DV1201 FOCUS-VVS Vault and Safe Vibration Sensor (7187-131, Lot 2)
Used in reverberant or nonreverberant vaults, each sensor has a protection radius of 13’ (4m) on poured
concrete or steel, 6-1/2' (2m) on concrete block, or 3-1/4' (1m) on brick. It can be mounted on wall, floor,
or ceiling. A minimum of three per vault is required to detect structurally borne vibration associated
with penetration attempts by thermic lance, mechanical tools, or explosives. Sensor is enclosed in beige
aluminum cover, and includes cover/pry-off tamper, sensitivity/ambient-noise test point, sensitivity
adjust screw, and terminal strip. Supplied with aluminum mounting plate, all mounting hardware, and
an 880353 Cosmotron VVT-305 Remote Test Oscillator. The remote test oscillator can be powered from
the same SIM used to supervise the alarm contacts. Use 806399 Protection Box to protect the detector
in severe environments. Use a Cosmotron VVM-302 Recess Mounting Box (FB) when the detector is
mounted in a concrete wall.
A minimum of two per safe are required (minimum of three if safe has two doors) to detect structurally
borne vibration associated with penetration attempts. Each sensor has maximum protection radius of
12' (3.6m) when used on an all-steel safe at least 1” (24.4mm) thick or on a concrete-clad safe at least 6"
(152.4mm) thick and free of cracks or seals. May be mounted outside or inside safe. Refer to technical
bulletin T-7187-131 for additional details.

472375 Power Supply Module
The module comes with terminals for connecting an input transformer, for connecting a battery, for
12VDC output power connections, and for connecting a SIM or PID to supervise the application of AC
power. The power supply output rating is 1.5A when using the 50VA input transformer and is 2.5A
when using the 82VA input transformer.
