loop impedance is 4.7 kΩ. For a detector
alarm, the alarm relay contact opens and
the impedance of the dual loop increases
to 9.4 kΩ, indicating an alarm. When the
detector housing is opened, the tamper
circuit opens and the dual loop is
interrupted, indicating a tamper alarm.
Terminals 4 and 5 are linked.
Zone inputs of the control panel are
connected to terminals 4 and 7.
Terminals 3 and 6 are not used.

* Factory default
DIP switch 1: Polarity of control voltage (CV)
On: "Active high" provides the standard logic with
"Active high" logic to enable walk test and day/night
inputs.
Off: "Active low" provides "Active low" logic to
enable walk test and day/night inputs.
DIP switch 2: Chime
See Figure 12.
The detector can distinguish the direction of the
intruder during daytime. Disable this option by
setting the detector to chime OFF. When the chime
is ON, the detector will trigger an alarm when the
intruder moves right-to-left or left-to-right across the
curtains.
Note:
If the day/night terminal is not used and the
chime is ON, the chime will be ON both during
disarm and arm (day/night) mode.
DIP switch 3: Chime direction
See Figure 13.
On: Alarm when an intruder walks from left-to-right.
8 / 80
Off: Alarm when an intruder walks from right-to-left.
Stand with your back to the detector to determine
left and right directions.
DIP switch 4: LEDs
On: Enables both LEDs on the detector at all times.
Off: Puts both LEDs under the control of walk test
and day/night input.

DIP Switch 1: When to signal AM (anti-masking)
or TF (technical fault) output
On: Signals AM or TF only when the system is in
day mode. EN 50131-2-2 compliant.
Off: Always signal AM or TF.
Note:
following DIP switch settings are recommended:
1: On, 2: Off, 3: Off, 4: Off
AM alarms are now only signaled to the control
panel during day mode by the AM relay. The LEDs
are controlled by day/night and walk test inputs.
Resetting the AM alarm can only be done in walk
test mode.
Never show the detector state to the intruder via
the LEDs.
