Access Control Module
The ACM provides Readers, Inputs and Outputs used in access control. An iSTAR Ultra
contains either one or two ACMs.
Figure 5-1 on page 5-3 , Figure 5-2 on page 5-4 , and Figure 5-3 on page 5-5 show ACM
components, switches, and LEDs.
The ACM has eight different sections that contain all of the components needed for a Door as
indicated below:

RS-485 Port for an RM Bus or other generic RS-485 Reader.
• Termination switch for the RS-485 Port

Direct Connect Wiegand Port with LED and Beep drives. This is for ‘Wiegand signaling’
devices that communicate using Data 1 and Data 0.

AUX Port to power devices such as a PIR or Motion Sensor

FAI Activate Switch (Only for Primary Relay)

Two Relays - One Primary and one Secondary
• Primary Relays (Field replaceable - mounted in a socket)
– Physically larger than the secondary relays
– 8 per ACM
– Can be Wet or Dry (Wet powered by either LOCK 1 or 2)
– Can be used for FAI
– Dry Rating 5 Amps @ 30 Vdc or 30 Vac
– Wet Rating 0.75 Amps @ 12 Vdc
– Form C
• Secondary Relay (permanently soldered)
– 8 per ACM
– Can be Wet or Dry (Wet powered by either VLOCK 1 or 2)
– Cannot be used by FAI
– Dry Rating 1 Amp @ 30 Vdc or 30 Vac
– Wet Rating 0.75 Amps @ 30 Vdc
– Form C

Jumper for each relay to select Wet / Dry and Wet power source
It is convenient to configure a Door with all the components together in one of these sections,
but it is not a requirement. However, all door components must come from the same
controller.
Figure 5-1 on page 5-3 indicates the eight basic sections of the ACM.
