[6.2.2.2] RTS451/RTS451KEY Remote Test Station
The RTS451/RTS451KEY Remote Test Station facilitates
test of the alarm capability of the duct smoke detec-
tor as indicated in the RTS451/RTS451KEY manual. The
DH100ACDCP duct smoke detector can be reset by the
RTS451/RTS451KEY. If a system control panel is used, the
panel itself may also require testing.
To install the RTS451/RTS451KEY, connect the device as
shown in Figure 9; wire runs must be limited to 25 ohms
or less per interconnecting wire.
Please note that the magnetic coil supplied with the
RTS451 and RTS451KEY is not required when these
accessories are used with the DH100ACDCP detectors.
The functionality of the magnetic coil has been designed
into the circuitry of the new Innovair™ duct smoke detec-
tors.
[6.2.2.3] SSK451 Multi-Signaling Accessory
The System Sensor SSK451 Multi-Signaling accessory
combines a sounder feature with a key activated test and
reset function. green, amber and red LEDs provide a visual
indication of power, trouble, and alarm respectively. An
optional strobe (PS24LO) with a smoke lens can be added
to conform to the codes of certain jurisdictions.
To install the SSK451, connect the device as shown in figure 12.

[6.2.3] Sensitivity Tests
[6.2.3.1] MOD400 or MOD400R Test
After verification of alarm capability, use the MOD400R test
module with a voltmeter to check detector sensitivity as
indicated in the test module’s manual. The housing cover
must be removed to perform this test.
If test module readings indicate that the detector head is
outside of the acceptable range that is printed on the label
of the detector, the detector chamber requires cleaning per
Section [7] of this manual.
[7] Detector Cleaning Procedures
Notify the proper authorities that the smoke detector sys-
tem 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.
[7.1] Air Filters
1. Turn off power to the system.
2. Remove and inspect sampling tube filters.
3. If filters are heavily coated with dirt, replace them with
new filters. If they are not heavily coated, use a vacuum
cleaner or compressed air nozzle to remove dust, then
reinstall the filters.
[7.2] Photo Detector Boards
1. Remove the screen by gently grasping on each side and
pulling straight off.
2. Lift the photo chamber in the same fashion. Vacuum
the screen and cover. Use clean, compressed air to
loosen and blow out any remaining debris. Replacement
screens (S08-39-01) are available.
3. Vacuum photo chamber, then use clean compressed air
to blow area clean.
4. Replace the chamber by pressing it onto the base.
Press the screen into place. It should fit tightly on the
chamber.
