HST HD201B Installation And Maintenance Instructions

INSTALLATION AND MAINTENANCE INSTRUCTIONS
HD201B
Addressable Photoelectric Smoke 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 photoelectric smoke detector is required. It is suited for fires ranging from
smoldering to flaming fires.
This detector uses a state of-the-art optical sensing chamber, it 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 smoke 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 smoke 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.
Smoke 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.
