Securitron AQD2-4C1R1 – Frequently Asked Questions

1) How many doors can a 2 amp Securitron AQD2 supply actually power?
Budget by current draw, not door count. The AQD2 gives 2 amps total at 12 or 24 VDC, and the distribution board splits that across either 4 or 8 independently controlled power limited outputs depending on which configuration you order. Each output is fused at 1 amp or 2 amps. Add up the holding current of every strike, mag lock or electrified device on the board; if the total exceeds 2 amps you need a larger supply, not more outputs.
2) Does the Securitron AQD2 drop mag locks on a fire alarm signal?
Yes, it has a fire alarm relay. You order it either as a single relay fire trigger that kills every output at once, or as individually triggered relayed outputs so only the openings on the fire plan release. Relay counts offered are 0, 1, 2 or 8, so a board with 8 outputs and 8 relays gives you per-door release. Order 0 relays only where the locks are fail secure and no alarm release is required.
3) Can the Securitron AQD2 keep doors powered during a power outage?
It has an integrated battery charging circuit and supports up to two sealed gel, AGM or wet lead acid batteries for standby. The charging circuit is built to prevent overvoltage reaching the locking devices, which matters on mag locks and electric strikes that will cook on an unregulated charge. Batteries are a separate purchase, sized to the runtime your authority having jurisdiction requires.
4) My load is over 2 amps. What should I order instead of the Securitron AQD2?
Step up rather than paralleling supplies. The Altronix AL1024ULACMCB is 24VDC at 10A with 8 PTC outputs and a built in access power controller, off 115VAC 60Hz at 4.2A. The BEST PS161-6 is 120V in, 12/24V out at 6A capacity. The SDC 634 Series is a 4 amp regulated and filtered dual voltage supply. If the load is a bank of motorized latch retraction exit devices, those have an inrush problem a general purpose supply will not handle, and the BEST RPSMLR2 is built for them.
5) What is the closest equivalent to the Securitron AQD2 power supply from another brand?
The Securitron AQD2 is a 2 amp, 12 or 24 VDC field selectable switching supply for access control. The closest cross-brand match on those numbers is the Von Duprin PS902 base power supply, which is also rated 2A at 12/24 VDC field selectable for access control. The RCI DKPS-2A is another 12/24VDC 2A supply and it comes with 8 outputs, which lines up with the AQD2 built out with a distribution board carrying 8 outputs.
6) The AQD2 does not have enough current for my door count. What steps up from it?
The AQD2 delivers 2 amps at either 12 or 24 VDC. When the load list runs past that, the SDC 634 Series is a 4 amp regulated and filtered supply with dual voltage selection, and the BEST PS161-6 runs 120V input to 12/24V output at 6A capacity. The Altronix AL1024ULACMCB is a larger step again at 24VDC 10A with 8 PTC outputs on a 115VAC 60Hz input, so it covers the distribution role as well as the current.
7) What looks like a substitute for the AQD2 but will not do the job?
Two items sit near it in a search and do something else. The ROFU 10305-LA/10306-LA is a power transfer hinge rated 1.5A at 42V, tamper resistant, in a white plastic finish, which carries power through the door rather than generating it. The Command Access CAT Field Tester is a portable 12-24VDC supply that runs off DeWalt, Makita and Milwaukee batteries for bench and field testing, not a permanent enclosure feed. The AQD2 is the fixed 115 VAC input supply with battery charging behind the openings.
8) My exit devices use motorized latch retraction. Will the AQD2 cover them?
Latch retraction devices have their own inrush behavior and are matched to a dedicated supply. The BEST RPSMLR2 Series is a power supply built for motorized latch retraction exit devices, and the BEST PS161-6 is specified for delayed egress exit devices at 120V input and 12/24V output with 6A capacity. The AQD2 is the general 2 amp 12/24 VDC access control supply with a distribution board for independently controlled power limited outputs.
9) Glass fuses or PTC on an access control power supply, which should I order?
On the AQD2 distribution board both are offered on every output count. Glass fuses open on a fault and have to be physically replaced, which means a truck roll but also an obvious visual indication of which circuit failed. PTC polyswitches are self resetting: clear the short and the output restores itself, no spare fuses on the van. For a building where you are not on site daily, PTC saves the trip. For a supply inside a secured IT room a tech visits anyway, glass is fine.
10) Will a Securitron AQD2 hold up on a building with dirty power or brownouts?
