Enclosures:
FN-1024ULX-R (Red Enclosure)
FN-1024ULX-C (Charcoal Grey Enclosure)
Enclosure Dimensions (H x W x D) :
15.5” x 12” x 4.5” (393.7mm x 304.8mm x 114.3mm)
Installation Instructions:
The unit should be installed in accordance with article 760 of The National Electrical Code as well as NFPA 72 and all
applicable Local Codes.
1. Mount unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes in the
enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place the enclosure’s
upper keyholes over the two upper screws; level and secure. Mark the position of the lower two holes. Remove the
enclosure. Drill the lower holes and install two fasteners. Place the enclosure’s upper keyholes over the two upper
screws. Install the two lower screws and make sure to tighten all screws (Enclosure Dimensions, pg. 6).
2. Connect AC power (115VAC / 60 Hz) to the terminals marked [L, N] (Fig. 1, pg. 3). Use 14 AWG or larger for all
power connections (Battery, DC output, AC input). Use 22 AWG to 18 AWG for power-limited circuits (AC Fail/
Low Battery reporting).
Keep power-limited wiring separate from non power-limited wiring (115VAC / 60Hz Input, Battery Wires).
Minimum 0.25” spacing must be provided.
CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or servicing equipment.
There are no user serviceable parts inside. Refer installation and servicing to qualified service personnel.
For Fire Alarm applications the outputs are “Special Applications” only.
3. Measure output voltage before connecting device. This helps avoiding potential damage.
When servicing the unit, AC mains should be removed.
4. Connect devices to be powered to terminals marked [+ DC -], carefully observing correct polarity (Fig. 1, pg. 3).
5. For Access Control applications batteries are optional. When batteries are not used, a loss of AC will result in
the loss of output voltage. When the use of stand-by batteries is desired, they must be lead acid or gel type.
6. Connect appropriate signaling notification devices to the terminals marked [AC FAIL & BAT FAIL] (Fig. 1, pg. 3)
supervisory relay outputs.
Note: When used in fire alarm, burglar alarm or access control applications, “AC Fail” relay must be used to
provide a visual indication of AC power on.
7. Please ensure that the cover is secured with the provided Key Lock.

Fig. 1 CAUTION: De-energize unit prior to servicing. For continued protection
against risk of electric shock and fire hazard replace fuses with the same type
and rating. Do not expose to rain or moisture.

L, N Connect 115VAC 60Hz to these terminals: L to hot, N to neutral. Do not use the [G] terminal.
+ DC --- 8 amp supply current in non-alarm condition with 10 amp supply current during alarm for Fire
Alarm Applications. 10 amp supply current for Access Control Applications.
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 1 amp @ 28VDC. AC or brownout fail is
reported within 1 minute of event. To delay reporting for up to 6 hrs., cut “AC delay” jumper and
reset power to unit.
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 1 amp @ 28VDC. A removed battery is reported within 5 minutes.
Battery reconnection is reported within 1 minute.
Low battery threshold: 24VDC output threshold set @ approximately 21VDC.

6.5 hrs. for 24VDC/65AH battery.
See battery size calculation worksheet for other batteries (Page 5).
Use 14 AWG or larger for all power connections.
Wiring:
Note: Take care to keep power-limited circuits separate from non power-limited wiring (115VAC, Battery).
Maintenance:
Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test: Under normal load conditions the DC output voltage should be checked for proper voltage level.
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage both at the
battery terminal and at the board terminals marked [– BAT + ] to ensure that there is no break in the battery connection wires.
Note: Maximum charging current under discharges is 3.6 amp.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.

Note: FN-1024ULX power supply is designed to work with batteries up to 65AH. Please note, line [I] must not
exceeds 36AH. You have to reduce either stand-by current consumption or stand-by time in order to comply
with requirement.
To determine actual battery size please round line [J] to the nearest larger standard battery size
(e.g. 3.5 AH = 4.0 AH).
