Detex 90800 – Frequently Asked Questions

1) Will the Detex 90-800 power supply run a fail-safe electric lock that has to release on a fire alarm?
That is what the 90-800 is built around. It has a dedicated fire alarm input, so when the alarm panel signals, the supply drops power and fail-safe locks release. Output is 24VDC at 1.0A continuous from a 120VAC input, so size the lock load against that 1 amp before you commit the run.
2) Is 1 amp enough for a Detex 90-800 to power my access control devices?
One amp at 24VDC is a single-opening budget. It comfortably covers one electric strike, a maglock, or a small reader-and-lock combination. Multiple maglocks, motorized latch retraction devices, or a whole bank of doors will exceed it. For heavier draw, the SDC 632 gives 2 amps and the SDC 634 gives 4 amps, and the Altronix AL1024ULACMCB puts out 24VDC at 10A across 8 PTC outputs.
3) I need battery backup on the door power supply - what should I use instead of the Detex 90-800?
The Detex 90-800 is a 120VAC to 24VDC 1.0A supply with fire alarm input; battery backup is not part of its feature set. Two peers carry it: the Adams Rite PS-1 is a regulated 1 amp 12/24 volt DC supply with battery backup, matching the 1A output, and the Command Access PS204/204B is a linear supply with 2A at 24VDC and battery backup if you want more headroom on the same 24V bus.
4) What power supply do I use for a delayed egress or motorized latch retraction exit device instead of the Detex 90-800?
Those devices draw an inrush the Detex 90-800's 1.0A continuous 24VDC output is not sized for. The BEST PS161-6 is built for delayed egress exit devices with 120V input, 12/24V output and 6A capacity, and the BEST RPSMLR2 is a supply for motorized latch retraction exit devices. The Command Access PS210 is a UL 6E/CSA linear supply with 1.5A at 24VDC and boost circuitry if the load needs a startup surge above its continuous rating.
5) What is the closest 24VDC 1 amp equivalent to the Detex 90-800 power supply?
The Command Access PS1 is the nearest match on output: it is a 24VDC linear power supply with 1 amp output, the same 1A current rating the Detex 90-800 carries. The Detex 90-800 converts 120VAC to 24VDC at 1.0A. Both land in the same slot for a single electrified lock or strike, with the Command Access unit built as a linear supply.
6) The Detex 90-800 is only 1 amp - what do I use when the load is bigger?
Step up through the SDC family, which is sized in stages on the same regulated and filtered DC concept: the SDC 631 is a 1.5 amp regulated and filtered DC power controller with dual voltage selection, the SDC 632 is the 2 amp version, and the SDC 634 is the 4 amp version. For a large multi-door head end, the Altronix AL1024ULACMCB gives 24VDC at 10A across 8 PTC outputs from a 115VAC 60Hz input. The Detex 90-800 itself is rated 1A.
7) My locks are 12VDC, not 24 - is the Detex 90-800 the wrong power supply?
The Detex 90-800 outputs 24VDC at 1.0A, so a 12V lock needs a different unit. Dual-voltage peers at similar output include the SDC 620, a 1 amp regulated and filtered low voltage supply with dual voltage selection, and the Securitron AQD1, a switching supply rated 12/24 VDC at 1 amp. The Adams Rite PS-1 is also 12/24 volts DC at 1 amp. Each lets you select the voltage in the field rather than committing to 24V at the order.
8) What do I use instead of the Detex 90-800 when I need to distribute power to several openings from one point?
The Detex 90-800 is a single 24VDC 1.0A supply. For multi-output distribution, the RCI DKPS-2A gives 8 outputs at 12/24VDC and 2A for access control systems, and the Altronix AL1024ULACMCB is a power supply and access power controller with 8 PTC outputs at 24VDC 10A in a grey enclosure. Both put the branch protection and the supply in one can rather than one supply per door.
9) The spec calls for a Grade 1 access control power supply - what is the alternative to the Detex 90-800?
The Von Duprin PS902 is a Grade 1 base power supply rated 2A at 12/24 VDC, field selectable, for access control. It gives you field voltage selection and twice the current of the Detex 90-800, which is fixed at 24VDC 1.0A from a 120VAC input.
10) What happens on a Detex 90-800 if one connected device shorts or draws too much?
