Mechanical Security
The system provides the necessary circuitry to interface eight mechanical security
switches.
Up to eight of the mechanical security inputs can be used for security breach
detection while the power is off (independent channel 0 and 1-7 detection). When the
power is on, a random number is written to a battery-backed register on the Driver
Board (channel 0
−
logic door only). A breach of security (opening of the switch)
while the power is off causes the register to reset. When the power is restored the
absence of the original number indicates a security breach. If a changeover switch is
used, the closing of the normally open contact will also reset the register.
The mechanical security sensor interface has the following specification:
•
Switch type: Single pole, changeover
•
Secure state: normally closed
•
Driving source: 3.3 V DC.
