Operator Controls and Indicators Control or indicators Function Operating mode switch Selects the Control Unit operating mode (ACCESS, (key-operated, 3-position TEST/RESET, SECURE). rotary) AC POWER (indication lamp) Illuminated when ac power is applied to unit. Audible signal device Sounds when the operating mode switch is at TEST/ RESET and a duress, intrusion, or tamper alarm is received at the Control Unit. b. There is an adjustable alarm delay to allow access if the CU is within the secure area. Enter the area and insert key in mode switch lock. Turn switch to TEST/RESET and then to ACCESS before the end of the alarm delay or an alarm will be initiated. To leave the secure area, turn mode switch to TEST/ RESET or ACCESS and then to SE-CURE. Remove key and leave area be-fore the end of the alarm delay or an alarm will be initiated. c. After responding to an alarm, reset the CU, to a no-alarm condition. To reset CU, turn mode switch to TEST/RESET, and then to SECURE. Remove key and leave area before the end of the alarm delay or an alarm will be initiated. 2-3. EMERGENCY OPERATION. Operation with incomplete surveillance coverage or faulty tamper circuit should be held to a minimum. Extended periods of operation on battery (stand-by) power should be avoided. 2-4. UNUSUAL OPERATING CONDITIONS. Loss of synchronization between Data Transmitter and Data Receiver may occur while operating during heavy thunderstorms. Section II. THEORY OF OPERATION 2-5. FUNCTIONAL DESCRIPTION. The Control Unit is the central element of J-SIIDS. Its primary function is to monitor continuously the status of the secure area. It does this by processing signals from a duress alarm and five, or fewer, intrusion detection sensors located in the secure area. This status information is processed and transmitted to peripheral monitoring equipment. The Control Unit also provides primary and emergency standby power to its associated sensors; provides Secure, Access, and Test/Reset modes of system operation within the secure area; and maintains secure area subsystem security by monitoring sensor and audible alarm signal lines and antitamper control of its own enclosure.
