Install the Wiring
To install the wiring, first read the above details for the specific wiring component you are installing. Then, proceed
as follows:
1.
Make sure the power to the CD-6B is turned off.
2.
Locate the modular connectors on the back of the CD-6B. Disconnect the modular connector from the
header on the detector.
3.
Strip the insulation of each wire back approximately 1/4 in. (6.5 mm).
4.
Insert the bare wire into the terminal and tighten the screw clamp. Ensure that the wire cannot easily be
pulled from the connector.
5.
When the wires are connected, seat the modular connector into the header ensuring that the latch engages.
NOTE
: 22 to 12 AWG wire shall be used. Wire used shall meet the temperature range of the detector i.e. 32°F to
121° F (0°C to 50°C).

Operations
4.1
Power up
The CD-6B cycles through an internal self-test cycle for the first minute that it is powered. The unit will execute the
test cycle any time power is dropped and reapplied (i.e. power failure).
During the entire self-test cycle the indicator LED will flash green.
The display will flash between “Cd6b” and the firmware version for the first 2 seconds, then count down from 60 to
0 (if the display setting (dSP) is “On”).
The Alarm 1 Relay will be active for the entire power on sequence (if PUt is on). The Alarm 2 Relay and Alarm 3 Relay
will be activated for the first 10 seconds of power on (if PUt is on).
When the display countdown reaches 0, the unit will take its first sample of air and the indicator LED will turn solid
green indicating the completion of the power up test.
4.2
Awareness Alarm
The Awareness Alarm is set at 0.50% vol and is not user configurable. When the gas reading is equal to or greater
than 0.50% vol, the unit indicates an Awareness Alarm.
During an Awareness Alarm, the buzzer will beep every 60 seconds. If the display is ON, the display will flash the gas
reading.
