PRODUCT DESCRIPTION 3
DFW-915
WIRELESS SUPERVISED PIR
MOTION DETECTOR
The DFW is a battery powered passive infrared
motion detector with a built-in transmitter.
This transmitter can be used in a variety of motion
detection applications. When the passive infrared
sensor detects motion in its field of view, the
transmitter sends a wireless signal to the receiver.
The DFW sends three different signals: “Alarm”,
“Low Battery” and “Tamper”.
In a typical installation, the motion detector is wall
mounted indoors.
With PET IMMUNITY up to 27Kg
The sensor will monitor the infrared level in its
detection pattern. If the level increases or decreases rapidly (as when a person moves through
the area) the transmitter triggers, sending an
alarm signal to the receiver.
The unit is powered from a 3 volt lithium battery.
The life of the battery depends upon the activity in
the area where the detector is installed. When the
battery is low, a low battery signal will be sent to
the receiver.
If the detector cover is removed, the tamper switch
triggers the transmitter to send an alarm.
The DFW has a unique Automatic Power Saver
(APS) circuit designed to conserve battery life.
This APS circuit rearms the transmitter 2 minutes
after the last movement has been detected.

FEATURES
DETECTION PATTERN
TYPICAL INSTALLATION
Select the mounting location so that an intruder
will cross the beams of the selected pattern.
Since the detector is a wireless transmitter, do not
install it in areas where large metal objects could
interfere with the transmission of signals.
Low current ASIC PIR technology
Powered by a 3 volt lithium battery
Built in Automatic Power Saver (APS)
Low battery report
Avoid mounting the detector as follows:
Tamper report
Facing a door with a wireless door/window
transmitter.
Facing direct sunlight.
Facing areas that may change temperature
rapidly.
Facing an air duct or areas with substantial
airflows.
On or near metal surfaces.
Walk test mode 1 for PIR coverage
Walk test mode 2 for RF signal
Pet immune up to 27Kg
Available in 915Mhz
Adjustable Mounting Bracket
2 Transmission modes, power save (normal)
and Frequent (test)
The DFW performs best when provided with a
constant and stable environment.
REMOVAL OF FRONT COVER
MOUNTING DETECTOR BASE
1. To remove the front cover, unscrew the holding
screw and gently raise the front cover.
2. To remove the PCB, carefully unscrew the
holding screw located on the PCB.
3. Knock out the desired holes for installation.
4. Mount the detector base to the wall, corner.
5. Reinstall the PCB by fully tightening the holding screw.
6. Install the battery in the battery holder observing the polarity.
7. Replace the cover by inserting it back in the
appropriate closing pins and screw in the
holding screw.
SETTING-UP THE DETECTOR LAYOUT

SETTING THE PET IMMUNITY SWITCH
PIR Adjust Potentiometer
Use this potentiometer to adjust the detection
sensitivity between 68% and 100% (factory set
to 84%). Rotate the potentiometer clockwise to
increase sensitivity. Rotate the potentiometer
counter-clockwise to decrease sensitivity.
Pulse Width Switch
The sensitivity adjustment switch sets up the
detector for normal or harsh environment conditions.
Position 1= Normal
Position AUTO = Harsh
The “1” position setting is for normal operation.
The “AUTO” position setting is for harsh environment locations with air drafts.

Setting Transmission Mode
The transmission mode is changed by moving
the jumper pins on the TRANS board, from one
option to the other.
Normal:
When the IR motion is detected, an RF transmission will be sent, then the DFW will save
power and not transmit for another 2 minutes.
Test:
In this mode every time IR motion is detected,
an RF transmission will be sent. This mode will
not time out, making it ideal for a door minder
situation.

TEST PUSHBUTTON
The Test Pushbutton is located below the
Tamper switch.
This button is used to activate Walk test mode 1
and 2.
WALK TEST MODE 1 (PIR COVERAGE)
WALL INSTALLATION
WALK TEST MODE 2 (RF SIGNAL)
Pressing the Test Pushbutton for at least 4
seconds, (until the LED flashes 4 times) will
activate both the LED and an RF transmission
with IR detection, for 1 minute.
Note. The PIR TRANS Jumper must be set to Normal
mode, no RF transmission will be sent if set to Test
mode
Press the Test Pushbutton for a short time (less
than 1 second). This activates the LED to trigger
with IR detection only, without an RF transmission, for 1 minute. Allowing you to walk around
and check the PIR coverage area & sensitivity.
BATTERY TYPE
A 3-volt lithium battery powers the unit.
The battery provides about 3 years of continuous
operation (depending on the amount of activity).
If the battery reaches a factory preset low level, a
LOW BATTERY signal will be sent. From this
moment, the detector remains operational for
another 30 days giving enough time to replace
the battery.
BATTERY INSTALLATION
CEILING INSTALLATION
1. Remove the front cover.
2. Take out the old battery.
3. Be sure to insert the battery correctly with
the PLUS terminal of the battery to the
right-hand side.
The battery must be replaced
by a 3 volt lithium battery
