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 DNRW duct
smoke detector must be reset by the system control panel.
[11.1] OPTION 1:
REMOTE TEST USINg SENSOR WITh REMOTE TEST CAPABILITy
(WIThOUT A TEST COIL):
A sensor with suffix "R" is available for use inside the DNRW. Suffix "R"
represents a head with Remote Test Capability. Using this head inside the
DNRW eliminates the need for a test coil when wired to a RTS451/RTS151/
RTS451KEY/RTS151KEY Remote Test Station.

To install the RTS451/RTS151/RTS451KEY/RTS151KEY, using the sensor with
remote test capability connect the device as shown in Figure 9; wire runs must
be limited to 25 ohms or less per interconnecting wire.
NOTE: Resistor assembly must be in place between RA+ and OUT+
inside the DNRW for Remote Test function to operate.

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] OPTIONAL ACCESSORIES
Optional accessories include RA400Z/RA100Z, RTS451/RTS151 and

RTS451KEY/RTS151KEY.
NOTE: Ensure blue wire always remains connected to RA+ on the field
connector side of the terminal block.

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.

[11.2] OPTION 2:
REMOTE TEST USINg A TEST COIL:

The use of a remote test station requires the installation of an accessory
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 10 below for reference.
