Detex 12-800 – Frequently Asked Questions

1) How many doors will one Detex 12-800 logic controller run?
One 12-800 controller handles up to two doors for standard egress or a 2-door interlock. Delayed egress is the exception: each independent delayed egress opening needs its own controller, so two delayed egress doors that operate separately means two 12-800 units.
2) Does the Detex 12-800 put out 12VDC or 24VDC for my electric lock?
Either. The 12-800 takes 120VAC in and is field selectable between 12 and 24VDC output, and it delivers at least 2A of DC power at the door. There is also a separate 9VDC, 100mA tap on the terminal strip for auxiliary devices.
3) Does the battery come with the Detex 12-800, and how long does it hold the doors up?
Battery is not included. The 12-800 has the backup and charging circuit built in as standard and will carry the load for up to 4 hours once you add the battery, so budget for that battery as a separate line item on the order.
4) Can I tie the Detex 12-800 into my fire alarm for delayed egress release?
Yes. The 800 Series controller provides multiple fire alarm relay input options so it can be wired to release on alarm per the life safety code that applies to your building, and it carries local and remote alarm output relays in the same box. Relay connections can be configured wet or dry.
5) Do I need a Detex logic controller, or will a plain 2 amp access control power supply do the job?
If all you need is 24VDC to a strike or maglock, a straight supply such as the Von Duprin PS902 (2A, 12/24VDC field selectable) or the SDC 632 (2 amp, dual voltage) is the simpler buy. The 12-800 is a logic controller as well as a supply: it processes switch, access control, and dry contact inputs into timed egress, delayed egress, and 2-door interlock sequences with alarm relays on board. Buy it when the sequence matters, not just the power.
6) What is a comparable power supply to the Detex 12-800 for a delayed egress exit device?
The Detex 12-800 Series logic controller runs on 120VAC input with 24VDC output, includes a battery backup and charging circuit, and controls up to two doors for standard egress, delayed egress, or two-door interlock. The closest peer aimed at the same duty is the BEST PS161-6, a power supply for delayed egress exit devices with 120V input, 12/24V output and 6A capacity. The BEST unit is a higher-current supply; the Detex adds the logic side, processing switch, access control, or dry contact inputs into relay outputs for locks, local alarm, and remote alarm.
7) If I only need to power a maglock and do not need delayed egress logic, what should I use instead of the Detex 12-800?
The Detex 12-800 is a combined logic controller and power supply that processes inputs into lock, local alarm, and remote alarm relay outputs for up to two doors. If the job is straight power with no control logic, a plain regulated supply covers it: the Von Duprin PS902 base power supply is 2A at 12/24VDC field selectable for access control, the SDC 632 is a 2 amp regulated and filtered low voltage supply with dual voltage selection, and the Command Access PS204/204B is a linear supply with 2A at 24VDC and battery backup. All three match the Detex on output current class; none of them include the two-door egress logic.
8) I need to power more doors than the Detex 12-800 handles. What is the higher-capacity option?
The Detex 12-800 supplies at least 2A of DC power at the door and controls up to two doors. For larger door counts off one enclosure, the Altronix AL1024ULACMCB is a power supply and access power controller with 115VAC 60Hz input at 4.2A, eight PTC outputs and 24VDC at 10A, and the RCI DKPS-2A offers eight outputs at 12/24VDC and 2A. The SDC 634 is a 4 amp regulated and filtered supply with dual voltage selection. These are distribution supplies rather than delayed egress controllers, so the egress timing and alarm relays would come from separate hardware.
9) Will the Detex 12-800 accept inputs from my card reader or access control panel?
That is what it is built for. The 12-800 is a universal logic controller: it takes inputs from switches, an access control system, or any dry contact device and converts them into the outputs you need, driving lock relays plus local and remote alarm relays. Wiring lands on a factory-labeled 24-point terminal strip.
10) What actually comes in the Detex 12-800 box?
You get the back box, upper back pan, flip-up insert, the 24-point terminal strip, the transformer, and the Series 800 electronics, all prewired at the factory with labeled connections. The unit also has an inline fuse and an on/off switch for service. The backup battery is the piece you buy separately.
11) What other 2 amp supplies with battery backup are close to the Detex 12-800?
