Programming
8.1. Application setting (Fig. 1, item K)
The specified operating radius applies to an attack with an oxygen lance. If
attacked with a mechanical tool (e.g. a drill) the value may be as much as
three times higher. The specified operating radius is a guideline which is
heavily influenced by the characteristics of the material and the type of
construction.
Select the material type for the protected space and the required detection
radius by selecting the DIP switch options as follows:
Operating

There are 3 settings selectable via the DIP switch (Fig. 1, item K), to
enable the USER MODE selectable settings through the GMSW7
SensTool software. DIP switches 1 & 2 must be in the ON position to
establish communications between the PC and the detector.
8.2. Sensitivity (Fig. 6, terminal 7)
When this input is active, the sensitivity of the detector is reduced.
The sensitivity input should only be applied under special
circumstances, and only for short periods of time. Any reduction in
sensitivity must comply with applicable regulations such as VdS in
Germany. The factory setting is Active low, Active high is
selectable through the GMSW7 SensTool software.
Sensitivity is reduced to 12.5% of the original setting for the duration of the
remote signal. A potential application is the prevention of alarm triggering
where loud functional noises prevail.
8.3. Test input (Fig. 6, terminal 4)
The GMXS1 internal test transmitter (Fig. 1, item J) is activated by the
application of a low signal into the test input terminal. If the detector is
functioning correctly, the detector will trigger an alarm (trigger time <3s).
The factory setting is Active low. Active high is selectable through the
GMSW7 SensTool software.
Active low = 0 V applied to activate.
Active high = 0 V removed to activate.
9.
LED display
The red LED (Fig. 1, item E) pulses during initialisation. In the event of an
alarm, the LED illuminates for approximately 2.5 seconds. This LED is only
visible when the cover of the detector is removed.
10. Commissioning
1.
Apply the supply voltage.
The LED (Fig. 1, item E) pulses for 10 seconds.
2.
Leave the detector for a further 20 seconds.
The detector is now operational.
3.
Verify the correct radius and material type have been selected by
the DIP switches or the GMSW7 SensTool software.
If SensTool is not available, then using a multimeter (Ri ≥ 20 kΩ) at
terminal 1 (0 V) and at the test point (Fig. 1, item D) to monitor for the
analogue integration signal:
Quiescent level
Integration start
Alarm threshold (w/o load)
4.
Check for interference using the SensTool > Analyse option.
The Digital Filter setting in the Settings tab may assist in
reducing inherent interference. For additional information, please
refer to the SensTool software and the associated manual.
10.1. Functional checks
Functional checks can be performed as follows
With the cover removed, scratch the metal case of the detector with a
screw driver until the LED (Fig. 1, item E) confirms an alarm.
Apply the required input to terminal 4 to activate the GMXS1 internal
test transmitter, if provided.
Apply the required input to activate the GMXS5 external test transmit-
ter (Fig. 7), if provided.
Simulate an attack on the protected space.
Carefully replace the cover and secure it in place.
11. Service
The function of the detector and its mounting should be checked at least
once a year, as follows:
Functionally test the detector as detailed in section 10.1.
Verify the settings of the detector by the DIP switches or by the
GMSW7 SensTool software.
Check the mounting of the detector to ensure that the detector is se-
curely attached.

Check that there is a direct connection between the detector and the
mounting surface. Paint, varnish, dirt, silicone or similar materials will
impede the acoustics.
Refer to local approvals for guidance on this matter.
12. Modular vaults
The following principles must be strictly observed when using seismic de-
tectors on modular vaults made from steel or concrete.
Thickness from 100 to 400mm
Width up to 1000mm
Length up to 6500mm
Modules with detector arrangement
1 2 3 4 5 1 2 3 4 5 . . . .
Corner joints between walls seamlessly welded Always 1 detector on
Strict compliance with the following principles is vital when using seismic
detectors on modular vaults made from steel and concrete:
1.
One detector for a maximum of 5 wall modules. The detector must be
mounted on the middle module.
2.
In addition to being bolted together, all of the joints between the
modules must be welded every 400 − 500mm with a 30 − 40mm
seam.
3.
Corner joints between wall modules must be seamlessly welded if the
coverage area is to extend beyond the corners.
4.
In the case of wall modules equipped with detectors, the immediately
adjoining floor and/or ceiling modules can be included in the
coverage area if the corresponding butt joints are seamlessly welded.
5.
Where building vaults use modules of varying thickness, the butt
joints must be seamlessly welded.
6.
Avoid mounting detectors on modules to which guide rails for
cassette transport lifts, ventilators or other mechanical equipment are
attached.
7.
Always equip modules which have a pay-in/withdrawal slot with a
detector. The detector can monitor the adjacent modules.
8.
All doors must be equipped with a detector.
