Optional Hardware Modules
Table 1.3 describes hardware modules that communicate with iSTAR eX.
NOTE
The RM-4, RM-4e, and ARM-1 have not been evaluated by UL for use with
iSTAR eX.
Table 1.3: Optional Hardware Modules
Module Description
RM-4 and RM-4E The RM-4 and RM-4E are printed circuit boards that provide the
hardware interface between either a Wiegand or magnetic
signaling reader and apC or iSTAR/iSTAR eX hardware. The RM-4
and RM-4E also provide the inputs and outputs that communicate
between door components and apC or iSTAR hardware.
I/8 Module The optional I/8 Module provides eight additional Class A
supervised inputs. An I/8 Module must be installed in an RM-DCM-
I8 or RM-CAN enclosure up to 4000 feet (1212 meters) from the
iSTAR eX controller and wired via an RS-485 bus connection. The
I/8 Module power requirement is 125 mA at 12 VDC.
R/8 Module The optional R/8 Module provides eight additional relay outputs. An
R/8 Module must be installed in an RM-DCM-R8, or RM-CAN
enclosure up to 4000 feet (1212 meters) from the iSTAR eX
controller and wired via an RS-485 bus connection.
The R/8 Module power requirement is 125 mA at 12 VDC plus 20
mA per active relay (for a maximum of 285 mA per module).
The relays are rated at 30 V, 2 A.
ARM-1 (Auxiliary
Relay Module)
a
a. The ARM-1 module has not been evaluated by UL.
The optional ARM-1 reduces wire runs back to iSTAR eX. The
ARM-1 provides a relay output for a door strike or other equipment
located near a standard style RM Series Reader module. The
relays are rated at 30 V, Resistive 5.0A, Inductive 2.5 A. The ARM-
1 may be installed up to 25 feet (7.6 meters) from the RM-4
module.
Note: RM-4E boards provide on-board relays, and do not
require an ARM-1
