Installation Instructions
The 10-175UL should be installed in accordance with article 760 of The National Electrical
Code or NFPA 72 as well as all applicable Local Codes.
See Terminal Identification Chart on page 4 for a description of each terminal function.
1.
Mount the 10-175UL in desired location.
2.
Connect AC power (115VAC 60Hz) to the black and white flying leads of the trans-
former. Secure green wire lead to earth ground. Use 18 AWG or larger for all power
connections (Battery, DC output). Use 22 AWG to 18 AWG for power limited circuits
(trigger inputs, dry outputs).
Keep power limited wiring separate from non-power limited wiring (115VAC/ 60Hz
Input, Battery Wires). Minimum .25” (6.4mm) spacing must be provided.
3.
Set the 10-175UL to the desired DC output voltage by setting switch SW1 to the appro-
priate position (power supply output specification table).
Note: It is good operating practice to measure and verify output voltage before con-
necting devices to ensure proper operation of equipment.
4.
Connect battery to terminals marked [+ BAT -] (battery leads included). Use two (2)
12VDC batteriesconnected in series for 24VDC operation.
Note: 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 are desired, they must be lead acid or gel type.
5.
Connect appropriate signaling notification devices to AC Fail supervisory relay outputs
marked [N.C., N.O., C].
Note: To meet UL requirements, AC Supervisory outputs must be connected to the
zone of Alarm Control Panel or to visual AC trouble indicator.
6. For Access Control Device & Fire Alarm Interface connections refer to desired
Application Diagrams (pg. 6-8) and Terminal Identification Chart
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 (see power supply output specifica-
tions chart).
Battery Test
:
Under normal load conditions check that the battery is fully charged,
check specified voltage both at battery terminal and at the board ter-
minals marked [- BAT +] to insure there is no break in the battery
connection wires.
Note: Maximum charging current under discharges is 0.40 amps.
Note: Expected battery life is 5 years, however it is recommended changing batteries in
4 years or less if needed.
