Detex 81-800 – Frequently Asked Questions

1) How many doors will the Detex 81-800 power supply run?
The Detex 81-800 controller and power supply is a one-door unit. It powers and controls the electric latch retraction (ER) device on a single door, with one signal output for one automatic door operator. If you have two or three ER openings to feed from one board, look at the other 800 Series controllers (82-800 and 83-800) instead of paralleling this one.
2) What input and output voltage does the Detex 81-800 need?
It takes 120VAC in and puts out filtered, regulated 24VDC at 1.0A continuous. Size the branch circuit for that 1.0A continuous load and confirm the hardware you are feeding is a 24V device, not 12V. There is no field-selectable 12/24V switch on this unit.
3) Will 1 amp be enough to run a Detex electric latch retraction exit device?
The 81-800 is the board Detex specifies for its own latch retraction devices with the ER electrified option, and it is rated 1.0A continuous at 24VDC for one such device. Latch retraction draws a heavy inrush on actuation, so this controller is matched to one ER device, not several. Adding a second retraction device to the same 1.0A output is where people get into trouble.
4) Can I tie an automatic door operator into the Detex 81-800?
Yes, that is one of the reasons to pick this board over a plain power supply. The 81-800 has a standard signal output for an automatic door operator, so retraction and the operator cycle can be sequenced from the same controller. One signal output, one operator.
5) Do I need the Detex 81-800 controller, or will a generic 24VDC 1A supply work?
If all you need is regulated low voltage for a strike, maglock or reader, a plain supply such as the Command Access PS1 (24VDC, 1 amp) or the SDC 620 Series (1 amp, regulated and filtered, dual voltage selection) will do it. The 81-800 is a logic and power supply controller: it also sequences the Detex ER latch retraction device and drives a door operator signal. Buy the 81-800 when the retraction logic and operator coordination matter, not just the voltage.
6) I need 12VDC instead of 24VDC for my access control devices - what should I use instead of the Detex 81-800?
The Detex 81-800 supplies 24VDC only. For a 12V option at a similar 1 amp capacity, the Securitron AQD1 is a switching power supply rated 12/24 VDC at 1 amp, and the Adams Rite PS-1 is a regulated 1 amp supply offering 12 or 24 volts DC with battery backup. Both let you select the output voltage rather than committing to 24VDC.
7) The Detex 81-800 is only 1 amp - what do I use if I need to power several electrified openings from one supply?
For higher capacity, the Command Access PS204/204B provides 2A at 24VDC with battery backup, the SDC 632 Series is a 2 amp regulated and filtered supply, and the SDC 634 Series steps up to 4 amps. The Von Duprin PS902 base power supply is 2A field selectable 12/24 VDC, and the Altronix AL1024ULACMCB combines a power supply and access power controller with eight PTC outputs at 24VDC and 10A. The Detex 81-800 is rated 1A continuous.
8) Is the Detex 81-800 the right supply for a motorized latch retraction exit device?
The Detex 81-800 is built to power Detex latch retraction exit devices with the ER electrified option, at 1A continuous 24VDC. If the exit device on the opening is a BEST motorized latch retraction device, the BEST RPSMLR2 Series is the power supply made for that family. Latch retraction devices draw a high inrush at actuation, so match the supply to the device brand and retraction type on the drawing.
9) Which products look like substitutes for the Detex 81-800 but are not power supplies for a fixed installation?
Two items in the same family are easy to mistake for it. The Command Access CAT Field Tester is a portable 12-24VDC supply that runs off DeWalt, Makita and Milwaukee batteries - a bench and field test tool, not a mounted building supply. The ROFU 10305-LA/10306-LA is a power transfer hinge rated 1.5A at 42V that carries current from frame to door; it supplies no power of its own. The Detex 81-800 is the 120VAC to 24VDC 1A controller and supply for the opening.
10) Does the Detex 81-800 include battery backup for power outages?
The board has an integrated battery charging circuit so the system keeps running through an outage, but the batteries themselves are not included. Order them separately and size them to your standby requirement.
11) What are the alternatives if I need a motorized latch retraction supply for another brand of exit device?
The 81-800 is built around Detex ER devices. For other manufacturers' retraction hardware, the BEST RPSMLR2 Series is a power supply made for motorized latch retraction exit devices, and the BEST ELR150 Series is a power supply control module for electronic access control. For delayed egress devices the BEST PS161-6 runs 120V in, 12/24V out at 6A.
12) I need more amperage or multiple protected outputs for a building-wide access control system. What should I look at instead?