On the power side, the Command Access PS204/204B is a linear supply with 2A at 24VDC and battery backup, the RCI DKPS-2A gives 12/24VDC at 2A across 8 outputs, and the Adams Rite PS-1 is a 1 amp 12/24VDC regulated supply with battery backup. They match or approach the current, but none of them carries the 800 Series delayed egress and 2-door interlock logic.
12) Which alternative to the Detex 12-800 gives me battery backup already built in?
The Detex 12-800 carries a standard battery backup and charging circuit good for up to four hours, with the battery sold separately. Peers that also list onboard battery backup are the Command Access PS204/204B, a linear supply at 2A/24VDC with battery backup, and the Adams Rite PS-1, a 1 amp regulated supply at 12/24VDC with battery backup. The Adams Rite unit is the lower-current option of the three, and neither peer includes the Detex two-door egress and interlock control.
13) Is the Command Access CAT Field Tester a substitute for the Detex 12-800?
No. The Detex 12-800 is a permanently mounted 120VAC/24VDC logic controller and power supply with a back box, 24-point terminal strip, transformer, and factory prewiring for up to two doors. The Command Access CAT Field Tester is a portable 12-24VDC power supply that runs off DeWalt, Makita and Milwaukee batteries, intended for bench and field testing of devices rather than serving as the installed power source at the opening.
14) What is the difference between the Detex 12-800 and a motorized latch retraction power supply like the BEST RPSMLR2?
They solve different problems. The BEST RPSMLR2 is a power supply built for motorized latch retraction exit devices, which draw a high inrush current when the motor pulls the latch. The Detex 12-800 is a logic controller and 120VAC/24VDC supply for standard egress, delayed egress, and two-door interlock, delivering at least 2A at the door with relay outputs for locks and local and remote alarms. If the exit device on the opening is a motorized latch retraction unit, specify the supply intended for that load.
15) Can I use a plug-in mini supply like the ROFU 9126T in place of the Detex 12-800?
Only where the application is a single low-current 12VDC device with a simple delay. The ROFU 9126T is a plug-in mini power supply rated 12 VDC at 1.5A with time delay. The Detex 12-800 is a hardwired 120VAC unit in a back box with a transformer, 24-point terminal strip, inline fuse protection, an on/off service switch, status LEDs, and a battery backup circuit, controlling up to two doors for delayed egress or interlock. The two are not interchangeable on a delayed egress opening.
16) Is the ROFU 10305-LA a substitute for the Detex 12-800?
No. The ROFU 10305-LA/10306-LA is a tamper resistant power transfer hinge rated 1.5A at 42V in a plastic white finish, used to carry conductors from the frame into the door leaf. The Detex 12-800 is the 120VAC/24VDC logic controller and power supply that feeds that circuit. On an electrified opening you may well need both, but the hinge does not replace the controller.
17) I need a UL listed supply for an access control kit. How does the Aiphone AC-PS1250 compare with the Detex 12-800?
The Aiphone AC-PS1250 is a UL listed 12V DC 5A supply matched to Aiphone AC Series access control kits, so it is the right call when the head end is that system and the load is 12V. The Detex 12-800 is a 120VAC/24VDC logic controller that accepts inputs from switches, access control systems, or dry contacts and drives lock, local alarm, and remote alarm relays for up to two doors, with a 9VDC 100mA auxiliary tap and battery backup circuit. Pick the Detex when the opening needs delayed egress or interlock control rather than kit-matched power alone.
18) What alternative to the Detex 12-800 works where there is no 120VAC available?
The Detex 12-800 requires a 120VAC input to produce its 24VDC output, so it needs line power at the enclosure. Where no AC feed exists, the Securitron BPSS is a boxed solar power supply. Confirm the solar unit's output suits the lock and control devices at the opening, since it does not provide the Detex two-door delayed egress logic or the lock and alarm relay outputs.
19) Is the Detex 12-800 suitable for a school or hospital, or is it a light commercial unit?
It is a commercial-rated electronic access control device, and the intended uses run to educational safety systems, healthcare access control, commercial building security, industrial facilities, and delayed egress code compliance. The status LEDs and numbered, text-labeled circuits make it something a facilities crew can troubleshoot without a wiring print in hand.
20) Where do I get the wiring diagram for the Detex 800 Series controller?
Detex publishes installation instructions for the 80-800 and 90-800 configurations, and both PDFs are provided with the 12-800 record. They carry the wiring diagrams, relay configuration for wet or dry operation, the 12/24VDC selection, and troubleshooting steps you will want before you land wire on the 24-point strip.
