[9]DETECTOR CLEANINg PROCEDURES
Notify the proper authorities that the smoke detector system is undergoing
maintenance, and that the system will temporarily be out of service . Disable
the zone or system undergoing maintenance to prevent unwanted alarms and
possible dispatch of the fire department .
[9.1]DETECTOR SENSOR
1 . Remove the sensor to be cleaned from the system .
2 . Remove the sensor cover by pressing firmly on each of the four removal
tabs that hold the cover in place .
3 . Vacuum the screen carefully without removing it . If further cleaning is re-
quired 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-
wise into place .

[11.1]RTS451/RTS151, RTS451KEy/RTS151KEy REMOTE TEST STATION
wITh OPTIONAL TEST COIL
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 SK-Duct
duct smoke detector must be reset by the system control panel .
NOTE: The use of a remote test station requires the installation of an acces-
sory coil, part number DCOIL, sold separately .
1) Install DCOIL in housing pocket insuring that arrow is pointing toward detector
2) Install DCOIL mounting screw
3) Connect each DCOIL lead to a Test Coil Terminal
See Figure 9 below for reference .
