Intelligent Products—DH500 Series Intelligent Air Duct Smoke Detector 17
In order for the alarm controlled relay to operate, a separate power supply
must be connected to the DH500J. The power on the SLC is not adequate
to operate the relay without supplying additional power. A separate power
supply is not required with the DH502J.
The DH500J is designed for easy wiring. The housing provides a terminal
strip with clamping plates.
To make wire connections:
1.
Strip approximately 1/2 inch of insulation from the end of the wire.
2.
Tape back and isolate the SLC cable shield from contact with any
metal object, but assure the shield continuity is preserved over the
entire length of the SLC.
3.
Slide this bare end under the plate.
4.
Tighten the clamping plate screw.
The DH500J operates from 120/240 VAC or 24 VAC/DC to operate
auxiliary functions (Figure 6).
For the 4-wire operation of the DH500J for alarm controlled relay and
auxiliary function activation:
1.
Cut the jumper wire J5, located between the two terminal strips on the
printed circuit board (Figure 6), to ensure proper power supply
supervision when the detector is used in a 4-wire application
(relay circuit is being used to control fans and dampers) and a separate
power supply is connected to the DH500J to power the alarm
activated control relay.
2.
Leave the jumper wire J5 in place when the detector is used in a
2-wire application (relay control is not being used for any control of
fans and dampers).
To complete the wiring for 110/120 VAC 4-wire operation:
1.
Connect the power supply wires to terminals 15 and 16 (Figure 6).
2.
If 220/240 VAC operation is preferred, connect the power supply
wires to terminals 16 and 17.
