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 transformer. 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 appropriate position (power supply output specification table). Note: It is good operating practice to measure and verify output voltage before connecting 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 standby 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 specifications 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 terminals 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. 3 Terminal / Switch Identifcation: Terminal Legend Function/Description TRGI & TRG2 These input terminals are designed to connect to the normally closed outputs of an access control or fire alarm relay. These terminals control [LOCK+], and [STRIKE+], as well as 10-175UL output relay contacts [N.C., N.O., C] LOCK+ This terminal provides DC output voltage when [TRG1] and [TRG2] are shorted together and are typically used to power Mag Locks. STRIKE+ This terminal provides DC output voltage when [TRG1] and [TRG2] are unshorted and are typically used to power Electric Strikes. N.C., N.O., C Isolated dry Form “C” contacts. Shorting [TRG1] and [TRG2] together causes these contacts to switch. They are typically used for controlling multiple 10-175ULs with fire alarm tie-in (Fig. 4 and Fig. 5, pg. 7-8). AUX+ Continuous positive (+) DC power output voltage. It is not affected by TRG1, TRG2 operation. COM – Common negative (-) output (ground). FACP Spare wiring terminal used for fire alarm tie-in application (Fig. 1, pg. 6). BAT+, BAT – Stand-by battery connections. SW2 Momentary reset button (on front door) is used as a manual power supply reset after fire alarm system is restored.
