1.6 Tamper protection
C.A.S. has different methods of protection to prevent the system from being
tampered with.
1. Stray-field protection on the wireless magnetic contacts and the cable loops
When the system is activated and the contact is closed, if another
magnet approaches (to bypass the contact) the main alarm is
activated immediately.
2. Interference signal detection
If the transmitter frequency of the system is superimposed by
a radio signal, the LEDs are activated after 5 seconds and the
siren sounds after 15 seconds.
Once a GSM/GPS module has been connected, an SMS with
“interference signal” is transmitted after 5 seconds.
3. Voltage tampering
If the supply voltage is interrupted for more than 10 seconds when the
system is activated, a pre-alarm (a series of short tones) sounds and
after 20 seconds, the main alarm* is activated (siren and LEDs).
Once a GSM/GPS module has been connected, an SMS with
“tamper voltage” is transmitted after 5 seconds.
*depending on the setting on the program selector switch
4. Tampering with the casing cover
If the casing cover is opened when the system is activated,
the main alarm sounds immediately.
Once a GSM/GPS module has been connected,
an SMS with “tamper” is transmitted.