One amp on a single door is the limit of the 81-800. For multi-point systems, the Altronix AL1024ULACMCB gives 24VDC at 10A across 8 PTC outputs from a 115VAC 60Hz input, and the RCI DKPS-2A offers 8 outputs at 12/24VDC, 2A. The Von Duprin PS902 is a 2A 12/24VDC field-selectable base supply. Use the 81-800 for the individual ER opening and a larger distributed supply for the rest of the system.
13) Will the Detex 81-800 work for a delayed egress exit device?
The Detex 81-800 is a controller and power supply for Detex ER latch retraction exit devices with a signal output for an automatic door operator. For delayed egress, the BEST PS161-6 is a power supply specified for delayed egress exit devices, with 120V input, 12/24V output and 6A capacity. Confirm the exit device manufacturer's listed supply before substituting, since delayed egress is a life safety function.
14) Do I need a UL listed power supply instead of the Detex 81-800 for a healthcare or school project?
If the specification calls out a UL listing on the face of the power supply, the Command Access PS210 is a UL 6E/CSA linear power supply with 1.5A at 24VDC output and boost circuitry, and the Aiphone AC-PS1250 is a UL listed 12V DC 5A supply for AC Series access control kits. The Detex 81-800 is a commercial-grade unit with filtered and regulated 24VDC output at 1A and an integrated battery charging circuit.
15) What is a smaller or simpler alternative to the Detex 81-800 for a single strike or maglock?
For a single low-draw device, the ROFU 9126T is a plug-in mini power supply rated 12 VDC at 1.5A with a built-in time delay, and the ROFU 9102-12D UL/9102-24D runs on 10/120VAC 60Hz input. Both are straight power sources. The Detex 81-800 is a controller as well as a supply, converting 120VAC to filtered regulated 24VDC at 1A with a battery charging circuit and a door operator signal output, so it suits openings that need operator coordination.
16) If I only need a control module added to an existing power supply, is the Detex 81-800 overkill?
The Detex 81-800 is a combined logic controller and power supply, converting 120VAC to 24VDC at 1A with an integrated battery charging circuit. If usable 24VDC is already present at the opening and you only need the switching logic, the BEST ELR150 Series is a power supply control module for electronic access control. Choose the 81-800 when the opening needs both the conversion and the operator signal output from one enclosure.
17) Does the Detex 81-800 come with the backup batteries, and what are the alternatives if I want backup handled differently?
The Detex 81-800 has a built-in battery charging circuit to keep the system running through an outage, with batteries purchased separately. The Adams Rite PS-1 is a 1 amp 12/24VDC regulated supply with battery backup, and the Command Access PS204/204B pairs 2A at 24VDC with battery backup. For an opening with no reliable line power, the Securitron BPSS is a boxed solar power supply.
18) How does the Detex 81-800 compare to a multi-output access power controller for a several-door system?
The Detex 81-800 handles one opening: 1A continuous at 24VDC with a signal output for one automatic door operator. For distributing power to multiple doors from a single cabinet, the RCI DKPS-2A offers eight outputs at 12/24VDC and 2A, and the Altronix AL1024ULACMCB is a power supply and access power controller with eight PTC outputs at 24VDC and 10A. A larger system is typically one controller per opening or one multi-output cabinet, depending on how the access control is wired.
19) Is a switching power supply a valid substitute for the Detex 81-800's filtered and regulated output?
The Detex 81-800 delivers filtered and regulated 24VDC, which protects connected circuitry from stray surges and voltage spikes. Switching alternatives include the Securitron AQD1 at 12/24 VDC 1 amp and the Securitron AQL4 at 12/24VDC 4/3 amp. On the linear side, the SDC 631 Series is a 1.5 amp regulated and filtered DC power controller with dual voltage selection. Check whether the electrified hardware specifies linear filtered power before switching topologies.
20) Is the Detex 81-800 suitable for a school or hospital, or is it a residential-grade unit?
Commercial-rated. The 81-800 is used in commercial building access control, schools, healthcare, retail, industrial, multi-tenant residential and government facilities. Filtered and regulated output protects connected electronics from stray surges and voltage spikes, which is what you want on a continuously powered opening.
21) Where can I get the wiring diagram for the Detex 81-800 before I rough in the conduit?
Detex publishes installation instructions for the 81-800, and a separate set covering the 82-800 and 83-800 multi-door controllers. Pull the 81-800 sheet for the 24VDC output terminals, the battery connections, and the door operator signal wiring, then mount the unit with clearance for wiring access, ventilation and future service.
