Fire/CO Detection Sensors
GE Security ES-250CO Carbon Monoxide Alarm
potentially dangerous levels of CO in the protected area. The on-
board microprocessor that accurately tracks CO levels over time.
This commercial-grade detection technology results in quick
response, reliable sensing, fast reset time, and superior false alarm
immunity. Its small size allows the 250-CO to blend inconspicuously
with any decor, and its smooth contoured design is compatible with
both residential and commercial environments.

Unaffected by normal indoor temperature variations, the GE 250- CO
actually self-adjusts for environmental changes and operates reliably
under a wide variety of conditions. It also monitors its own
performance and automatically compensates for sensitivity drift
throughout the course of its service life.

Like all CO detectors, the 250-CO has a limited service life. When it
reaches this point, the 250-CO's six-year end-of-life timer
automatically triggers a warning, locally, at the control panel, and
optionally, at a central monitoring station, indicating that the device
should be serviced.

An integrated temporal four-horn provides local signaling capability
for the 250-CO, and it easily 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. Its low current
draw results in little additional demand on the system power supply.

The 250-CO fully complies with the latest UL 2075 requirements
which allows for installation in a wide range of residential and
commercial settings.
