System Sensor DH200RPL - Manual (Page 4)

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 DH200RPL may be
available on some control panels, but not on others. The possible features
available in the DH200RPL, 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 while in standby. When in alarm, the LED
output of the detector and remote will be identical.
Please refer to the operation manual for the UL
listed control panel for specific operation of the DH200RPL.
Wiring Instructions
Disconnect power from the communication line before installing the
DH200RPL duct smoke detector.
Wire the DH200RPL duct smoke detector per the Control Panel Installation
Manual and Figures 9, 10 or 11.
Set the desired address on the sensor board address code wheel switches
(see Figure 7).
[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.

NOTE: Air currents inside the duct may cause excessive vibration,
especially when the longer sampling tubes are used. In these
cases a 3 inch (75mm) floor flange (available at most plumb-
ing supply stores) may be used to fasten the sampling tube to
the other side of the duct. When using the flange/connector
mounting technique, drill a 1-inch to 1
1 ⁄
4
-inch (25 to 32mm)
hole where the flange will be used.
[5] Install The Filters
To install the sampling tube filters, simply push the filters into the sam-
pling and exhaust tube holes, as shown in Figure 6. If a metal sampling
tube is used, install the filters into the tube end.
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 (0.3m) of conduit should be flex-
ible 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 DH200RPL 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 (9mm) of insulation from the end of the
wire, sliding the bare end under the plate, and tightening the clamping
plate screw.
