Before installing
Please thoroughly read System Sensor manual which
provides detailed information on detector spacing, place-
ment, 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 main-
tained regularly in accordance with the requirements of
the local standards and regulations. The detector should be
cleaned at least once a year.

General Description
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.
Mounting
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.
Tamper-resistant Feature
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
Figure2
). 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.
Wiring Installation Guidelines
This detector provides six wires which are divided into
three groups, separately two red, two white and two black
wires. Refer to
Figure 3
..
Terminal Notes:
Red wire: Power / Detector Circuit +ve
Black wire Power / Detector Circuit -ve (the power and
the LED uses the same cathode)
White wire Remote LED +ve

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
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

Installation

NOTE: All wiring must conform to applicable local
codes, ordinances and regulations.
NOTE: Verify that all detector bases are installed, that the
initiating-device circuits have been tested, and
that the wiring is correct.
WARNING
Remove power from initiating-device circuits before in-
stalling detectors.
1. Place the detector on the mounting base and rotate
clockwise until it drops into place.
2. Turn the detector clockwise in the mounting base until
it clicks into place.
3. After all detectors have been installed, apply power to
the control unit or initiating-device circuits.
4. Test the detector as described in Te
Testing
.
5. Reset the detector at the system control panel.
6. Notify the proper authorities the system is in
operation.

Testing
NOTE: Before testing, notify the proper authorities that
the thermal detector system is undergoing mainte-
nance and will temporarily be out of service.
Disable the zone or system undergoing mainte-
nance to prevent unwanted alarms.
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.
A detector that fails these tests should first be cleaned as
outlined in the
Maintenance
section which follows. If
the detector still fails , it should be returned for repair.
Notify the proper authorities the system is back on line.

Maintenance
NOTE: Before removing the detector, notify the proper
authorities that the fire detection system is
undergoing maintenance and will temporarily be
out of service. Disable the zone or system
undergoing maintenance to prevent unwanted
alarms.
1. Remove the detector from the mounting base by
rotating it counter-clockwise.
2. Vacuum the metal heat collector and surrounding area.
3. Clean the surface of the detector.
4. Reinstall the detector.
5. Test the detector as described in Testing.
6. Notify the proper authorities the system is back in
operation.
