4U iSTAR Pro as a Burglar Alarm System Unit

AC Power Fail Alarm
To transmit the AC Fail alarm signal from the UPS to the Rack Mount iSTAR
Pro unit, wire a two-wire circuit from the designated UPS alarm relay contacts
into a selected supervised input on the rear of the Rack Mount iSTAR Pro, using
two 1K resistors for line supervision. Input number 16 is recommended for this
purpose. Follow the wiring diagram below:
FIGURE 32. Power Fail wiring
Once wired, configure Input #16 in the C•CURE 800 or C•CURE 9000 host as a
Normally Open Supervised Input. Then, configure the input to trigger an Event
in the system, with the event set up to always be armed, on-line, annunciated,
and require acknowledgement. The Event should have an appropriate name,
such as “AC Power Fail.” In addition, the event should be configured to activate
2 Outputs which are wired to an external audible sounder and LED indicator,
installed near the keypad reader used to arm/disarm the Intrusion Zone. This
allows the AC Power Fail notification to be presented both at the Monitoring
Station and locally at the Intrusion Zone reader.
NOTE
The resistor wiring is for NO (Normally Open) although the connection is to the
NC output of the apS/UPS. The reason is that in the normal mode (power ON) the
relay is activated and the circuit is open. When the power fails, the relay loses
power and deactivates, which results in an alarm (closed circuit).
Installation and Wiring
of Supervisory /
Monitor Points
Supervisory input points must be used for UL 1076 applications. The iSTAR Pro
rack Mount provides either 16 or 32 supervised inputs, depending on the model
purchased. Each supervised input must be configured to trigger an event when
the input is activated or a supervision error is detected.. These events must be
configured to always be armed, on-line, annunciated, and require
acknowledgement.
Each monitor point functions independently and does not interfere with the
operation of other monitor points. The hardware modules monitor the
supervised inputs. The following states are reported: Secure, Alert, Shorted,
Open, and Line Fault
