Description
Piezoelectric sensor for detecting vibrations and shocks.
Thanks to the use of the most advanced CMOS technologies, the 447 series sensors offer greater immunity from false alarms. The particularly robust structure with no moving parts is independent of the force of gravity, thus allowing installation in any position on a flat surface.
All models have an LED memory indicator which can be reset by the control panel or left on as a deterrent. Sensitivity is controlled by a double-range variable potentiometer to offer precise adjustment.
Available with or without magnetic contact, in white or brown.
• Container material: Thermoplastic
• Color: white or brown.
• Operation: Piezoelectric sensor with NC relay output. In the version with contact a reed bulb is applied in series to the piezoelectric to signal not only the vibration but also the opening of a door. Can be installed on safes or fixtures.
• Connection type: Terminals (2 for contact - 2 for tamper - 2 for power supply - 1 for remote control - 1 for the First to Alarm bus line)
• Operating temperature: -10°C ÷ +50°C
• Degree of protection: IP 40
• Standard equipment: Fixing screws.
• Version: IP 65 cable gland
• Dimensions: 85 x 23 x 25 mm.
Mod. CSA447B
