Specifications include, but are not limited to: 2.1.1.The combination smoke and carbon monoxide alarm shall be powered by a non-replaceable lithium battery with a 10-year life. The lithium battery shall be sealed in the unit to prevent removal and/or tampering and shall provide continuous power for the lifetime of the alarm. 2.1.2.The unit shall incorporate a photoelectric smoke sensor and an electrochemical carbon monoxide sensor. The CO sensor shall be of a fuel cell design and provide accuracy of +/- 20% + 15 PPM. The temperature operating range shall be between 40ºF and 100ºF (4ºC and 38ºC) and the humidity operating range shall be 10%-95% non-condensing relative humidity. 2.1.3.The alarm can be installed on the surface of any wall or ceiling following the UL/Manufacturer’s approved placement guidelines. Package shall Include mounting anchors and screws. The alarm shall incorporate an automatic activation feature that will activate the unit as soon as it is attached to the mounting bracket, no other steps are involved. 2.1.4.The alarm shall include a test button that will electronically simulate the presence of smoke and CO and cause the unit to go into both modes of alarm. This sequence tests the unit’s electronics to ensure proper operation. 2.1.5.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. 2.1.5.1. 70 PPM CO Concentration 60 – 240 Minutes 2.1.5.2. 150 PPM CO Concentration 10 – 50 Minutes 2.1.5.3. 400 PPM CO Concentration 4 – 15 Minutes 2.1.6.The alarm shall include a piezoelectric horn that is rated at 85 decibels at 10 feet. For a CO incident, the horn will sound in the repetitive manner – 4 quick beeps, voice message “Warning! Carbon Monoxide”, 4 quick beeps. In a smoke incident, the horn sounds 3 long beeps, voice message “Fire!”, 3 long beeps, repeating. The red LED will flash in conjunction with the alarm sound.
