Specification

Architect & Engineering Specifications
The carbon monoxide alarm shall be a Gentex Model CO1209/CO1209F or approved equal which shall provide at least the following features and
functions:
1. The carbon monoxide alarm shall utilize an electrochemical sensing element with expected 5-year life.
2. The carbon monoxide alarm is calibrated not to detect CO levels below 30PPM and will not alarm when exposed to constant levels of 30PPM for
30 days. The device will alarm at the following levels: 70 PPM CO between 1 to 4 hours. 150 PPM CO between 10 to 50 minutes. 400 PPM 4 to
15 minutes.
3. The CO1209 Series device shall have a Duracell
®
MN 1604 9VDC alkaline battery as a back-up in the event building power is lost.
4. The 9VDC battery impedance shall be verified by the circuit of the smoke/CO alarm.
5. The CO alarm shall provide an indicator when the battery is low in power or high impedance or is missing.
6. The CO alarm will provide an audible indicator at end of life of CO sensor.
7. A solid state piezo alarm rated at 85dBA at 10ft.
8. A visual LED monitor (condition indicator) will slow pulse in normal operation.
9. A red color LED will indicate presence of CO at the unit.
10. An easily accessible test button shall be provided. Push down on button for self test. Push button and hold until CO alarm activates for functional
test. If device does not go into alarm, the device is not working properly.
11. The device shall have tandem interconnect capability of up to 12 units or 6 units with relay.
12. The CO1209 Series alarm shall have the capability to tandem interconnect with all Gentex tandem capable CO alarms, smoke alarms or
combination smoke/CO alarms, including 7000/70003 Series, 9000/9003 Series, 710CS/713CS Series, 7109CS/7139CS Series, GN-200/
GN-300 Series, S1209 Series and GN-503 Series.
13. The CO alarm shall be non-latching (self-restoring).
14. Unit must be ANSI/UL 2034 listed for both wall and ceiling mount.
15. Unit shall be listed by Underwriters Laboratories and California State Fire Marshal (CSFM).
All equipment shall be completely factory assembled and tested, and the contractor shall be prepared to submit a certified letter testifying to this
condition. Alarms which do not meet all of the requirements of this specification will not be considered.
For complete product specifications, refer to product installation manual.

CO1209 Series Wiring Diagrams
LIMITATIONS:
A Maximum of 18 CO1209 Series CO
alarms may be connected together. Do
not exceed 125 feet between each alarm.
Do not exceed 1125 feet between the first
and last alarm. NOTE: Gentex CO alarms
can not be interconnected to alarms from
other manufacturers.
The CO1209 may be tandem
interconnected with current Gentex alarm
models. To interconnect with Gentex
9000 Series, 7000 Series, 710CS Series,
7109CS Series, GN-200 Series & GN-300
Series the LEGACY TANDEM WIRE
(RED/YELLOW) must be used. To
interconnect with Gentex S1209 Series,
GN-503 Series or to additional CO1209
Series, use the BROWN/YELLOW wire.
Refer to installation manual for detailed
information.
