SELECTING MOUNTING LOCATION
Choose a location most likely to intercept an
intruder. See detection patterns in figure 5.
The dual-element high quality sensor detects
motion across the beam. It is slightly less
sensitive when detecting motion toward the
detector.
The SRP-PET 2 performs best when provided
with a constant and stable environment.
AVOID THE FOLLOWING LOCATIONS
−
Facing direct sunlight.
−
Facing areas subject to rapid quick
temperature changes.
−
Areas with air ducts or substantial air flows.
MOUNTING THE DETECTOR
For PET immunity mount flat on the wall or in the
corner.
It is recommended to mount the detector
between 7ft and 8ft for optimal coverage, and
pet immunity.

1.
To remove the front cover, insert a flat
screwdriver in the slot between the front and
the bottom, above the holding screw hole and
push gently, until the front cover is
disengaged and the opening click is heard
(Fig 1.).
2.
To remove the PC board, carefully loosen
the holding screw located on the PC board.
3.
Break out the desired holes for proper wiring
as per fig 2.
4.
Insert the wire through the wire access hole,
and mount the detector base to the wall,
corner or ceiling with the necessary number
of screws and the suitable bracket.
5.
Reinstall the PC board, set it a low as
possible - till stopper (see fig.2). Tight the
holding screw.
6.
Access for wiring located on the PCB. See
fig 3.
7.
Replace the cover by inserting it back in
the appropriate closing pin until the closing
click is heard.

NOTES
for UL referring countries
1.
Connect the SRP-PET 2 to a “ U.L. ”
listed burglar alarm Power Supply or
control panel capable of providing
standby power for at least four (4) hours.
2.
Refer to national electric code, NFPA-70
for wiring methods.
3. The SRP-PET 2 production batch can be
identified by the 4 digits printed on the
terminal strip side of the PC board
.
TERMINAL BLOCK CONNECTIONS
Run the cable through the cable entry hole and
connect the wires in accordance with the
following instructions:
Terminal 1 - Marked - ( - 12V )
Connect to the negative Voltage output or
ground of the control panel.
Terminal 2 - Marked + ( + 12V )
Connect to a positive Voltage output of 7.8-16
Vdc source (usually from the alarm control unit)
Terminals 3 & 4 - Marked RELAY
These are the output relay contacts of the
detector. Connect to a normally closed zone in
the control panel.
Terminals 5 & 6 - Marked TAMPER
If a Tamper function is required connect these
terminals to a 24hour normally closed protective
zone in the control unit. If the front cover of the
detector is opened, an immediate alarm signal
will be sent to the control unit.
WIRE SIZE REQUIREMENTS
Use #22 AWG (0.5 mm) or wires with a larger
diameter. Use the following table to determine
required wire gauge (diameter) and length of
wire between the detector and the control panel.
Wire Length m 200 300 400 800
Wire Diameter mm .5 .75 1.0 1.5
Wire Length ft. 800 1200 2000 3400
