Activate on FAI
SW2, SW4, SW22, SW19, SW18, SW6, SW26, SW23
The Primary relays (large, mounted in sockets) can be configured to Activate when the FAI
signal goes true.
FAI on this ACM - SW31
There are identical FAI controls on all ACMs. Set this switch to ON on the ACM that is sensing
the FAI and KEY signals.
Using the FAI Pull-Up Resistor
There must be a pull-up resistor in the circuit for the FAI to operate (regardless of whether
or not the FAI switch is supervised). If you are using one ACM with an individual FAI
switch, the pull-up resistor switch must be in the ON (enabled) position.
If the FAI switch is to be wired to multiple ACM boards, it should be wired in parallel to
FAI connectors on each board. If the FAI switch is supervised, or unsupervised, the pull-
up resistor should be enabled (ON) on only one ACM board, and disabled (OFF) on the
other ACM boards
Enable FAI Latch - SW30
If FAI Latch is true, all relays that have Activate on FAI true, will latch and remain latched
until the KEY signal resets them
Ports and Connectors
J1 USB connection to GCM
USB cable connection to the GCM.
Tamper - J22
The NC Tamper is connected to the GCM. Do not connect it here. Place a jumper across the
two pins and be sure the ACM Tamper is not configured in the C•CURE software.
Reader Power - J4
This is the primary power input to the ACM. (12 Vdc @ 0.5 to 12.5 Amps maximum)
The input power is also the voltage supplied on the reader power lines.
When connecting power to J2, J3, or J4, observe polarity as indicated in Figure 6-5 on page 6-8.
The plus (+) sign is located on the bottom pin.
NOTE
Shielded cable must be used for AC fail and Low Battery Input connections.
