AL1024NK1 Installation Guide
- 3 -
Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, The Canadian
Electrical Code, Part 1 and with all local codes and authorities having jurisdiction. The product must be located
indoors within the protected premises.
1. Mount unit in 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 the 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. 9)
. Secure enclosure to earth ground.
2. Connect unswitched AC power (115VAC, 60Hz) to terminals marked [L, N]
(Fig. 1a, pg. 4)
. Use 14 AWG
or larger for all power connections. Secure green wire lead to earth ground.
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.
3. Measure output voltage before connecting devices. This helps avoiding potential damage.
4. Select VR6’s output voltage (5VDC or 12VDC) using switch [S1]
(Fig. 2a, pg. 5)
.
5. Connect devices to be powered:
a. For 24VDC connect device(s) to terminals marked [+ DC –] on AL1024ULXB2 (power supply board)
(
Fig. 1h, pg. 4, Fig. 2, pg. 5
).
b. For 5VDC or 12VDC connect device(s) to terminals marked [+ OUT –] on VR6
(Fig. 2b, pg. 5)
Carefully observe correct polarity.
6. For Access Control applications batteries are optional. When batteries are not used, a loss of AC will result
in the loss of the output voltage. When the use of stand-by batteries is desired, they must be lead acid or gel
type. Connect battery to terminals marked [– BAT +]
(Fig. 1g, pg. 5)
. Use two (2) 12VDC batteries connected
in series for 24VDC operation (battery leads included) Use batteries - Casil CL1270 (12V/7AH),
CL12120 (12V/12AH), CL12400 (12V/40AH), CL12650 (12V/65AH) batteries or UL recognized BAZR2
batteries of an appropriate rating.
7. Connect appropriate signaling notification devices to AC FAIL & BAT FAIL
(Fig. 1b, pg. 4)
supervisory
relay outputs.
8. To delay reporting for up to 6 hrs., cut “AC Delay” jumper and reset power to unit
(Fig. 1f, pg. 4)
.
9. For Access Control Applications: mount UL Listed tamper switch (Altronix model TS112 or equivalent) at
the top of the enclosure. Slide tamper switch bracket onto the edge or the enclosure approx. 2” from the
right side
(Fig. 2, pg. 5)
. Connect tamper switch wiring to the Access Control Panel input or the appropriate
UL Listed reporting device.
Wiring:
Use 18 AWG or larger for all low voltage power connections.
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 AL1024NK1: 24VDC nominal rated @ 10A max.
Battery Test:
Under normal load conditions check that the battery is fully charged, check specified voltage
(24VDC @ 26.4) both at 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 3.6A.
Note:
Expected battery life is 5 years, however it is recommended changing batteries in 4 years or less if needed.
