designed for heated and air-conditioned space from 40°F to 100°F.
Why Pro-Tech
- Alarms based on the workplace exposure limits set by OSHA, NIOSH, ACGIH and Cal/OSHA, not the home-alarm standard
- Shows the CO level continuously from 9 ppm
- Remembers the highest CO level, how long it lasted and when, with 30 days of history
- 85 dB alarm with flashing red light
- Runs on one 9V battery each, so there is no wiring
