7 Testing

Using a certified gas with a concentration other than the one listed for this detector
when conducting a calibration verification test (bump test) will produce inaccurate
readings. This means that higher levels of the gas being monitored may be present and
could result in overexposure. For proper use, see supervisor or User manual, or
contact Technical Support at 1-844-325-3050.
All CD-6B units are factory calibrated and 100% tested for proper operation. During normal operation, the green
status indicator LED light will be on steady and the alarm relays will be in standby mode.
The unit also performs a regular automatic self-test during normal operation. If the unit detects an improper voltage
or inoperable component, it will default into Error mode. In error mode, the Alarm 1 Relay will be activated if tFS is
On, the unit will display the error code, the green status indicator LED light will flash, and the buzzer will chirp
intermittently.
7.1 Testing
Before performing a test, check that the green CD-6B status indicator LED light is illuminated continuously. If not, do
not proceed with the tests. If the unit is in error mode, contact your local representative or Macurco technical
support representative for information on resolving the problem.

An operation test will initiate the following sequence of tests:
1. Buzzer – On for 3 seconds, display flashing bUZ when buzzer is On.

To perform an operation test,
1. Remove the single screw in the middle of the front cover of the CD-6B.
2. Remove the front cover.

5. Locate the button labeled ENTER/TEST on the left side of the printed circuit board. Press ENTER/TEST.
6. The CD-6B will step through an operation test as described above.
7. When testing is completed, reassemble the unit.

7.1.2 Manual Operation Test

This option gives the user the opportunity to manually initiate an individual test for the buzzer (bUZ), Alarm 1 Relay
