Access Control Module
6–2 iSTAR Ultra Installation and Configuration Guide
Access Control Module
The ACM provides Readers, Inputs and Outputs used in access control. An iSTAR Ultra
contains either one or two ACMs.
Figure 6-1 on page 6-3, Figure 6-2 on page 6-4, and Figure 6-3 on page 6-5 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 6-1 on page 6-3 indicates the eight basic sections of the ACM.
