Locknetics LP150 – Frequently Asked Questions

1) Should I order the LP150 or the LP250 for my access control doors?
Go by door count and total lock draw. The LP Series covers most single or double door applications, with the LP150 at 1.5 amps and the LP250 at 2.5 amps. The LP250 is also the only one of the two that accepts the RDB4 four output relay distribution board, so if you want the supply to feed and switch several devices separately, order the LP250.
2) What is the difference between the Locknetics LP150 and LP150B?
The B suffix means board only. LP150 and LP250 ship with an enclosure; LP150B and LP250B are the bare power supply boards with no cabinet, meant to drop into an existing enclosure. If you are replacing a failed supply in a cabinet that is already mounted and wired, the board only version is what you want.
3) Will a Locknetics LP board fit in the power supply cabinet I already have on the wall?
The LP boards use an industry common power supply board footprint, which is why Locknetics calls field replacement simple. That is what makes the LP150B and LP250B board only versions a practical swap into an existing enclosure rather than pulling the whole cabinet off the wall. Confirm your cabinet's standoff pattern matches before you cut anything loose.
4) Does the Locknetics LP150 support battery backup, and does it charge the batteries?
Yes, both LP models have a built-in charger for battery backup. You add the batteries; the supply keeps them topped off and carries the locks through a power loss. That is the piece people forget to check when they buy a bare supply and then find the doors unlock the moment the panel drops.
5) Can the Locknetics LP power supply drop mag locks on a fire alarm signal?
Yes. The LP Series has the ability for fire alarm integration, so the supply can release power to the locking devices when the alarm system signals. For a mag lock or fail safe electric strike on an egress door, that fire alarm interface is usually a code requirement in the AHJ's review, so it is worth confirming your installer wires it rather than leaving the terminals open.
6) What matches the 1.5 amp Locknetics LP150 power supply?
The LP150 is the 1.5 amp member of the LP Series, sold with enclosure or as the LP150B board only. Comparable 1.5 amp units include the SDC 631 Series, a 1.5 amp regulated and filtered DC power controller with dual voltage selection, and the Command Access PS210, a UL 6E/CSA linear supply with 1.5A at 24VDC and boost circuitry. The SDC 631 offers dual voltage selection in the same way the LP150 offers field selectable output voltage; the Command Access PS210 is fixed at 24VDC.
7) I need more than 2.5 amps for a bank of maglocks. What should I use instead of the Locknetics LP Series?
The LP Series tops out at 2.5 amps with the LP250, which the manufacturer positions for most single or double door applications. For a larger load, step to the SDC 634 Series, a 4 amp regulated and filtered low voltage supply with dual voltage selection, or the Securitron AQL4 switching supply at 12/24VDC and 4/3 amps. Larger still are the BEST PS161-6 at 120V input, 12/24V output and 6A capacity, the Aiphone AC-PS1250 at 12V DC 5A UL listed, the Securitron AQS1210 at 12 VDC 10 amp, and the Altronix AL1024ULACMCB at 24VDC 10A with 8 PTC outputs.
8) Which power supply do I need for motorized latch retraction exit devices instead of the Locknetics LP Series?
The LP Series is a general Class 2 access control supply for single or double door applications, with the RDB4 four output relay distribution board available on the LP250. Motorized latch retraction draws an inrush that calls for a purpose-built unit: the BEST RPSMLR2 Series is a power supply for motorized latch retraction exit devices. For delayed egress exit devices, the BEST PS161-6 is built for that duty at 120V input and 12/24V output with 6A capacity.
9) Which access control power supplies are UL listed for a facility that requires it?
The Locknetics LP Series is UL294 certified and Class 2, covering both the 1.5 amp LP150 and the 2.5 amp LP250. Among the peers, the Aiphone AC-PS1250 is UL listed at 12V DC 5A, the Command Access PS210 is UL 6E/CSA listed at 1.5A 24VDC, the Altronix AL1024ULACMCB carries UL in its designation, and the ROFU 9102-12D is listed UL. The LP Series also supports fire alarm integration, which matters where the authority having jurisdiction requires locks to release on alarm.
10) How do I power several separate doors or devices from one Locknetics LP250?
Add the RDB4 option board. It is a four output relay distribution board that mounts to the LP250 and splits the supply into four switched outputs, so each opening gets its own controlled feed. It is sold separately and it works with the LP250 only, not the LP150.
11) What do I need to order besides the LP250 to finish an access control power install?
