Description:

BRK Model CO250 is a single station carbon monoxide alarm 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.

BRK Model CO250 is a state of the art carbon monoxide alarm designed to provide

early warning of the presence of carbon monoxide. It features an electrochemi-

cal 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 alkaline

battery and the CO250LB a 9V 5 year lithium battery. 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 removal of battery.

Perfect for apartment, dormitory or hotel applications. The compact, low proﬁle de-

sign complements any décor. Battery installation and removal can occur while the

unit is mounted to the ceiling or wall via the hinged cover. When voltage drops to

a pre-set warning level, the horn will “chirp” approximately once per minute to in-

dicate a fresh battery is needed. To insure the battery is always replaced properly,

the cover is designed to resist closing when

the battery is missing. Designed

for wall or ceiling mount-

ing. Includes mount-

ing anchors and

screws.

INSTALLATION OF ALARM

The carbon monoxide alarm shall be a BRK Model CO250 and shall provide at a

minimum the following features and functions:

1. An electrochemical CO sensor.

2. The unit shall be capable of self restoring.

3. The unit shall have an “End of Life” signal after 10 years (120 months) of operation.

This signal should be capable of temporarily being silenced for up to 2 days. After

about 2 days, the signal will resume. After about 2-3 weeks the signal cannot be

silenced.

4. Powered by a supervised 9V battery and a solid state piezo horn rated at 85dB at

10 ft.

5. A visual LED power-on indicator to conﬁrm unit is receiving power or is in alarm.

6. A test/silence button to check all alarm functions and to silence any nuisance

alarms. In addition, the unit shall have a low battery silence feature to quiet

the low battery chirp for up to eight hours.

7. A tamper resistant locking pin should be provided that locks alarm cover to prevent

removal of battery.

8. The CO sensor is adjusted not to detect CO levels below 30 PPM and will not

alarm when exposed to constant levels of 30 PPM for 30 days. It will alarm at the

following levels: 400 PPM CO between 4 and 15 minutes, 150 PPM CO between 10

and 50 minutes and 70 PPM CO between 60 and 240 minutes.

9. The unit shall be capable of operating between 40°F (4°C) and 100°F (38°C) and

relative humidity between 10% and 95%.

10. The unit shall contain mounting hardware and shall be listed for wall or ceiling
