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 (63
q
C) 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.
