11.2 RTS451/RTS151/RTS451kEy/RTS151kEy REMOTE TEST
STATION WITh OPTIONAL SENSOR REMOTE TEST CAPABILITy
To install the RTS451/RTS151/RTS451KEY/RTS151KEY, using the sensor with
remote test capability connect the device as shown in Figure 11; wire runs
must be limited to 25 ohms or less per interconnecting wire.

CAUTION
Canned aerosol simulated smoke (canned smoke agent) formulas will vary by
manufacturer. Misuse or overuse to these products may have long term adverse
effects on the smoke detector. Consult the canned smoke agent manufacturer’s
published instructions for any further warnings or caution statements.
[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
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-
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
provide the stimulus to initiate an alarm condition at the detector. The DNRW
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.

11.3 ADDITIONAL MODULE OPTION
The DNRW can also accommodate a relay or control module (sold separately)
within the power board side of the housing. The relay or control module must
be listed as compatible to the fire alarm control panel.
Physical Module Mounting
1) Remove the breakaway tabs at the four corners of the module
2) Locate the module at right most corner of the power board. The upper
left corner mounting hole of the module will align with a screw boss in
the housing.
3) Install a # 8 x 3/8” Plastite screw at the screw boss location
Note: See the corresponding module Installation Instructions for general de-
scription, control panel compatibility, wiring and ratings.
