65-2496RK/65-2499RK CO Detector • 7
Start Up
This section describes procedures to start up the CO detector and place the detector into
normal operation.
Introducing Incoming Power
1. Complete the installation procedures described earlier in this manual.
2. Verify that the power wiring to the controller is correct and secure. Refer to the
controller operator’s manual.
3. Turn on or plug in the incoming power, then turn on the controller.
4. Verify that the controller is on and operating properly. Refer to the controller
operator’s manual.
CAUTION: Allow the detector to warm up for 5 minutes before you continue with the next
section, “Setting the Zero (Fresh Air) Reading”.
Setting the Zero (Fresh Air) Reading
CAUTION: If you suspect the presence of CO in the monitoring environment, use the calibration
kit and a zero air calibration cylinder to introduce “fresh air” to the CO detector and
verify an accurate zero setting. See “Calibration” on page 13 for instructions to
introduce zero air to the CO detector.
1. Verify that the CO detector is in a fresh air environment (environment known to be
free of toxic and combustible gases, and of normal oxygen content, 20.9%).
2. Verify a reading of 0 ppm at the controller.
If the display reading is 0 ppm, start up is complete. The CO detector is in normal
operation. If the display reading is not 0 ppm, continue with step 3.
3. Perform a zero (fresh air) adjustment operation at the controller. See the controller
operator’s manual for instructions.
