1.
Via the AM output to a suitable input on the control panel. If
voltage free contacts are required then the AM output can drive
a suitable relay module (e.g. the RL1 module) and the relay
contacts connected to a suitable loop in the control panel (see
modes 1,2,3 and 4 below).

Via the Alarm relay (see modes 2, 3 and 4 below)
7.5.2 Anti Mask Modes
The effect of a mask condition on the AM output and Alarm relay
depends on the AM mode selected on DIL switches 6 and 7.

AM Mode 1 When a mask condition has been detected, the AM
output will switch OFF for approximately the duration of
the mask condition plus 15 seconds and will then return
to the ON state.
AM Mode 2 When a mask condition has been detected, the AM
output will switch OFF AND the alarm relay will de-
energise for approximately the duration of the mask
condition plus 15 seconds and will then return to the
ON state.
AM Mode 3 When a mask condition has been detected, the AM
output will switch OFF AND the alarm relay will
de-energise. The mask condition is now latched. The
latch can be reset by a successful walk test alarm after
approximately one minute from the end of the mask
condition.
enable DIL switch 1 set to (1). This operation can be checked by
following the procedure below:
- Ensure that the sensor is in UNSET mode and the TEST input is
low.
- The RED LED should not light with movement in front of the
sensor.
- Remotely enable the RED LED by applying a positive control
voltage to the TEST terminal.
- The RED LED will now illuminate with movement in front of the
sensor.
- Remove the control voltage from the TEST input.
7.4
Beamfind Mode
Beamfind mode is used in walk testing to determine the coverage of the
detection zones. In this mode the RED LED will give a short flash when
the target enters or exits a detection beam.
To use Beamfind mode when L-Type latching has been selected, the
sensor should be in Unset mode or the TEST input high, with the LED
enabled (0) and the Beamfind mode set to (1) on the DIL switch.
Beamfind mode used with F-Type latching requires the TEST input to
be high or the LED to be enabled (0) and Beamfind mode selected (1).
7.5 Anti-Mask Models
7.5.1 Signalling to Control Panels
Anti-Mask signalling can be carried out by either of the following
two methods :
