discussion assumes familiarity with the Inertia Crossbar System ICS and its functions For those fully acquainted with the system operation reading the applicable ICS Installation Instructions is recom used with the Inertia Crossbar System and the system Burglar Alarm Control the No 979 is capable of initializing the ICS The No 979 eliminates the need for manually resetting the system components to arming the control The N 979 reports ICS system alanns to the control panel and provides a warning if is a system fault during arming the No 979 installed arming the Burglar Ajarrn Control will cause the No 979 to electronically reset all and Monitors in the Inertia Crossbar System any Analyzer or Monitor connected to the system is permanently faulted in alarm when the Burglar Alarm Con is armed the No 979 does not report an alarm immediately but instead produces a voltage output signal at BUZLER OUT terminal This output which lasts approximately 10 seconds can be used to drive the buzzer ter on Controls so equipped The buzzer should be so located that its sound is audible to the subscriber when arms the system the Burglar Alarm Control is disarmed durin this 10 second warning period no alarm is reported by the No 979 subscriber must then correct the cause o B the fault before the system can be m armed If the user ignores the and fails to disarm the Burglar control within the 10 second period the No 979 reports an alarm to the Alarm Control AND WIRING No 979 is installed within the System control panel After the unit is mounted in place the wiring connec are made Preliminary considerations teninal and jumper functions and installation and wiring prcb are given below Considerations of the No 979 in a burglar alarm system requires that the arm disarm status of the system be known by the 979 This information is sent via a control lead from the control panel A signal of either polarity may represent system status Depending on the polarity chosen it may be necessary to cut a jumper on the No 979 This is in the Jumper paragraph below the No 979 on any convenient edge in the control panel cabinet See Diagram 1 installing wiring for No 979 disconnect AC and battery from control panel Connect the control voltage lead from the particular control panel being used as shown in Diagram 2 Make remaining connections 2s shown in Diagram 3 Functions See Diagram 3 1 2 Arm

WHITE Jumper Cut for positive control voltage Leave intact for low control terminal at each ICS 3 shows the interconnection of various ICS components with Tamper connections omitted for simplicity switches can be connected in a separate Loop or as a part of the Inertia Crossbar System loop in the Installation Instructions accompanying each ICS Analyzer and Monitor addition of the No 979 Interface Module has no effect on the Tamper loop wiring in those cases where Tamper loop connections are used When Tamper switch wiring is interconnected with other ICS corn the Tamper switches should be connected in series with the CHECKOUT functions and operation of the No 979 can be checked out in the manner described below Since some of the involve deliberately setting off an alan is advisable to contact any central alarm station connected the system and inform its personnel of your intentions sure that the alarm system is ready for arming and there are no disturbances near any of the system the Burglar Alarm system in the usual manner The warning buzzer if employed should be silent the Burglar Alarm system and proceed to djsturb at least one ICS sensor It should respond in the nor manner the system After 10 seconds disturb one of the sensors The system should go into an immediate the No 979 Buzzer and alarm outputs Disconnect a sensor wire This should cause a constant state of When the associated Monitor or Analyzer LED lights steadily indicating success of this attempt the Burglar Alarm system The buzzer if connected should sound for approximately 10 seconds after an alarm should occur If the Control is disarmed before the buzzer turns off no alarm takes place the system The disturbed sensor and its associated Analyzer or Monitor should be evidenced on latch type devices by its illuminated LED Correct the disturbance and thsn disarm the systqm to restore the No 979 to its normal state TO TELL THE SUBSCRIBER pertaining to the use of the system should be properly conveyed to the customer in order to eliminate and possible misunderstandings resulting in false alarms In particular the customer should know the Arming the entire system is done via the Burglar Alarm Control arming function Successful arming is in by the absence of buaer annunciation If any Monitor or Analyzer senses permanent fault at arming time the system buner sounds for a prolonged The system must be disarmed within 10 seconds to prevent alarm reporting The disturbed sensor should be located by inspecting each sensor monitor or analyzer for an LED indication When all disturbances are cleared the system can be rearmed and the premises secured SPECiFiCATiONS Voltage Voltage Output Contacts Current 6 to 14V DC from an appropriate control or 6 to 12V DC nominal Either polarity can be used If disarmed low is used cut WHlTE on No 979 plus cur
