No. 996EX/998EX
PASSIVE INFRARED
MOTION DETECTORS
GENERAL INFORMATION
These passive infrared motion detectors are versatile wall-
mounted units employing Fresnel lenses and offering effi-
cient protection patterns for commercial and residential
applications. Best coverage will be obtained if mounting is
selected such that the likely direction of intruder motion is
across the pattern.
The 998EX detector is equipped with Òdownward-lookingÓ
optics to cover the normally ÒdeadÓ zone directly beneath a
detector (not present on the 996EX).
The detectors are shipped with the standard wide angle
lens installed. An interchangeable lens Ð the 99LR Long
Range lens, is supplied with the 998EX detector, but is an
optional lens for the 996EX. An optional swivel mounting
bracket is available under part number 998SB.

INSTALLATION
Normal Surface Mounting
Mount the unit to a firm vertical surface. The wall wiring
hole should be no more than 8mm diameter.
1.
Remove the front cover as shown in Figure 1.
2.
Refer to Figure 2. Knockout holes ÒAÓ in the base are
for normal surface mounting on a wall (slide PC board
up for access to bottom holes, down for access to
top holes). For corner mounting, see Corner
Mounting. Also break out the desired wire entry hole
at this time (marked X1 or X2 in Fig. 2).
3.
Feed wiring emerging from the wall through the wire
access hole near the top of the detector base. Make
sure wires have sufficient slack to allow the PC board
to be moved up and down freely when the wires are
connected to the terminals on the board.
Mount the base. Note the mounting orientation of this
4.
detector – wire entry at the top, lens at the bottom!
5.
Refer to the WIRING CONNECTIONS section before
replacing the front cover.
Corner Mounting
Knockout holes ÒBÓ in the base are used for corner mounting
on a wall (slide PC board up for access to bottom holes, down
for access to top holes).and mount in selected corner with 4
screws (see Fig. 3).
Note the mounting orientation of this detector – wire entry
at the top, lens at the bottom! Make sure the board is posi-
tioned so that the arrow is in line with the appropriate setting
on the graduated scale (see Fig. 5 and Table 1).

Changing Lenses (if required)
1.
Remove front cover.
2.
Release the lens support frame located in front cover as
follows: insert the blade of a small screwdriver between
the locking tab and the detector case in each of the four
corners of the frame, and lever each tab upward to
release. See Figure 4. When all four corners are
released, remove the lens support frame.
3.
Remove the existing lens and replace with the replace-
ment lens. The lens must be installed with the
smooth side facing outward. Also, the lens should
be oriented with its part number on the upper right-
hand side (see Fig. 4). Be sure to center the lens.
Note: Lens surface should be free of dirt, foreign mat-
ter and fingerprints. Use a clean dry soft cloth to wipe
lens surfaces.
4.
Insert the lens support frame into its original position and
then press downward on the frame so that the lens lock-
ing tabs snap into position in each of the four corners.
5.
Refer to Vertical Pattern Adjustment and Table 1 for
(998EX ONLY)
recommended detector pattern setting for various
mounting heights and protection ranges.
6.
Replace front cover.
Horizontal Adjustment of Lens
The protection pattern can be moved to the left or right by
horizontal adjustment as follows:
3m
1.
Remove front cover.
2.
Grasp the lens firmly on both sides (front and back) and
slide the lens to the left or right, as needed. The lens may
be moved as much as 4¡ (from center) in either direction.
3.
Replace front cover.
24m
30m
After adjustment, conduct a walk test to ensure proper cov-
erage of the area to be protected (see ÒTest ProceduresÓ).
Vertical Pattern Adjustment
The protection pattern can be raised or lowered by re-posi-
tioning the PC board in the detector. A graduated scale to
the left of the board (see Fig. 5) indicates the approximate
number of degrees by which the pattern can be raised
(max. +5¡) or lowered (max. -20¡). To make this adjust-
ment, slide the board upward or downward by the number
of degrees required. After any adjustment, conduct a walk
test to ensure proper coverage of the area to be protected
(see ÒTest ProceduresÓ).
Table 1 indicates the recommended setting at various
mounting heights and protection ranges for each of the
available lenses.
Lens Masking
The supplied masking strips can be used to produce a pro-
tection pattern that suits the particular requirements of the
protected area, or eliminate coverage from areas where

you anticipate environmental disturbances that might
reduce the PIRÕs stability (a heater or other heat-producing
object for example). Simply peel off the appropriate pres-
sure-sensitive adhesive strip(s) and apply over the desired
lens segment(s). Be sure to affix the masking strips to the
inside of the lens (not the outer, smooth side). Each lens
segment that is masked results in the elimination of one
zone of protection from the coverage pattern.

WIRING CONNECTIONS
Bring all wires in through the wire access slot at the top of
the detector base (near the terminal block) and connect to
the screw terminals (see Fig. 5 for wiring details). Seal any
openings in the base with foam or RTV (not supplied) to
prevent drafts or insects from entering the unit. Apply
power only after all connections have been made and are
inspected.
LED ENABLE/DISABLE OPTION
To enable the LED, set the DIP switch #1 DOWN (see
Fig. 5 for switch location). To disable the LED, set DIP
switch #1 UP. Use a small pointed tool to move the switch
handle up or down.
PULSE COUNT OPTION
For Intermediate Pulse Count, set the Pulse Count DIP
switch #2 UP (see Fig. 5 for switch location). For Standard
Pulse Count, set DIP switch #2 DOWN. Use a small
pointed tool to move the switch handle up or down.
Standard Pulse Count: This is the recommended setting
for maximum false alarm immunity. It tolerates environ-
ment extremes on this setting.
Intermediate Pulse Count: This is the recommended set-
ting for any location where an intruder is expected to cover
only a small portion of the protected area. It tolerates nor-
mal environments on this setting.
BASE
TAMPER SWITCH
The detector is equipped with a cover tamper switch (termi-
nals 6 and 7.) These terminals should be connected to the
normally closed tamper loop on control (see Fig. 5).
LED MEMORY OF ALARM OPTION (998EX ONLY)
When used with a control that can provide a suitable
switched voltage (12V), the detector can be programmed to
provide intrusion memory, as follows:
1.
Set DIP switch # 3 DOWN (memory enabled).
2.
Connect switched 12V from the control to terminal
5 on the detector. Make sure that the proper
switched voltage is used:
System Armed:
System Disarmed:
Input Impedance:
In the disarmed mode, the LED will operate in accordance
with the LED DIP switch # 1 position.
In the armed mode, the LED is inoperative and those PIRs
that report an alarm will latch the memory circuit. When the
system is subsequently disarmed, those units with memory
of alarm will light their LEDÕs, which will stay lit until
cleared.
Arming the system again will reset the memory circuits and
extinguish the LEDs.
To clear memory at any time, momentarily arm the system,
then disarm.
