AL201UL Access Control Power Supply/Charger
v. 021201
Re
Overview:
AL201UL is a power limited power supply/charger that converts a 24VAC / 60Hz plug in Transformer input, into 12VDC output, (refer to specifications). The AL201UL is UL Listed for Burglar Alarm Installation (UL603), and for Access Control (UL294). It must be installed in accordance with National and Local Electrical Codes and Regulations.
Specifications:
• UL Listed Burglar Alarm and Access Control (UL603, UL294).
• Input 24VAC, 40VA from UL Listed Class 2 direct plug-in transformer.
• 1.75 amp continuous supply current @ 12VDC.
• Filtered and electronically regulated output.
• Maximum charge current: 400mA.
• Automatic switch over to stand-by battery when AC fails (zero voltage drop).
• AC fail supervision (form "C" 1 amp @ 28VDC).
• Low battery supervision (form "C" 1 amp @ 28VDC).
• AC input and DC output LED indicators.
• Short circuit and thermal overload protection.
• Includes power supply, enclosure and battery leads.
Enclosure Dimensions: 8”H x 7.25”W x 3.5”D
Power Supply Output Specifications:
Output VDC Max. Stand-by Load DC Max. Alarm Load DC Battery (optional)
12VDC 1.75 amp 1.75 amp 12VDC / 7AH
Stand-by Specifications:
Output 4 hr. of Stand-by &
5 Minutes of Alarm
12VDC / 7 AH Battery Stand-by = 1.25 amp
Installation Instructions:
The AL201UL should be installed in accordance with The National Electrical Code as well as all applicable Local Codes.
Refer to Terminal Identification Chart on page 2 for a description of each terminal function.
1. Mount the AL201UL in desired location.
2. Connect 24VAC, 40VA UL Listed Class 2 direct plug-in transformer to terminals “XFMR INPUT”.
Use 18 AWG or larger for all power connections (Battery). Use 22 AWG to 18 AWG for power limited circuits (DC output, AC FAIL and LOW BAT supervisory relays).
K
eep po Minimum .25” spacing must be provided. Note:

3.
4. Connect appropriate signaling notification devices to AC Fail and Low Bat 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. 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.

Terminal Function/Description Legend
XFMR INPUT Low voltage AC input.
+ DC OUT --- Continuous positive (+) DC power output voltage. Common negative (-) output (ground).
+ BAT --- Stand-by battery connections.
AC FAIL Used to notify loss of AC e.g connect audible device or alarm panel. Relay is normally N.O., C, N.C. energized when AC power is present. Contact rating 1 amp @ 28VDC.
LOW BAT Used to notify low battery condition e.g connect audible device or alarm panel. Relay is N.O., C, N.C. normally energized. Contact rating 1 amp @ 28VDC.
