99LR LONG RANGE LENS

PROTECTION RANGE

*Important: 

When using the Long Range lens, set the PIR

for intermediate response (Pulse Count DIP switch in UP
position)

TEST PROCEDURES

Important:

Two-minute warm-up time is required after

applying power. Testing should be conducted with the pro-
tected area cleared of all people. Disarm the protective
systemÕs control during the test procedure to prevent
reporting of unwanted alarms. 

1.

Remove front cover 

and set DIP switch #2 (Pulse

Count) 

to the setting which will be used for this detec-

tor in the installation

.

The LED must be enabled at this

time (DIP switch #1 down).

2.

Replace front cover and walk through protective
zones, observing that the detectorÕs LED lights when-
ever motion is detected (the LED serves as a Walk-
Test indicator during this procedure).

3.

For the 998EX detector, check the downward-looking
zone by walking along the wall directly beneath the
detector.
The absolute range of all PIR units is subject to variation
because of different types of clothing, backgrounds and
ambient temperature. For this reason, ensure that the
most likely intruder routes are well within the PIRÕs pro-
tective zones and that walk-testing is carried out along
these routes.

After the ÒWalk-TestÓ is complete, the LED may be dis-
abled (DIP switch #1 UP). 

MAINTAINING PROPER OPERATION

In order to maintain the detector in proper working condition,
it is important that the user observe the following.
1.

Power should be provided at all times. Loss of power
to the unit will result in the alarm contacts reverting to
an alarm state. 

2.

Units should never be re-aimed or relocated without
the advice or assistance of the alarm service company.

3.

The physical surroundings of the protected area
should not be changed. If furniture or stock is moved,
or air-conditioning or additional heating is installed, the
system may have to be readjusted by the alarm ser-
vice company.

4.

Walk-tests should be conducted frequently (at least
weekly) to confirm continued proper coveage by each
detector.

TROUBLESHOOTING

INTERMITTENT ALARM (LED OPERATIVE)

A.

Rapid temperature change. Check for electric or gas
heaters, open flames, electric arcs, etc. 

Remedy:

Locate source and reposition detector.

B.

Drafts causing drapes, light fixtures, display material to
move.

Remedy: 

Eliminate source of motion.

INTERMITTENT OR CONTINUOUS ALARM

A.

DC voltage supplied to detector is inadequate, intermit-
tent, or polarity reversed.

Remedy: 

Ensure that proper polarity and adequate

voltage is supplied and that wiring is intact (no
opens/shorts) and connections secure.

B.

Protective loop is interrupted (open).

Remedy: 

Determine whether interruption is in protec-

tive loop wiring or at detectorÕs alarm relay contacts.
Disconnect protective loop at detector relay contact
terminals. Check continuity across terminals. If absent
(and proper voltage is supplied to the detector), return
unit for replacement. If present, check protective loop
wiring.

LED INOPERATIVE

A.

LED DIP switch #1 in UP position.

Remedy: 

Set DIP switch #1 in DOWN position.

B.

LED malfunction. Check for broken/shorted leads.

Remedy:

Return unit for replacement.

DETECTION AREA CHANGES

A.

Repositioned furniture or equipment in the protected
area.

Remedy:

Caution customer about layout changes.

Reposition detector.

B.

Mounting surface is unstable. A few degrees of vertical
shift can change range substantially.

Remedy:

Mount on secure surface.

PANEL INDICATES CONTINUOUS FAULT IN ZONE OF
PROTECTION CONTAINING PIRs 
(PIR’s alarm LED not lit)

Too many detectors being used in the zone. Each detector
adds 15 ohms of series resistance and the zoneÕs allow-
able loop resistance is being exceeded.

Remedy:

Reduce the number of detectors used in the zone
until the series resistance is within the allowable
loop resistance permitted by the control.

TO THE INSTALLER

Regular maintenance and inspection (at least annually)
by the installer and frequent testing by the user are vital
to continuous satisfactory operation of any alarm sys-
tem.

The installer should assume the responsibility of devel-
oping and offering a regular maintenance program to
the user, as well as acquainting the user with the proper
operation and limitations of the alarm system and its
component parts. Recommendations must be included
for a specific program of frequent testing to insure the
systemÕs operation at all times.

