Power Requirements
iSTAR Ultra Installation and Configuration Guide 4–5
Circuit Breakers need to be sized so that its normal sourced current does not exceed 80% of
the circuit breaker rating.
This device must be suitably rated for the installation; see electrical ratings guidance.
The conductor size for the inputs must be selected based on the rating of their
corresponding over-current device and in accordance with local and national regulations.
Heat Dissipation
Table 4-4 on page 4-5 lists the heat dissipation for the Rack and Wall mount configurations.
FOR BURGLAR ALARM INSTALLATIONS:
The iSTAR Ultra is not provided with backup power. An external
power supply must be provided with the following characteristics:
• UL 603 or UL 294 Listed
• Minimum four hours of standby power
Tyco / Software House Advanced Power Supply (apS) meets these
requirements. Several apS units, wired in parallel, will provide 12Vdc
output at [units x 3.75A] in excess of four hours when using the
supplied 17AH batteries.
All Burglar Alarm and Intrusion Zone inputs must be supervised and
have Triggers configured to Alarm upon Tamper.
At least one RM2L-4000 reader must be in each area/partition for
signal acknowledgement
There are multiple power inputs to the unit. To completely
de-energise the unit, disconnect ALL power sources.
NOTE
For UL Listed products, a UL 603 or UL 294 listed power supply must be
used.
