15. Multiple power supply inputs (Fig. 2, pg. 7) (Not evaluated by UL):
When using an additional Listed external power supply, jumpers J1 and J2 located on corresponding ACM8CB board must be
cut (Fig. 2c, pg. 7 and Fig. 5, pg. 10). Connect external Listed power-limited access control power supply to the terminals
marked [- Control +] (These terminals are paralleled to the - Power + terminals). When using DC power supplies, polarity must
be observed. When using AC power supplies, polarity needs not be observed (Fig. 2d, pg. 7). All field wiring connections must
be made employing suitable gauge CM or FPL jacketed wire (or equivalent substitute) (Fig. 4a, pg. 9).
Maintenance:
Unit should be tested at least once a year for the proper operation as follows:
FACP Supervision: To ensure proper connection and operation of the Fire Alarm disconnect hookup please follow
the appropriate procedure below:
Normally Open Input: Placing a short between terminals marked [T] and [+ INP] will trigger the Fire Alarm Disconnect.
Remove the short to reset.
Normally Closed Input: Removing the wire from terminal marked [INP -- ] will trigger the Fire Alarm Disconnect.
Replace the wire to terminal marked [INP -- ] to reset.
FACP Signal Circuit Input: It is necessary to trigger the Fire Alarm System.
In all of the above scenarios the green TRG LED of the ACM8CBs will illuminate. All outputs selected for Fire Alarm
Disconnect will activate releasing locking devices.
Note: All outputs [OUT 1 - OUT 8] must be in a normal (de-energized) condition prior to testing. When the unit is configured
for Normally Open (Fig. 8, pg. 10) or Normally Closed (Fig. 9, pg. 10) latching operation it is necessary to reset the Fire Alarm
Disconnect by activating the Normally Closed reset switch.
Output Voltage Test: Under normal load conditions the DC output voltage should be checked for proper voltage level
(refer to MaximalFD series Configuration Chart, pg. 2).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage at the battery terminals
and at the board terminals marked [+ BAT -] to ensure that there is no break in the battery connection wires.
Note: Maximum charge current is 1.54 amp.
Expected battery life is 5 years; however, it is recommended to change batteries within 4 years or less if necessary.
