[9.1.5] Filter Replacement
The filters do not substantially affect smoke performance even when up
to 90% of the filter is clogged. Quarterly visual inspection usually suf-
fices to determine whether the filters should be replaced because only a
high percentage of contamination affects performance. If further testing
is required, compare differential pressure readings with and without the
filters installed. If the difference exceeds 10% replace the filters. In no case
should the pressure differential fall below 0.0015 inches of water.
[9.2] Standby, Alarm, And Sensitivity Tests
[9.2.1] Standby And Trouble
Standby — If the system control panel is programmed, look for the
presence of the flashing LEDs through the transpar-
ent housing cover. The LED will flash with each communi
cation.
Trouble — If the detector LEDs do not flash, then the de-tector lacks
power (check wiring, panel pro-gramming, or power sup
ply), the detector board is missing (replace), or the unit
is defective (return for repair). Additionally, if the cover
is removed for more than 20 minutes, the LEDs of the
detector will not flash.
Test — The trouble condition can be caused intentionally to
verify correct operation of the system. Remove the detec
tor board to cause a trouble condition locally and at the
system control panel.
CAUTION
Filters require periodic cleaning or replacement, depending on the amount
of dust and dirt accumulated. Visually inspect the filters at least quarterly;
inspect them more often if the dust accumulation warrants it. See Section
[9.1.2] for more information. Replacement filters can be ordered (filter
P/N F36-09-11).
[6] Field Wiring Installation Guidelines
All wiring must be installed in compliance with the National Electrical
Code and the local codes having jurisdiction. Proper wire gauges should
be used. The conductors used to connect smoke detectors to control
panels and accessory devices should be color-coded to prevent wiring
mistakes. Improper connections can prevent a system from responding
properly in the event of a fire.
For signal wiring, (the wiring between detectors or from detectors to auxil-
iary devices), it is usually recommended that single conductor wire be no
smaller than 18 gauge. The duct smoke detector terminals accommodate
wire sizes up to 12 gauge. The last foot of conduit should be flexible
conduit (available in electrical supply houses), which facilitates easier
installation and puts less strain on the conduit holes in the housing. Solid
conduit connections may be used if desired.
Smoke detectors and alarm system control panels have specifications for
Signaling-Line Circuit (SLC) wiring. Consult the control panel manufactur-
er’s specifications for wiring requirements for the particular model control
panel being used before wiring the detector loop.
The ADP-R detector is designed for ease of wiring. The housing provides
a terminal strip with clamping plates. Wiring connections are made by
stripping about
3
⁄
8
-inch of insulation from the end of the wire, sliding
the bare end under the plate, and tightening the clamping plate screw.
Two LEDs on each duct smoke detector may light, if programmed by the
system control panel, to provide a local, visible indication. Remote LED
annunciator capability is available as an option. Each duct smoke detector
can only be wired to one remote accessory.
Different panel manufacturers offer different feature sets across their dif-
ferent panel models. As a result, certain features of the ADP-R may be
available on some control panels, but not on others. The possible features
The possible features available in the ADP-R, if supported by the control
panel are:
1. Panel controls the LED operation on sensor. Operational modes are
RED blink, RED continuous, and off.
2. The remote output of the RA400Z does not follow the condition of the
duct smoke detector LED in standby, but follows the LED condition of
the duct smoke detector in alarm.
Please refer to the operation manual for the UL listed control panel
for specific operation of the ADP-R.

Wire the ADP-R duct smoke detector per the Control Panel Installation
Manual and Figures 9, 10 or 11.

[9.1.2] Air Flow Test using Aerosol Smoke
This test is intended for low-flow systems (100-500 FPM). If the air speed
is greater than 500 FPM, use a conventional manometer to measure differ-
ential pressure between the sampling tubes, as described in 9.1.1.
Drill a
1
⁄
4
″ hole 3 feet upstream from the duct smoke detector. With
the air handler on, measure the air velocity with an anemometer. Air
speed must be at least 100 FPM. Spray aerosol smoke into the duct
through the
1
⁄
4
″ hole for five seconds. Wait two minutes for the duct
smoke detector to alarm. If the duct smoke detector alarms, air is flow-
ing through the detector. Remove the duct smoke detector cover and
blow out the residual aerosol smoke from the chamber and reset the
duct smoke detector. Use duct tape to seal the aerosol smoke entry hole.
*Aerosol smoke can be purchased from Home Safeguard Industries,
Malibu, CA. Phone: 310/457-5813.
[9.1.3] Smoke Entry Test
To determine if smoke is capable of entering the sensing chamber, visually
identify any obstructions. Plug the exhaust and sampling tube holes to
prevent ducted air from carrying smoke away from the detector head, then
blow smoke such as cigarette, cotton wick, or punk directly at the head to
cause an alarm. REMEMBER TO REMOVE THE PLUGS AFTER THIS TEST,
OR THE DETECTOR WILL NOT FUNCTION PROPERLY.
[9.1.4] Air Flow Test using Dwyer Series 607 Differential Pressure
Transmitter
Verify the air speed of the duct using an anemometer. Air speed must be at
least 100 FPM. Wire the Dwyer transmitter as shown in Figure 8. Connect
the leads of the meter to either side of the 1000Ω resistor. Allow unit to
warm up for 15 seconds. With both HIGH and LOW pressure ports open to
ambient air, measure and record the voltage drop across the 1000Ω resistor
(measurement 1), 4.00 volts is typical. Using flexible tubing and rubber
stoppers, connect the HIGH side of the transmitter to the sampling tube of
the duct smoke detector housing, and the LOW side of the transmitter to
the exhaust tube of the duct smoke detector housing. Measure and record
the voltage drop across the 1000Ω resistor (measurement 2). Subtract the
voltage recorded in measurement 1 from the voltage recorded in measure-
ment 2. If the difference is greater than 0.15 volts, there is enough air flow
through the duct smoke detector for proper operation.
[7] Perform Detector Check
1. Perform STANDBY AND TROUBLE TEST per Section [9.2.1].
2. Perform MAGNET TEST per Section [9.2.2.1]. The
RTS451 test of Section [9.2.2.2] may substitute for this requirement.
3. Perform AIR FLOW TEST per Section [9.1].
4. Perform SMOKE RESPONSE TEST per Section [9.1.1].
[8] Install The Cover
Install the cover using the six screws that are captured in the housing
cover. Be certain filters are installed as specified in Section [5]. Make sure
that the cover fits into the base groove and that all gaskets are in their
proper positions. Tighten the six screws.
[9] Duct Smoke Detector Maintenance and Test Procedures
Test and maintain duct smoke detectors as recommended in NFPA 72. The
tests contained in this manual were devised to assist maintenance person-
nel in verification of proper detector operation.
Before conducting these tests, notify the proper authorities that the smoke
detection system will be temporarily out of service. Disable the device or
system under test to prevent unwanted alarms.
[9.1] Smoke Entry Tests
[9.1.1] Air Flow
This product is designed to operate over an extended air speed range of 100
to 4000 FPM. To verify sufficient sampling of ducted air, turn the air han-
dler on and use a manometer to measure the differential pressure between
the two sampling tubes. The differential pressure should measure at least
0.0015 inches of water and no more than 1.2 inches of water. Because most
commercially available manometers cannot accurately measure very low
pressure differentials, applications with less than 500 FPM of duct air speed
may require one of the following: 1) the use of a current-sourcing pressure
transmitter (Dwyer Series 607) per Section 9.1.4 or; 2) the use of aerosol
smoke per section 9.1.2.
