Conventional Fire Alarms Carbon Monoxide Detector 250 Series The Edwards SafeAirTM 250-CO carbon monoxide (CO) detector is a device designed to alert building occupants of potentially dangerous levels of CO in the protected area. The internal electro-chemical sensor communicates with an on-board microprocessor which tracks CO levels over time. The 250-CO selfadjusts for indoor environmental changes and monitors its own performance, automatically compensating for sensitivity drift throughout the course of its service life. • lectro-chemical sensing technology E • Self-diagnostics • afeTestTM functional test feature enables full S functional test with CO gas • Built-in trouble/power supervision relay • 50mA relay contact configurable for normally 1 open or normally closed operation • Long-life six-year sensor • ransmits sensor end-of-life to the control panel T and central station if the system is monitored • Complies with UL 2075 CO standard • One-touch TEST/HUSH button • ntegrated 85 dBa temporal 4-sounder for I local notification • n-board LED provides local alarm and O trouble indication • perating temperature range: 32°F to 104°F O (0°C to 40°C) The 250-CO features a six-year end-of-life timer that will automatically trigger a warning, locally, at the control panel, and optionally, at a central monitoring station, indicating that the device should be serviced. FIRE ALARMS An integrated temporal four-horn provides local signaling capability for the 250-CO. It interfaces with any listed intrusion or fire alarm system by means of its 150mA output relay, which may be connected to the auxiliary input on the control panel. The 250-CO complies with UL 2075 requirements, making it suitable for use in residential and commercial applications.