THE LIMITATIONS OF YOUR PASSIVE INFRARED

MOTION DETECTOR

While the Intrusion Detector is a highly reliable intrusion
detection device, it does not offer guaranteed protection
against burglary. Any Intrusion Detection device is sub-
ject to compromise or failure to warn for a variety of rea-
sons:

¥

Passive Infrared Motion Detectors can only detect
intrusion within the designed ranges as diagrammed in
this installation manual.

¥

Passive Infrared Motion Detectors do not provide volu-
metric area protection. They do create multiple beams
of protection, and intrusion can only be detected in
unobstructed areas covered by those beams.

¥

Passive Infrared Detectors cannot detect motion or
intrusion that takes place behind walls, ceilings, floors,
closed doors, glass partitions, glass doors, or win-
dows.

¥

Mechanical tampering, masking, painting or spraying
of any material on the lenses, windows or any part of
the optical system can reduce the detection ability of
the Passive Infrared Motion Detector.

¥

Passive Infrared Detectors sense changes in tempera-
ture; however, as the ambient temperature of the pro-
tected area approaches the temperature range of 32¡
to 40¡C, the detection performance can decrease.

¥

This Passive Infrared Detector will not operate without
appropriate DC power connected to it, or if the DC
power is improperly connected (i.e., reversed polarity
connections).

¥

Passive Infrared Detectors, like other electrical
devices, are subject to component failure. Even
though this equipment is designed to last as long as
10 years, the electronic components in  it could fail at
any time.

We have cited some of the most common reasons that a
Passive Infrared Motion Detector can fail to catch intru-
sion. However, this does not imply that these are the only
reasons, and therefore it is recommended that weekly
testing of this type of unit, in conjunction with weekly test-
ing of the entire alarm system, be performed to ensure
that the detectors are working properly.

Installing an alarm system may make the owner eligible
for a lower insurance rate, but an alarm system is not a
substitute for insurance. Homeowners, property owners
and renters should continue to act prudently in protecting
themselves and continue to insure their lives and property.

We continue to develop new and improved protection
devices. Users of alarm systems owe it to themselves
and their loved ones to learn about these developments.

ADEMCO SIX-YEAR LIMITED WARRANTY

Alarm Device Manufacturing Company, a Division

of Pittway Corporation, and its divisions, sub-
sidiaries and affiliates ("Seller"), 165 Eileen Way,

replacing, at its option, free of charge for materials
or labor, a detector which is proved not in compli-
ance with Seller's specifications or proves defec-
tive in materials or workmanship under normal use
and service.  Seller shall have no obligation under
this Limited Warranty or otherwise if the detector is
altered or improperly repaired or serviced by any-
one other than Ademco factory service. In case of
defect, return the detector to or an authorized dis-
tributor for an immediate replacement.

installed and maintained alarm may only reduce
the risk of a burglary, robbery, fire or other events
occurring without providing an alarm, but it is not
insurance or a guarantee that such will not occur
or that there will be no personal injury or property
loss as a result.  CONSEQUENTLY, SELLER
SHALL HAVE NO LIABILITY FOR ANY PERSON-
AL INJURY, PROPERTY DAMAGE OR OTHER

FAILED TO GIVE WARNING. HOWEVER, IF
SELLER IS HELD LIABLE, WHETHER DIRECTLY
OR INDIRECTLY, FOR ANY LOSS OR DAMAGE
ARISING UNDER THIS LIMITED WARRANTY OR
OTHERWISE, REGARDLESS OF CAUSE OR
ORIGIN, SELLER'S MAXIMUM LIABILITY SHALL
NOT IN ANY CASE EXCEED THE PURCHASE
PRICE OF THE DETECTOR, WHICH SHALL BE
THE COMPLETE AND EXCLUSIVE REMEDY
AGAINST SELLER. This warranty replaces any
previous warranties and is the only warranty made
by Seller on this detector.  No increase or alter-
ation, written or verbal, of the obligations of this
Limited Warranty is authorized.
