bus
The GM 570 LSN seismic detector is suitable for monitoring
armored cabinets, cash boxes, automatic teller machines,
strong rooms, night safes, modular vaults, and vault walls
for all known burglary tools such as diamond-tipped drills,
hydraulic rams, oxygen lances and explosives.
Functions
The seismic detector is suitable for monitoring armored
cabinets, cash boxes, automatic teller machines, night
safes, armored safes, and safe vault walls for all known
burglary tools such as diamond-tipped drills, hydraulic
rams, oxygen lances and explosives.
The GM 570 LSN is fitted with a double housing. This design
gives the detector good protection against electromagnetic
influences and from deliberate or accidental damage.
Mechanical vibrations caused by a burglary attempt are
detected and analyzed by the seismic detector sensor, and
an alarm is triggered.
Temporary reduction in sensitivity
To prevent false alarms caused by loud operational noises,
e.g. use of the object intake mechanism on day/night vaults,
the response sensitivity of the detector can be temporarily
reduced to approx. 1/8 of the pre-set value via a control
input (e.g. contact switch on the object intake mechanism).
Note When reducing sensitivity, compliance with the
relevant VdS regulations within the context of
the system must be checked and accepted by
VdS.
GMXS1 test transmitter (optional)
The GMXS1 test transmitter is a component of the test
system for the GM 570 LSN seismic detector. Installing the
test transmitter allows the seismic conductibility of the
mechanical mountings to be checked along with the
functionality of the electronics.
