Knockouts
The mounting surface should be solid and vibration free.
• Selecta location that is mostlikely to intercept an intrudermoving
across the coverage pattern. The recommended mounting
height range is 6.5 ft. to 8.5 ft. (2 m to 2.6 m).
• Remove the cover. Insert a thin flathead screwdriver into the
notch at the bottom of the cover and pry up.
• Remove the circuit board by depressing the circuit board retainer
tab and lifting the board out from the enclosure. Then remove
the mirror by sliding it towards the bottom and out of its tracks.
• Open the knock-out wire entrance and route the wiring through.
3.1 Surface or Corner Mounting
• Open two holes for surface or corner mounting.
• Mark the location for the mounting screws. Use the enclosure
as a template. Pre-start the mounting screws.
• Securely attach the detector.
• Replace the circuit board/mirror unit.
• Select the VerticalAngle.
Mirror Information: The mirror is adjustable from +1° to -18°
verticallyby sliding the mirror forward or back and ±10° horizontally
by rocking the mirror side to side. To change the mirror, just pull it
out from its resting grooves.
NOTE: Excessive handling of the mirror surfaces may lead to
performance degradation.
- The following chart will help you set the correct Vertical
Angle based on the mounting height, mirror type, and
desired range.

- The angle adjust markings are on the mirror. Slide the
mirror forward or back until the angle hash marks are in-
line with the markers on each side of the frame.
3.0 Wiring
Only apply power after all connections have been
made and inspected.
• Connect wiring as shown.
NOTE: Do not coil excess wiring inside unit.
• Seal the Wire Entrance using the foam plug provided.
Terminal Descriptions
•1 (-) & 2 (+): Input Power. Use no smaller than #22 AWG
(0.8 mm) wire pair.
•3, 4, 5: Form "C" reed relay contacts rated at 3 W, 125 mA,
28 VDC maximum for DC resistive loads and protected by a
4.7 ohm resistor in the common "C" leg of the relay. Do not use
with capacitive or inductive loads.
•6 & 7: Tamper Contact, rated 28 VDC, 125 mA.
•8: Trouble. Solid state open collector; maximum current load is
25 mA. Shorts to ground (-) when the detector is in a Trouble
condition.

5.1 S1 - LED Operation
•ON: Allows the LED to operate when activated by alarm.
•OFF: The LED will not operate on alarm.
5.2 S2 - Sensitivity Mode
•Standard Sensitivity: Recommended setting for maximum
false alarm immunity. Tolerates environment extremes on this
setting. Not recommended for Long Range or Barrier type
patterns. The detector is shipped in Standard Sensitivity
mode.
•Intermediate Sensitivity: Recommendedsetting for anylocation
where an intruder is expected to cover only a small portion of the
protected area. Tolerates normal environments on this setting.
This setting will improve your intruder catch performance.
5.3 S3 and S4 - Motion Monitor:
Set for the desired Motion Monitor time (see Supervision
Features). The detector is shipped with the Motion Monitor
feature disabled.
6.0 Setup and Walk Testing
Before walk testing, the system should be fully wired,
powered, and programmed.
• Turn LED Switch ON.
• Replace the front cover.
NOTE: All testing must be performed with the front
cover in place.
• Wait at least two minutes (with no motion in the
coverage area) for the detector to setup.
• Walk test across the coverage pattern.
• The edge of the coverage is determined by activation of the
LED.
• Walk test the unit from both directions to determine the
boundaries.
7.0 Supervision Features
A supervision trouble condition is indicated at the detector by the
LED. The LED indicates the cause of the trouble using coded
pulses. The trouble signal activates the Trouble output available
at Terminal 8, which should be connected to a 24-hour zone.
The supervision features function as follows:
•PIR: PIRoperation is checkedelectronically approximately every
12 hours. If the circuit fails, the LED will pulse four times, the
Trouble output will activate and the unit must be replaced.
•Motion Monitor Supervision: This feature verifies that the
detector has a clear view of the detection area.
- When selected, a supervision timer is activated. A trouble
condition will be indicated if the detector has not alarmed at
least once during the selected time period (this feature can be
disabled by placing both switches [S3 and S4] in the OFF
position). The time period selected should be long enough to
allow adequate time for holiday weekends.
- If the time period selected has elapsed from the last alarm,
the LED will flash two times and the Trouble output will activate.
The following chart displays the LED response to the supervision
features: LED Cause

(replace detector)
• Trouble Reset: An alarm activation will reset a motion monitor
trouble condition.
8.0 Maintenance
At least once a year, the range and coverage should be checked
in accordance with the Walk Testing section. To ensure continual
daily operation, the end user should be instructed to daily walk
through the outer edge of the coverage pattern and observe the
LED operation (if used). This assures an alarm output prior to
arming.

9.0 Coverage Patterns
• Refer to the mirror module and pattern drawings for masking information.
• Before masking, be sure the chosen mirror surface is the correct one. When removing masking, remember, many adhesives will
either destroy the mirror’s surface or leave residue behind to reduce coverage performance.
• This product is factory assembled with the look down zones (O, P, and Q) masked out. If you wish to use these zones, simply remove
the masking tape from the lens.

10.0 Instructions for Installations Containing Pets
The Pet Avoidance Mirror is intended to provide protection in installations where pets are allowed to move about freely.
• Adjust the Vertical Angle to 0° when using the Pet Avoidance Mirror.
• Because the unit will be installed lower than normal, be sure to position the unit so that it has a clear line-of-sight across the room.
• To provide an accurate safety margin, install the unit no lower than twice the height of the pet, and never lower than 3 ft. (1 m).
• Make sure the field of view is free of all furniture or other objects which the pet could climb or jump, resulting in an unwanted alarm.
