QUORUM - QU-004 Cabinet Guard - Cabinet Guard Alarm - Key Operated

Cabinet Guard Alarm - Attention Moms! We think it's the most efficient alarm for keeping Children away from Dangerous Chemicals because it can not be turned off without a key. ". . . designed to provide reliable security for cabinets, especially those containing firearms, hazardous materials or other materials with restricted useage." Actually better made than most alarms coming from our friends in China. KEY OPERATED (Two provided) When the unit is turned to the ON position, the alarm will be triggered automatically when the magic sensor is moved away from the control - Once the sensor has been triggered it can only be disarmed using one of the keys. The PZT alarm is Not as loud PAAL alarms but noticeable. If you want to attract a LOT of attention use the PAAL. Low battery Indicator (9V batttery not included) and Sensor Bar. Finely printed instructions in 4 (Four!) languages.

Great for liquor, medicine cabinets, firewarms and/or refrigerator.  

When activated, alarm emits a loud siren sound alerting you of entry.

Only the key can turn off the alarm.

Tower Piezo Switch Development - G23NNYA-42408 - Switch, Piezo.

A piezo switch is an electrical switch based on the Piezoelectric Effect. The charge generated by the piezoelectric element in the switch is typically used to turn on an integrated semiconductor device such as a field effect transistor (FET), causing the switch assembly's output to be active, or "on". When the FET is on, current can flow through it as with a conventional metal contact-based switch. After the voltage pulse is dissipated in the gate resistor, the FET turns back "off", its normal high impedance state. The Piezoelectric Effect uses the fact that force applied to certain materials causes stresses that generate this electric charge. In the case of piezo switches, the force could be compressive pressure that causes the (typically disc-shaped) piezo element to bend very slightly like a drumhead.
