The supply that anchors an access control enclosure. Select 12 VDC at 4A or 24 VDC at 3A, wire two 12V batteries behind it, and the doors keep working through a power failure instead of failing to whatever state the hardware defaults to.
Built for the commercial installer
Main and auxiliary outputs let you separate the controller feed from the door hardware feed at the supply rather than downstream. System fault relays give you a dry contact to supervise, so a failed supply reports as a trouble instead of being discovered when someone cannot badge in. Low battery cutoff protects the battery set from the deep discharge that kills sealed lead acid early.
Set the battery voltage to match the DC output voltage. In an Alarm.com deployment feeding a B100 and a door controller, Alarm.com specifies the 24V setting, because dropping the supply to 12V leaves the B100 and the F8 distribution module without the second voltage rail the enclosure is built around. This is the board only, with no enclosure, so specify a can separately or order it as part of the ADC-AC-LP1501-PSE kit.
Key features
- One board covers both voltages, selectable 12V at 4A or 24V at 3A, so stock does not need to be split by job type
- Battery backup built in, taking two 12V batteries at 4Ah or 7 to 9Ah
- System fault relays give the panel a supervised contact, so a dead supply reports instead of hiding
- Low battery cutoff keeps a deep discharge from destroying the battery set
- Separate main and auxiliary outputs to split controller and door hardware at the source
System requirements
Accepts 120 VAC or 230 VAC input and requires a separate enclosure, since this is the board only. Battery set voltage must match the selected DC output voltage. For Alarm.com access control enclosures feeding a B100 and door controller, use the 24V setting.
