Installation Requirements
iSTAR eX Installation and Configuration Guide 3–5
Power Requirements (Standard Power Supply and NPS Models)
The standard iSTAR eX uses the UL Recognized ESD Power Supply, Model
SPS-6.5 with Battery charger. The NPS version uses a UL Listed 603 External
Power Supply, such as the Software House apS.
To ensure adequate power, calculate the total power requirements of iSTAR
eX and its related hardware, as follows.
Add the total current power for components in the system (modules,
relays, optional modules, readers, and wire resistance).
Use the information in Tables 3.3 through 3.8 to compute the current draw
of components attached to iSTAR eX.
The standard iSTAR eX must be connected to a 15A circuit breaker protected
branch circuit. Cabling must be UL Listed. See the section “Connecting AC
Power to UL Recognized ESD Power Supply” on page 4-12.
iSTAR eX Components and Boards
Table 3.3 shows the power requirements of iSTAR eX components and
attached boards.
a
RM-4 board has only been evqaluated by UL with RM Series readers (RM 1,2,3)
b
RM-4E boards have only been evaluated by UL for use with RM-DCM-2 enclosure.
Table 3.3: Component and Board Power Requirements
Component/Board Current Draw at 12VDC
iSTAR eX - GCM and PMB 500 mA with LCD - no load
iSTAR eX GCM board 350 mA with LCD - no load
iSTAR eX PMB board 150 mA - no load
RM-4 board
a
80 mA without LCD - no load
180 mA with LCD - no load
RM-4E board
b
125 mA - no load
I/8 board 125 mA - no load
R/8 board 150 mA - no active relays.
Add 20 mA for each active relay
