Access Control Module
The ACM provides Readers, Inputs and Outputs used in access control. An
iSTAR Ultra contains either one or two ACMs. 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 RS-485 Reader.
Terminator switch for the RS-485 Port
Direct Connect Wiegand Port with LED drives. This is for ‘Wiegand signaling’
devices that communicate using data 1 and data 0.
AUX Port to power devices such as a PIR
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 RLOCK 1 or 2)
– Can be used for FAI
– Dry Rating 5 Amps @ 30 Vdc or 30 Vac
– Wet Rating 0.75 Amps @ 30 Vdc
– Form C
Secondary Relay (permanently soldered)
–8 per ACM
– Can be Wet or Dry (Wet powered by either RLOCK 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.
There are eight basic sections of the ACM visible in the silk screen.
Figure 6 on page 21 indicates all of the components of sections 1 and 8. This
pair is typical of the other 3 pairs. It also shows the Power In ports and the FAI
controls.
