DocumentDocumentAL175ULB Access Control Power Supply/Charger Overview: AL175ULB is a power-limited power supply/charger that converts a 24VAC input into two (2) individual PTC protected auto-resettable 12VDC or 24VDC outputs (see specifications). They are intended for use in applications requiring UL Listing for Access Control (UL 294) and applications requiring an interface with Fire Alarm Control Panels. Specifications: Agency Listings: Battery Backup: · UL Recognized component for · Built-in charger for sealed lead acid or Access Control Systems (UL 294). gel type batteries. Input: · Input 24VAC, 40VA. Class 2 transformer. · Fire Alarm Panel or Access Control trigger input. · Automatic switch over to stand-by battery when AC fails. · Maximum charge current 0.4A. Output: · 12VDC or 24VDC selectable outputs. · 12VDC @ 1.75A or 24VDC @ 0.9A supply current. · Two (2) Class 2 Rated power-limited outputs. Supervision: · AC fail supervision (form "C" contacts). · Supervised Fire Alarm Disconnect (Latching w/reset or Non-Latching). - Fail-Safe/Fail-Secure lock output (switched). Visual Indicators: - Auxiliary power output (unswitched). · AC input and DC output LED indicators. · PTC protected outputs, rated @ 2.5A. · Filtered and electronically regulated output. · Short circuit and thermal overload protection. Board Dimensions (W x L x H approximate): 3.1" x 5.8" x 1.5" (78.7mm x 147.3mm x 38.1mm). Power Supply Output Specifications: Output VDC Switch Position Max. Stand-by Load DC Max.

See Terminal Identification Chart on page 3 for a description of each terminal function. 1. Mount AL175ULB in the desired location/enclosure (mounting hardware included). 2. Connect 28VAC, 56VA transformer to the terminals marked [AC AC]. 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 0.25" spacing must be provided. 3. Set the AL175ULB to the desired DC output voltage by setting switch SW1 to the appropriate position (see Power Supply Output Specification Chart, pg. 1). 4. Measure output voltage before connecting devices. This helps avoiding potential damage. 5. Connect battery to the terminals marked [+ BAT -] on the unit (battery leads included). Use two (2) 12VDC batteries connected 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 is desired, they must be lead acid or gel type. - 1 - AL175ULB Installation Guide 6. Connect appropriate signaling notification devices to AC Fail supervisory relay outputs. Note: To meet UL requirements, AC Supervisory outputs must be connected to the zone of Alarm Control Panel or to visual AC trouble indicator. 7.

Terminal Identification: Terminal Legend Function/Description AC Low voltage AC input. TRG1 & 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 AL175ULB 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 AL175ULBs with fire alarm tie-in (Fig. 4, pg. 3 and Fig. 5, pg. 4). AUX+ COM -FACP +BAT -AC Fail N.C., C, N.O. Continuous positive (+) DC power output voltage. It is not affected by TRG1, TRG2 operation. Common negative (-) output (ground). Spare wiring terminal used for fire alarm tie-in application (Fig. 3, pg. 3). Stand-by battery connections. Used to notify loss of AC e.g connect audible device or alarm panel relay normally energized when AC power is present. Contact rating 1A @ 28VDC. - 2 - AL175ULB Installation Guide 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 (Power Supply Output Specifications Chart). 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 discharge is 400mA. Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.