Each output circuit is individually fused, and the fuses are field-resettable. A fault on one device trips only that circuit, so the rest of the system keeps running and a technician can restore it on site without swapping parts or shutting the whole supply down. There is also an On/Off switch on the unit for service and inspection.
11) What do I need to check on the electrical side before installing a Detex 800 Series power supply?
Confirm the feed is 120VAC and that the branch circuit has capacity for the 1.0A continuous load before you rough in. Kill power before you start, mount with service clearance, then land the fire alarm input circuit if emergency release is part of the sequence. Commission by verifying 24VDC output, fire alarm input response, and the LED status indicators.
12) What is the difference between the Detex 90-800 and the ROFU 9102 power supply?
The ROFU 9102-12D UL/9102-24D runs on 10/120VAC, 60Hz input and is offered in 12D and 24D output versions. The Detex 90-800 is fixed at 120VAC to 24VDC 1.0A and adds a dedicated fire alarm input that releases fail-safe locks during an alarm, individual field-resettable fused circuits, and an on/off switch for service.
13) Is the ROFU 10305-LA an alternative to the Detex 90-800 power supply?
No. The ROFU 10305-LA/10306-LA is a tamper resistant power transfer hinge rated 1.5A at 42V in a plastic white finish - it carries power across the gap from frame to door leaf, it does not generate it. The Detex 90-800 is the 120VAC to 24VDC source feeding that circuit. On an electrified opening you may well need both, one as the supply and one as the transfer path.
14) Is there a simpler plug-in power supply than the Detex 90-800 for a single door?
The ROFU 9126T is a plug-in mini power supply rated 12 VDC at 1.5A with a built-in time delay, so it needs no enclosure mounting or hardwired 120VAC run. It is 12V only. The Detex 90-800 is a hardwired 120VAC to 24VDC 1.0A unit in an 18-gauge steel enclosure with LED status indicators and a fire alarm input, which is the configuration a code-driven fail-safe opening calls for.
15) Is the BEST ELR150 the same kind of product as the Detex 90-800?
Not quite. The BEST ELR150 Series is a power supply control module for electronic access control - a control stage in the power path. The Detex 90-800 is the supply itself, converting 120VAC to 24VDC at 1.0A with a fire alarm input and field-resettable fused circuits. Check what the drawing is calling for before swapping one for the other.
16) Is there a way to power an access control opening where there is no 120VAC run, since the Detex 90-800 needs one?
The Detex 90-800 requires a 120VAC input to produce its 24VDC output. Where no AC run exists, the Securitron BPSS is a boxed solar power supply, which removes the branch circuit from the equation for remote gates and outbuildings. For bench testing a device before the permanent supply is in, the Command Access CAT Field Tester is a portable 12-24VDC supply that runs on DeWalt, Makita and Milwaukee batteries.
17) Should I use a switching or a linear power supply in place of the Detex 90-800?
Both types sit in the comparable range at similar output. Switching units include the Securitron AQD1 at 12/24 VDC 1 amp and the Securitron AQL4 at 12/24VDC 4/3 amp. Linear units include the Command Access PS1 at 24VDC 1 amp and the Command Access PS204/204B at 2A 24VDC with battery backup. The Detex 90-800 delivers regulated, filtered DC at 24VDC 1.0A from 120VAC. Match the type to what the lock manufacturer's instructions specify.
18) How do I tell if a Detex 800 Series power supply is working without pulling a meter on it?
LED system status indicators on the front give you the operating state at a glance, so a walk-by tells a maintenance tech whether the supply is live. Combine that with the On/Off switch and you can isolate and check the unit during an inspection round without meters or opening connections.
19) Is the Detex 90-800 enclosure rated for a commercial mechanical room or back-of-house install?
The enclosure is 18-gauge steel and the unit is classed commercial rather than residential, which is what you want in a mechanical room, electrical closet, or above-ceiling location in a school, hospital, or industrial building. Mount it with clearance for wiring access, ventilation, and future service.
20) Does the Detex 90-800 give clean regulated DC, or do I need a separate filter for card readers and controllers?
Output is regulated and filtered 24VDC, which is what electronic access control boards and readers need. No additional conditioning is required between the supply and the devices.
21) How many models do I have to choose from when ordering the Detex 90-800?
There is one configuration: model 90800, the 120VAC to 24VDC 1.0A unit with fire alarm input. No voltage jumper, output count, or enclosure option to specify on the order.
