Maximal3FV / Maximal5FV / Maximal7FV Access Power Controllers (Fused)
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 ACM8s 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 configuredfor Normally Open (Fig. 7, pg. 11) or Normally Closed (Fig. 9, pg. 11) 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 MaximalFV series Configuration Chart, pg. 3).
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 1.54A.
Expected battery life is 5 years; however, it is recommended to change batteries within 4 years or less if necessary.

FACP interface latching or non-latching (Fig. 3, pg. 9).
+ AUX –
Auxiliary output rated @ 1A (unswitched) (Fig. 3, pg. 9).
AC FAIL
NC, C, NO
Indicates loss of AC power, e.g. connect to audible device or alarm panel.
Relay normally energized when AC power is present.
Contact rating 1A @ 30VDC (Fig. 3, pg. 9).
BAT FAIL
NC, C, NO
Indicates low battery condition, e.g. connect to alarm panel. Relay normally energized
when DC power is present. Contact rating 1A @ 30VDC.
A removed battery is reported within 5 minutes.
Battery reconnection is reported within 1 minute (Fig. 3, pg. 9).
+ BAT –
Stand-by battery connections.
Maximum charge current 1.54A (Fig. 3, pg. 9).
