Alarm ? vibration sensors
Designed for the lock (with a view to issuing signals «Alarm») of building structures of buildings and structures by the dynamic effects causing their destruction (walls, doors, floors, safes, etc.).
By the principle of work are:
pezodatchiki (working on direct pezoeffekte: if there is strain on the electrodes piezoelement a potential); induction sensors (working on the properties of electromagnetic induction). Dining detectors being the DC voltage in the range of 10 to 15 volts separate cables (cable) from the receiving-control instruments, or an independent (separate) source.
