FACP Dry form “C” output (Fig. 2a, pg. 8):
FACP form “C” contacts can be use to trigger reporting or signaling devices. These contact switch
upon a fire alarm input trigger to the ACM8CB boards.
10.
Stand-by Battery Connections (Figs. 3-7, pgs. 9-13):
For Access Control applications batteries are optional. If batteries are not used a loss of AC will result in the loss of
output voltage. Batteries must be lead acid or gel type. Connect one (1) 12VDC battery to the terminals marked
[+ BAT -] for 12VDC operation (Fig. 3a, pg. 9). Use two (2) 12VDC batteries wired in series for 24VDC operation.
11.
Battery and AC Supervision outputs (Figs. 3-4, pgs. 9-10):
It is required to connect supervisory trouble reporting devices to outputs marked [AC Fail, BAT FAIL] supervisory
relay outputs marked [NC, C, NO] to appropriate visual notification devices. Use 22 AWG to 18 AWG for
AC Fail & Low/No Battery reporting.
12.
Installation of tamper switch (Not Included) (Figs. 3b-4a, pgs. 9-10):
Mount UL Listed tamper switch (Sentrol model 3012 or equivalent) at the top of the enclosure. Slide the tamper
switch bracket onto the edge of the enclosure approximately 2” from the right side (Figs. 3b and 4a, pgs. 9-10).
Connect tamper switch wiring to the Access Control Panel input or the appropriate UL Listed reporting device.
To activate alarm signal open the door of the enclosure.
Maintenance:
Unit should be tested at least once a year for the proper operation as follows:
FACP Supervision: To insure 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: Remove 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. 10, pg. 14) or Normally Closed (Fig. 12, pg. 14) 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
(Power Supply Board Stand-by Battery Specifications, pg. 7).
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: AL600ULXB and AL1012ULXB Power Supply Board maximum charge current is 0.7 amp.
AL1024ULXB2
Power Supply Board maximum charge current is 3.6 amp.
Expected battery life is 5 years; however, it is recommended to change batteries within 4 years or less if necessary.
