INSTALLATION AND MAINTENANCE INSTRUCTIONS
HD202B
Addressable Heat Detector
Before Installing
NOTICE
: This manual should be left with the owner/user of this equipment.
IMPORTANT
: This detector used with the HD10X base must be tested and maintained regularly following NFPA 72
requirements. The detector should be cleaned at least once a year.
General Description
This detector can be used in all areas where heat detector is required. It is suited for fires ranging from smoldering to flaming
fires.
This detector is designed to provide open area protection and to be used with HST series addressable fire alarm control panel.
Two LEDs on each detector provide local 360° visible for indication of status. In the normal condition the LEDs flash red
every scan time of panel. When the detector senses heat and goes into alarm the LEDs will latch on red.
The alarm can be reset only by a momentary power interruption.

Installation Guidelines (See Figure 2)
All wiring must be installed in compliance with the local codes having jurisdiction. Proper wire gauges should be used. The
conductors used to connect heat detectors to control panels and accessory devices should be color-coded to reduce the
likelihood of wiring errors. Improper connections can prevent a system from responding properly in the event of a fire.
For signal wiring (the wiring between interconnected detectors), it is recommended that the wire be no smaller than 1.0
square mm. Wire sizes up to 2.5 square mm may be used with the base. For best system performance. The Loop (+) and
Loop(-) wires should be twisted pair and installed in separate grounded conduit to protect the loop from extraneous electrical
interference.
Heat detector and fire alarm system control panels have specifications for allowable loop resistance. Consult the control
panel manufacturer’s for the total loop resistance allowed for the particular model control panel being used before are made
by simply stripping about 3/8 inches (9.5 mm) insulation from the end of the wire. Sliding the bare end of the wire under the
clamping plate.
The wiring of the detector base should be checked before the detector heads are installed in them. The wiring should be
checked for continuity ,polarity in the base, and dielectric tests.
