2.7.1 CAC-5X Class A Converter Module
Installation
The CAC-5X Module can be used to convert five Style B (Class B) Initiating Device Circuits to Style D (Class A) and the two Style Y
(Class B) Notification Appliance Circuits to Style Z (Class A). The module plugs into connector J2 which is located at the top left of the
GF505 and GF510 main circuit board and J7 which is located at the top center of the GF510.
Note that two CAC-5X modules are
required to convert all NACs and IDCs on the GF510 to Class A circuits.
To install the CAC-5X in the GF505 or GF510, remove the two main circuit board mounting screws referenced in the following illustra-
tion and replace with the two supplied male/female standoffs in the locations indicated in the following figure. Carefully align the con-
nector on the CAC-5X with J2 on the FACP main circuit board and press the module securely into place. Make certain the pins are
properly aligned to prevent bending or breaking of any connector pins. Secure the CAC-5X to the standoffs with the screws that were
just removed.
To install the second CAC-5X on J7 of the GF510, remove the main circuit board mounting screw referenced in the following illustration
and replace with the supplied male/female standoff.
Next, insert a male/female standoff in circuit board of the FACP as shown below
and secure with a hex nut from the hardware kit. Use a pair of needle-nose pliers to hold the hex nut while securing. Carefully align the
connector on the CAC-5X with J7 and press the module securely into place. Make certain the pins are properly aligned to prevent
bending or breaking of any connector pins. Secure the top right corners of the CAC-5X to the standoffs with the screw that removed in
step 1 and another from the hardware kit.
Wiring NACs and IDCs for Class A
Wire the Style Z (Class A) Notification Appliance Circuits using TB5 of the GF505/GF510 and TB2 of the CAC-5X module. Wire the
Style D (Class A) Initiating Device Circuits using TB4 of the GF505/GF510 and TB1 of the CAC-5X. Note that the wiring will be iden-
tical when using TB7 NAC and TB6 IDC of the GF510. Make certain to observe polarity when connecting the devices to the circuits.
The B+ and A+ terminals must comprise the feed and return for the positive side of a device and the B- and A- terminals must comprise
the feed and return for the negative side of a device. To configure any of the zones for Class B when the CAC-5X is installed, simply
wire to the B+ and B- input on the FACP terminal(s) and install the End-of-Line Resistor after the last device on the circuit. Do not wire
!
WARNING: RISK OF ELECTRICAL SHOCK
REMOVE ALL POWER (AC AND DC) BEFORE INSTALLING OR REMOVING MODULES OR WIRING.
