required continue with Step 4, otherwise skip to Step 7.
4. Remove the chamber cover/screen assembly by pulling it straight out.
5. Use a vacuum cleaner or compressed air to remove dust and debris from
the sensing chamber.
6. Reinstall the chamber cover/screen assembly by sliding the edge over the
sensing chamber. Turn until it is firmly in place.
7. Replace the cover using the LEDs to align the cover and then gently
pushing it until it locks into place.
8. Reinstall the detector.
[9.2]REINSTALLATION
1. Reinstall the detector in its housing.
2. Restore system power.
3. Perform Detector Check.
4. Notify the proper authorities testing has been completed and the smoke
detector system is back in operation.
[10]SENSOR REPLACEMENT
1. Remove the sensor head by rotating counterclockwise.
2. Pull gently to remove it.
3. To replace the sensor head, align the mounting features and rotate clock-

Note: If using a RA400Z, the tab should be broken for use with the intelli-
gent duct smoke detector. If using RA100Z, ensure that jumper is removed
The RTS451/RTS151/RTS451KEY/RTS151KEY Remote Test Station facilitates
test of the alarm capability of the duct smoke detector. These accessories pro-
vide the stimulus to initiate an alarm condition at the detector. The DNRHS
duct smoke detector must be reset by the system control panel.