Order the enclosure version unless you already have a cabinet, in which case the LP250B board only is the part. Backup batteries are separate; the charger is built in but the batteries are not included. If you are feeding more than one device and want them switched independently, add the RDB4 four output relay distribution board, which is sold separately and fits the LP250 only.
12) I am powering one electric strike. Is there something smaller than the Locknetics LP150?
The LP150 is a 1.5 amp supply and the smallest in the LP Series. For a single small load, the 1 amp options are the Adams Rite PS-1 regulated power supply at 1 amp, 12/24 volts DC with battery backup, the SDC 620 Series 1 amp regulated and filtered low voltage supply with dual voltage selection, the Command Access PS1 Series 24VDC linear supply with 1 amp output, and the Securitron AQD1 switching supply at 12/24 VDC 1 amp. The Adams Rite PS-1 carries battery backup like the LP Series built-in charger; the Command Access PS1 is 24VDC only rather than dual voltage.
13) I need several independently controlled outputs. How does that compare to the Locknetics LP250 with the RDB4?
On the LP250 the output count comes from the RDB4 option board, a four output relay distribution board sold separately and offered on the LP250 only. Units that carry multiple outputs in the base product include the RCI DKPS-2A with 8 outputs at 12/24VDC and 2A, and the Altronix AL1024ULACMCB power supply and access power controller with 8 PTC outputs at 24VDC 10A from a 115VAC 60Hz 4.2A input. Note the RDB4 is not offered for the LP150.
14) What is the difference between the Locknetics LP250B board and buying a whole new power supply?
The LP250B is the 2.5 amp board on its own, and Locknetics states field replacement is simple because the LP Series uses an industry common power supply board footprint - so a failed board in an existing can is swapped without replacing the enclosure. Peers in the comparable set are sold as complete units: the Von Duprin PS902 is a base power supply at 2A 12/24 VDC field selectable, and the SDC 632 Series is a 2 amp regulated and filtered low voltage supply with dual voltage selection. Choose the board when the enclosure and wiring stay, the complete unit for a new install.
15) I need door logic and sequencing, not just power. What takes the place of a Locknetics LP250?
The LP250 supplies power and, with the RDB4 option board, distributes it across four relay outputs; the LP Series also supports fire alarm integration. Where the opening needs decision logic rather than distribution, the Detex 10-800 Series is a universal logic controller with a 120VAC/24VDC power supply and battery backup built in, and the BEST ELR150 Series is a power supply control module for electronic access control. Both bundle control functions with the power rather than leaving control to a separate panel.
16) Is there an alternative to the Locknetics LP Series for an opening with no building power run to it?
The LP Series is a hardwired Class 2 supply with a built-in charger for battery backup, which assumes line power at the door. Where no branch circuit is available, the Securitron BPSS is a boxed solar power supply. For bench work and testing rather than a permanent install, the Command Access CAT Field Tester is a portable 12-24VDC supply compatible with DeWalt, Makita and Milwaukee batteries.
17) Which power supplies besides the Locknetics LP Series let me pick 12 or 24 volts in the field?
The LP150 and LP250 both have field selectable output voltage, so one part number covers 12V and 24V devices across a facility. Peers with the same flexibility are the Von Duprin PS902 at 2A 12/24 VDC field selectable, the SDC 620, 631, 632 and 634 Series, all listed with dual voltage selection at 1, 1.5, 2 and 4 amps respectively, the Securitron AQD1 at 12/24 VDC 1 amp, and the Adams Rite PS-1 at 1 amp 12/24 volts DC. Fixed-output units in the same class include the Command Access PS1 and PS210, both 24VDC, and the Securitron AQS1210 at 12 VDC.
18) Is this power supply for commercial buildings or residential use?
The Locknetics LP Series is a commercial product. It is a UL294 Class 2 access control supply for electrified door hardware, sized for single and double door openings in commercial and institutional buildings, not for residential smart locks.
19) Switching or linear - how does the Locknetics LP250 compare to the alternatives?
The Command Access PS204/204B is a linear power supply with 2A at 24VDC and battery backup, and the Command Access PS1 Series and PS210 are linear as well. The Securitron AQD1, AQL4 and AQS1210 are switching supplies at 12/24 VDC 1 amp, 12/24VDC 4/3 amp and 12 VDC 10 amp. The LP250 is a 2.5 amp Class 2 unit with field selectable output voltage and a built-in charger for battery backup, so it sits alongside the 2 amp linear PS204/204B and the Von Duprin PS902 in capacity while offering an enclosure or board-only build.
