The BRK Model CO250B is a basic carbon monoxide alarm designed to provide early warning of the presence of carbon monoxide. It features an electrochemical carbon monoxide sensor, an 85dB horn, a full function test switch, and a red LED light that indicates DC power or alarm.

The CO250B features a 9V Lithium battery that lasts up to 5 years and is a better value for facility managers. This alarm has two silence features.

• Low Battery Silence: Temporarily silence the low battery chirp for up to eight hours.
• Alarm Silence: Silence alarm for several minutes.

It also features a tamper-resistant locking pin that locks alarm cover to prevent the removal of the battery. Perfect for apartment, dormitory, or hotel applications. The compact, low-profile design complements any décor.

Battery installation and removal can occur while the unit is mounted to the ceiling or wall via the hinged cover. When the voltage drops to a pre-set warning level, the horn will “chirp” approximately once per minute to indicate a fresh battery is needed. To ensure the battery is always replaced properly, the cover is designed to resist closing when the battery is missing. Designed for wall or ceiling mounting. Includes mounting anchors and screws.

The BRK Model CO250 is specifically designed for residential and institutional applications including sleeping rooms of hospitals, hotels, motels, dormitories, and other multifamily dwellings as defined in standard NFPA 101. Model CO250 has been fully tested and complies with, UL2034, NFPA 720, and NFPA 101 and other agencies that model their codes after the above agencies. It meets building codes where battery-operated carbon monoxide alarms with silence are required and with model building codes published by the ICC.
