The external security operating unit consists of a solid die cast housing. The top part of the housing has an electro-mechanical unit for monitoring against drilling. This prevents all forms of unauthorised access to the electronics built into the device. In addition, mechanical tear-off protection and cover monitoring are provided. The "ON / OFF" positions of the key are detected by micro switches. The integrated buzzer and two-colour LED (red / green) are actuated by acknowledgement signals sent by the connected intrusion detection control unit (logic-circuit).
