structure's ability to transmit vibrations, etc. Note that the
universal sensor can be mounted on a horizontal plane
e.g. on a flat ceiling or under a door lintel.
2. Remove the detector cover and secure the baseplate to
the structure either vertically or horizontally as required.
3. Orientate the sensor module so that the ARITECH logo is
upright and in the readable position (see Figure 1).
4. Route cabling into the unit and wiring the unit as shown in
Figure 2.
5. Ensure that the screws of the sensor module (see
Figure 1, item 1) are secure.
6. When all sensors in the system are fully wired, disable
(Figure 2, item 8) or enable (Figure 3, item 8) the dual loop
resistors with jumper J2.
7. Set the appropriate control voltage (CV) for the latch and
LED enable input of the device with jumper J1 (Figures 2
and 3, item 2).
8. Apply power to the system. The alarm relay and the LED
of each unit are activated for a period of four seconds.
9. Program each unit for gross attack and pulse count.
10. Place the cover and secure it with the screw.
Dual loop selection
When the GS620N is used together with a UTC Fire & Security
control panel, the dual loop option can be selected. In this
configuration the alarm loop and the tamper loop are combined
into one loop using 4.7 kΩ resistors. The dual loop option can
be selected with jumper J2. If J2 is placed, the dual loop is
selected.
See Figure 3, item 5, for contact configuration in dual loop
mode.
Remove J2 in standard applications.
Control voltage selection (CV)
The detector can be remote controlled via the latch and LED
enable inputs. The control voltage (CV) of these inputs can be
selected with the polarity jumper J1 (Figures 2 and 3, item 2).
When jumper J1 is placed, the control voltage is set to 12 V.
Removing jumper J1 sets the control voltage to 0 V.
When the control voltage is applied to an input, this input is
activated.
LED enable/disable
For test purposes the LED of the device can be enabled via the
LED enable input. Activating the input enables the LED.
The latch input must not be activated to enable the LED
indication for testing!
Gross attack and pulse count programming
1. Enable the LED indication by activating the LED enable
input. This allows the LED to light up during programming.
2. To calibrate the unit for gross attack, set both the switches
1 and 2 to ON. In this position the pulse count circuit is
2 / 18
disabled. In this setting the relay can only be activated by
a gross attack.
3. The LED will light up for one second every time the sensor
detects a shock. An alarm event (relay trip) indication is
given when the LED remains lit for approximately
4 seconds.
4. When the gross attack level required for activating the
alarm has been set, select the pulse count required for
alarm activation with the switches 1 and 2. See Table 1
below for pulse count setting.
5. Using the gross attack switches 3 and 4 for sensitivity
adjustment, apply high level shocks to the structure, using
the LED as a guide to when the alarm relay trips (LED on
for four seconds). See Table 2 below for the position of
switch 3 and 4 for each gross attack level.
Note: Pulse count signals are counted at one-second
intervals and stored in a 30-seconds digital memory.
These small signals detect an intruder gently prising open
a window or doorframe etc.
6. To test the pulse count setting, create small shocks on the
structure below the gross attack level. Each time a shock
is detected and registered in memory, the LED will light up
for one second. When the programmed pulse count is
reached, the alarm relay will trip, which is indicated by the
LED remaining on for 4 seconds. If the pulse count isn't
reached within 30 seconds or the alarm relay trips, the
stored pulses are cancelled. After cancellation a new
detected pulse starts a new 30-second memory time.
Note: If only gross attack level activation is required, set
both switches 1 and 2 to ON.
7. Deactivate the LED enable input after programming gross
attack and pulse count. This ensures that the LED does
not light. Therefore window cleaners etc. cannot see the
sensitivity level or the area covered.

Alarm memory
The GS620N can latch alarm events into memory. The
memory function can be enabled by the latch input.
When the system is armed, the latch input of the detector
should be activated (apply CV to input). The latch terminal is
normally connected to the latch or arm/disarm terminal of the
control panel (see Figure 2). Select the appropriate control
voltage with jumper J2. Activation of the latch input resets the
