Cover Removal Instructions
Follow these steps to remove a sensor cover:
1. Place the sensor on the NSRT-A100 tool
aligning the locator as shown in Figure 4.
2. Grasp the sensor firmly and rotate the sensor
clockwise (about a 30° turn).
The contact blades on the sensor will engage
on the NSRT-A100 brackets, which will
prevent further rotation.
The sensor body is know disengaged from
the outer cover.
3. Pull the sensor outer cover up and away from
the NSRT-A100 tool.

Cover Replacement Instructions
Follow these steps to replace the outer cover of
the sensor onto the sensor body
1. Place the outer cover nose down on a flat
surface.
2. Align the outer cover recesses with the outer
cover keys. (See Figure 2 and Figure 3.)
Note: There are two orientations possible, however only
one way will fit.
3. With the outer cover keys aligned with outer
cover recesses press down firmly on the back
of the sensor.

Testing Smoke Sensors
Testing Smoke Sensors
This section contains information on how to
prepare, operate and storing the TSE-A100 for
the testing of photoelectric smoke sensors.
Preparing the TSE-A100
Follow these steps to assemble and start-up the
TSE-A100.
Stoppers
Telescoping
Pole
1. Remove two parts of the TSE-A100 (smoke
and fan & battery tubes from the carrying
case.
2. Screw the smoke and the fan& battery tubes
together.
3. Unscrew the combustion chamber access
cover and slide the combustion chamber out
of the fan & battery tube.

Tube
4. Unscrew the punk stick retainer.
5. Insert a punk stick.
6. Ignite the punk stick with a lighter or match.
7. Screw the punk stick retainer back into the
combustion chamber.
8. Screw the combustion chamber back into the
fan & battery tube.
Testing photoelectric sensors
After the TSE-A100 has been properly prepared,
follow these steps to test a smoke detector.
Note: Allow the punk stick to burn for 30 to 60 seconds
after igniting to provide adequate smoke
generation.
1. Rotate the combustion chamber so the power
indicator screw lines up with the number
two.
Note: The fan powers up and a steady flow of smoke is
released from the tip of the
TSE-A100. If not check the batteries.
2. Extend the tip of the TSE-A100 to within 6
to 8 inches (extends from 5.25 to 14.1 feet)
of the sensor.

Testing Smoke Sensors
Testing a Duct Detector
The SD505-ADH automatically performs a
sensitivity test every three hours. The sensitivity
test is performed automatically so there is no
need for a remote test station. The status of each
individual duct detector is available at the main
or remote LCD annunciators. Since the specific
duct detector that is in alarm or trouble is
displayed on the annunciators it is not necessary
to have a remote indicator light. (Per exception
listed in NFPA code section 5-10.6.8 1996
edition.)
The pressure differential between the inlet
tube and the exhaust tube should be greater
than 0.08” and less than 1.0’ of water. See
Figure 8.
To Manually test the duct detector:
1. Unscrew the four duct detector cover screws.
See Figure 7.

3. Test the smoke detector
For photoelectric and ionization sensor use
the TSE-A100 tester. See “Testing Smoke
Sensors” on page 5.
For heat sensors use the HDT-380 Heat
Sensor Tester. See “Testing Heat Sensors”
on page 8.
4. Replace the duct detector cover and secure it
down with the four duct detector cover
screws. See Figure 7.
Figure 7: Duct Detector Cover Screw Locations
2. Verify the proper air sampling rate with a
differential pressure gauge (Dwyer Model
4000 or equivalent).

Testing Heat Sensors
Follow these steps to test heat sensors with the
HDT-380 heat sensor tester.
Warning!: Do Not use the HDT-380 to test non-restorable
heat sensors or detectors.
1. Connect the power connector from the
HDT-380 into the battery pack. See Figure 9
and Figure 10.
2. Extend the adjustable aluminum pole of the
HDT-380 up to the heat sensor. See Figure
10.
Friction Locks
3. Tighten the friction lock to hold pole to its
extended position.
4. Place the HDT-380 over the heat sensor. See
Figure 1.
5. Turn the HDT-380 power switch on. See
Figure 10.
The red LED at the bottom of the HDT-380
will turn on when the power switch is turned
on.
6. When the sensor alarms (about 5 to 15
seconds) remove the HDT-380 from the
sensor and turn the power switch off.
Power Connector
7. Return the HDT-380 to its carrying case
when all sensors are tested.
