Model 885WP-B Weatherproof Heat Detector
with Fixed Temperature Alarm
Wiring Installation Guidelines
Please refer to insert for the Limitations of Fire Alarm Systems (I56-1558-00)
System Sensor warrants its enclosed heat detector to be free
from defects in materials and workmanship under normal use
and service for a period of three years from date of
manufacture. System Sensor makes no other express warranty
for this HEAT detector. No agent, representative, dealer, or
employee of the Company has the authority to increase or alter
the obligations or limitations of this Warranty. The Company’s
obligation of this Warranty shall be limited to the repair or
replacement of any part of the smoke detector which is
found to be defective in materials or workmanship under
normal use and service during the three year period
ear Limited W
commencing with the date of manufacture. After phoning System
Sensor for a Return Authorization Number, return defective units
postage prepaid to the Company. Please include a note describing
the malfunction and suspected cause of failure. The Company shall
not be obligated to repair or replace units which are found to be
defective because of damage, unreasonable use, modifications, or
alterations occurring after the date of manufacture. In no case shall

Please thoroughly read System Sensor manual which
provides detailed information on detector spacing, placement, zoning, wiring, and special applications. Copies of
this manual are available at no charge from System
Sensor.
NOTICE: This manual shall be left with the owner/user
of this equipment.
IMPORTANT: This detector must be tested and maintained regularly in accordance with the requirements of
the local standards and regulations. The detector should be
cleaned at least once a year.

Model 885WP-B is a 2-wire fixed temperature (63qC) heat
detector. This detector is designed to provide open area
protection in areas subject to moisture. This detector is
sealed against the entry of moisture to a rating of IP67.
The LED will latch on when the detector is in alarm.
Each 885WP-B detector is used with a mounting base that
permits the detector to be mounted directly to a 50 mm or
60 mm junction box.
This detector includes a tamper-resistant feature that
prevents its removal from the mounting base without the
use of a key. To make the detector tamper-resistant,
remove the tab from the tamper arm on the mounting base
using a cutting tool. Remove the tamper key from the
center of the mounting base by twisting it back and forth
several times (see
). Once the detector is installed,
it may be removed from the mounting base by inserting
the T-shaped end of the key into the slot on the side of the
unit and rotating the detector counter-clockwise.
This detector provides six wires which are divided into
three groups, separately two red, two white and two black
wires. Refer to

Red wire: Power / Detector Circuit +ve
Black wire Power / Detector Circuit -ve (the power and
the LED uses the same cathode)

Detectors must be tested after installation as well as after
each time maintenance is performed.
Test the 885WP-B as follows:
To test the 885WP-B you need a hair dryer. From the
side of the detector, direct the heat toward the sensor.
Hold the heat source about 15 cm away to prevent
damage and apply heat to the cover during testing
until it alarms.