It tolerates brownout or overvoltage input within plus or minus 15 percent of nominal, running off 115 VAC input. It is a switching supply rather than a linear one, so it runs at up to 82 percent efficiency with less heat in the can, and it has thermal shutdown protection with automatic restart if it does overheat. Ripple runs as low as 240 mV peak to peak, which keeps electronics on the door happy.
11) What is a comparable 2 amp 12/24 VDC access control power supply to the Securitron AQD2?
Closest like for like is the Von Duprin PS902 base power supply, also 2A and 12/24 VDC field selectable for access control, listed Grade 1. The RCI DKPS-2A is the nearest match if you specifically want 8 outputs off a 2A 12/24 VDC supply. The SDC 632 Series is a 2 amp regulated and filtered dual voltage supply, and the Command Access PS204/204B gives 2A at 24VDC with battery backup if you only ever need 24 volts.
12) I only have one electric strike to power. Is the Securitron AQD2 overkill?
For a single opening, yes. The AQD2 earns its keep when you need a distribution board splitting power across 4 or 8 supervised, independently controlled outputs with fire release. One door does not need that. The Adams Rite PS-1 is a 1 amp 12/24 VDC regulated supply with battery backup, the SDC 620 Series is a 1 amp dual voltage unit, and the Command Access PS1 Series is 24VDC at 1 amp. For a 12V strike on a plug in, the ROFU 9126T is 12 VDC at 1.5A with a time delay built in.
13) Is the SDC 632 the same thing as a Securitron AQD2?
They share the headline rating but not the design. The SDC 632 Series is a 2 amp regulated and filtered low voltage supply with dual voltage selection, and the AQD2 is a 2 amp 12/24 VDC switching supply with an integrated battery charger, thermal shutdown with auto restart, and a distribution board of 4 or 8 independently controlled power limited outputs. The 632 is a supply; the AQD2 as configured is a supply plus the output distribution behind it.
14) I need fire alarm drop on my locks. Which of these supplies handles that the way the AQD2 does?
The AQD2 carries a fire alarm relay and can be ordered with a single relay fire trigger or with individually triggered relayed outputs, in 1, 2, or 8 relay counts. Among comparable units, the Detex 10-800 Series is a universal logic controller with a 120VAC/24VDC power supply and battery backup, so the sequencing lives in the controller rather than on a distribution board, and the BEST ELR150 Series is a power supply control module for electronic access control.
15) Can I use a Command Access PS204 in place of the AQD2?
Only if the opening is 24 volt. The Command Access PS204/204B is a linear supply rated 2A at 24VDC with battery backup, so the current matches the AQD2 but the voltage does not travel: the AQD2 is field selectable for 12 or 24 VDC. The Command Access PS210 is a UL 6E/CSA linear supply at 1.5A 24VDC with boost circuitry, again 24 volt only and below 2 amps.
16) For a single door retrofit with no enclosure space, what can I use instead of the AQD2?
The AQD2 is a 115 VAC input unit sized for an enclosure with room for up to two sealed gel, AGM or wet lead acid batteries. Where there is no such space, the ROFU 9126T is a plug in mini power supply at 12 VDC and 1.5A with a time delay built in. The ROFU 9102-12D UL/9102-24D takes 10/120VAC 60Hz input and comes in fixed 12 volt and 24 volt versions, so you pick the voltage at order rather than setting it in the field.
17) I am powering an intercom and entry kit, not maglocks. Is the AQD2 the right supply?
The Aiphone AC-PS1250 is a 12V DC 5A UL listed supply made for Aiphone AC Series access control kits, so it is matched to that equipment. The Securitron AQD2 is a dual voltage 12 or 24 VDC UL listed supervised unit at 2 amps with an integrated battery charger and up to 16 independently controlled power limited outputs across the AQ line, aimed at locking hardware on multiple openings.
18) Can I install a Securitron AQD2 power supply in an unheated parking garage or vestibule?
Operating range is -4 to 122 degrees F (-20 to 50 degrees C), which covers an unconditioned garage or a mechanical closet in most of the country. Sustained sub-zero exteriors in the far north fall outside it.
19) Is the Securitron AQD2 suitable for a commercial building, or is it a residential unit?
It is a commercial access control supply. Supervised, UL listed, 115 VAC input, with a distribution board and fire alarm relay, which is the configuration specified on commercial and institutional openings, not on a house.
