Red LED ON.
Accu-Trak
Green LED flashes for microwave;

Supervision Red LED flashes for PIR failure;
Failure
Green LED flashes for microwave failure.
Note: When Accu-Trak environmental test mode is selected,
alarm relay is constantly held open to prevent leaving the
detector in the test mode.
SIGNAL PROCESSING OPTION
For Standard Signal Processing, set DIP Switch #2 OFF. For
Intermediate Signal Processing, set DIP Switch #2 ON. Use a
small pointed tool to move the switch handle.
Standard Signal Processing: This is the recommended
setting for maximum false alarm immunity. It tolerates
environmental extremes on this setting.
Note: Standard Signal Processing is recommended for
installations with pets.
Intermediate Signal Processing: This is the recommended
setting for any location where an intruder is expected to cover
only a small portion of the protected area. It tolerates normal
environments on this setting.

TEST PROCEDURES
On power-up, testing must not begin until the LED
extinguishes after first applying power to signify warm-up is
complete, about 50 seconds. If the LED begins to flash at a
constant rate, refer to the section on SUPERVISION.
Note: During this warm-up period, the relay will be held
CLOSED.
Accu-Trak Environmental Test Mode: ADEMCO's unique
Accu-Trak environmental test feature easily provides an
environmental check for potential false alarm sources for both
the PIR and microwave channels. Simply set DIP Switch #1
to ON. Information for both channels is simultaneously
viewable on the two LEDs, providing crisp, immediate
feedback (see below).
The alarm relay remains continuously open when the test
mode is selected to prevent leaving the detector in this
environmental test mode.

COLOR
PIR
RED
LED flashes when potential false alarm
source is detected, such as fans or
heating duct.
Microwave GREEN LED is ON when potential false alarm
source is detected, such as a fan or
mylar balloon.
Important:
Because of the advanced C
mode should NOT be used to verify coverage of the
detector. Detection coverage can only be verified by Walk-
Testing in the normal operating mode (DIP Switch #1 set
to OFF).
Testing in Normal Operating Mode:
the unique Walk-Test mode, the detector should be tested in
the Normal Operating Mode with the following steps:
1. Remove the front cover and ensure that DIP Switch #1 is
set to OFF for Normal Operating Mode.
2. Set DIP Switch #2 to the Pulse Processing Option that will
be used for this installation.
3. Enable the LED by setting DIP Switch #3 OFF.
4. Replace the front cover and walk through the protective
zones, observing that the detector's red LED lights
whenever motion is detected. If necessary, re-adjust the
microwave sensitivity to the minimum level required for
satisfactory detection and repeat the Walk-Test.
Note: The relay will open when the LED lights.
5. After Walk-Testing is complete, the LED may be disabled,
if desired (DIP Switch #3 ON).
SUPERVISION
This motion sensor is equipped with advanced supervision of both
the PIR and microwave channels. If a microwave channel failure
occurs, the sensor will continue to operate as a dual-element PIR
sensor in Standard Signal Processing mode regardless of the
processing option chosen. Even though some operation is
maintained, the unit should be replaced as soon as possible. If a
PIR failure occurs, the unit becomes non-operational.
