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.

SRP-PET 2 FEATURES

∗ Immunity to animals up to 45 lbs.
∗ Dual element Pyrosensor.
∗ Hard type full pattern spherical lens.
∗ Variable pulse width adjustment.
∗ Sensitivity adjustment.
∗ Automatic temperature compensation.
∗ Low current compensation.
∗

Height installation (calibration free) from
6ft to 8ft.

∗ Environmental immunity.
∗

High - tech design.

∗ Fully insulated sensor chamber.
∗

Totally sealed sensor chamber.

AVOID THE FOLLOWING LOCATIONS

− Facing direct sunlight.

− Facing areas subject to rapid quick

temperature changes.

− Areas with air ducts or substantial air flows.

The SRP – PET 2 provide immunity to
45lbs pet active bellow 3 ft.
For better immunity, avoid installation in
area reached by pet.

FIG. 1 - REMOVAL OF FRONT COVER

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.

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.

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.

the appropriate closing pin until the closing
click is heard.

TERMINAL BLOCK CONNECTIONS

Run the cable through the cable entry hole and
connect the wires in accordance with the

NC

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.

SENSITIVITY ADJUSTMENT

The sensitivity potentiometer should be adjusted
according to the security risk level at the
installation site.
For high-risk locations, the sensitivity should be
adjusted close to MIN. In low risk situations, the
sensitivity should be adjusted closer to MAX
factory set to MIDDLE.
Always walk test and re-adjust if required.

CHANGING THE LENS

1. Remove the front cover by inserting a flat
screw driver in the appropriate slot.

2. Using a small flat screwdriver, press on
left or right side of the installed lens which
will then pop out from its side right and
left holding pins.

3. Select the desired lens and hold it while
making sure its upper holding pin is
pointed upwards.

4. Snap the lens to its place by pressing
again from outside of the front cover until
a click is heard, confirming the new lens
is tightly inserted. See fig 6.

5. Replace front cover.
