Detex DTX-12800-DE – Frequently Asked Questions

1) How many doors will a Detex 12-800 controller run on a delayed egress opening?
One. The 12-800 handles up to 2 doors for standard egress or interlock setups, but delayed egress takes one controller per opening. So a pair of delayed egress doors means two controllers, not one board split between them. Plan the panel locations and the 110VAC feeds accordingly.
2) Can one power supply run both 12 volt and 24 volt hardware on the same job?
No. Output on the 12-800 is selectable, 12VDC or 24VDC, and you set it one way for the whole unit at 2 amps. If you have a 24V mag lock and a 12V reader power feed on the same opening, that is either a second supply or a separate step-down, not a second output from this board. What the selector does buy you is one part number that covers either voltage, so you are not stocking two controllers.
3) How far can the Detex 12-800 be mounted from the door it controls?
Up to 100 feet, using 18-gauge stranded wire for the door connections. That covers most electrical-room-to-opening runs, but if the panel location is farther out than 100 feet you need to move the controller closer rather than upsize the wire and hope.
4) Does the Detex 12-800 release the door on a fire alarm?
Yes, fire alarm override is built in, and the unit is UL listed both as a power supply and as a special locking arrangement for delayed egress. That override is what makes a delayed egress opening code compliant: the alarm input drops the lock immediately instead of running the egress timer. Wire the override to the FACP before you sign off on the opening.
5) How long does the Detex 12-800 hold a delayed egress door secure if the building loses power?
Up to 4 hours, through the integrated battery backup circuit. The battery itself is an option, not part of the base unit, so add one to the order if you need standby, otherwise the opening reverts to whatever the hardware does unpowered as soon as the feed drops.
6) Is the Detex 12-800 an exit device, or do I still need a panic bar on the door?
It is a logic controller and power supply in a wall-mounted enclosure, not door hardware. You still need the exit device on the leaf, plus the lock or mag lock being controlled. The 12-800 provides the power, the delayed egress timing, the fire alarm override, and the relay logic behind it.
7) Can the Detex 12-800 controller be used in place of a vertical rod exit device on a delayed egress opening?
No. The Detex 12-800 Series is a logic controller and regulated power supply, with selectable 12VDC or 24VDC output at 2 amps, relay outputs and fire alarm override; it provides the control and power behind a delayed egress opening, not the latching hardware on the door. The door still needs a panic device such as the Von Duprin 8827-3FT wide stile surface vertical rod exit device or the Marks USA M9900VR 36 in x 84 in vertical rod panic device. The 12-800 and the exit device are ordered together, not one instead of the other.
8) If an opening only needs free egress and no delayed egress, what is used instead of a Detex 12-800?
A mechanical exit only vertical rod device needs no controller or power at all. The Cal-Royal 9860 is a heavy duty Grade 2 surface vertical rod device, exit only, and the Imperial USA ED-VR531 from the ED-500 Series is a Grade 1 wide stile surface vertical rod device at 36 in, also exit only. The Detex 12-800 Series is only required where the opening is running delayed egress, an interlock, or electrified locking that needs regulated 12VDC or 24VDC power and relay logic.
9) What is the difference between the DE1 and DE2 options on the Detex 12-800?
They are the two order configurations of the 12-800 logic controller and power supply, specified as Types DE1 and DE2 at the time of order. Pick the one that matches the delayed egress arrangement you are wiring, since the controller itself is the same dual-voltage 12VDC/24VDC 2 amp unit either way.
10) What can I switch off the relays on a Detex 12-800, and will they drive a mag lock and a horn?
There are multiple programmable relays with wet or dry contact configuration: 2A for locks, 5A for alarms, plus outputs for access control integration. A single mag lock or electric lock sits inside the 2A lock rating, and a local horn or sounder goes on the 5A alarm relay. Add up the actual inrush of everything you are hanging on the board against the 2 amp supply output, not just the relay ratings.
11) Will the Detex 12-800 work with exit alarms and electric locks that aren't Detex?
It is a regulated power and logic source for electrified hardware generally, listed as compatible with delayed egress systems, access control hardware, and Detex panic devices. Anything that takes 12VDC or 24VDC within the 2 amp budget and switches on a dry or wet contact can be driven from it. What it will not do is supply a voltage it doesn't output, so confirm the lock or alarm you are pairing it with runs on 12 or 24 volts DC.
12) Can I use the Detex 12-800 to build an interlock between two doors so only one opens at a time?
Yes. Interlock is one of its standard applications, and it manages up to 2 doors in that mode, which is what an interlock needs: both leaves on one logic board so the controller can hold one while the other is released. This is the common arrangement for vestibules, labs, and server rooms. Delayed egress is the mode that drops to one door per controller.
13) I need a panic device for a pair of doors, not a power supply. What vertical rod exit devices are there?
The 12-800 is the controller, so for the leaf itself look at surface vertical rod devices. Fire rated options include the Delaney F9100 Series and the Marks USA M9900FVR in 36 x 84 and the M9900F-VR in 48 x 84. Non fire rated Grade 1 choices include the Von Duprin 8827-3FT wide stile device for 1-3/4 inch doors, the Imperial USA ED-VR531 wide stile in 36 inch, and the Delaney 8100 and 9100 Series. The Cal-Royal 9860 is a Grade 2 heavy duty exit only device. If the opening is fire rated, the rating is not optional, so start from the F9100, M9900FVR, or M9900F-VR.
14) What do I need to check on site before installing a Detex 12-800?
Confirm 110VAC input power is available at the mounting location with enough current capacity, and that you have clearance around the enclosure for wiring access, ventilation, and later service. Then verify the door run is inside 100 feet so 18-gauge stranded will do the job. The enclosure arrives pre-wired with labeled terminal strips, so the field work is the feed, the door wiring, and setting voltage and timing.
15) How many Detex 12-800 controllers are needed for a two door delayed egress bank, and what devices go on the doors?
The 12-800 Series manages up to 2 doors for standard egress and interlock applications, but delayed egress calls for one controller per opening, so a two door delayed egress bank takes two controllers. Each leaf still carries its own vertical rod device sized to the opening: 36 in x 84 in options include the Delaney 8100 Series Grade 1 vertical rod device and the Marks USA M9900VR, while a 48 in x 84 in leaf takes the Marks USA M9900VR 48 in x 84 in vertical rod panic device.
16) Is there any tamper protection on the Detex 12-800 enclosure?
A tamper switch is included, and a cover lock key is available as an option. On a delayed egress opening that matters more than it sounds: the controller is the thing holding the door, so an unsecured cover in a public corridor is the weak point. Specify the cover lock where the panel is anywhere a tenant or the public can reach it.
17) How do I know the Detex 12-800 is working after a delayed egress test?
Status LEDs on the board give direct visual feedback on system operation for commissioning and troubleshooting. When you test the opening, run normal operation, the alarm function, battery backup, and the fire alarm override, then document the voltage selection and timing settings you configured so the next tech is not guessing.
18) Does a Grade 1 vertical rod device change what the Detex 12-800 has to supply?
No. The 12-800 Series output is selectable 12VDC or 24VDC at 2 amps with relay contacts rated 2A for locks and 5A for alarms, and that sizing is driven by the electrified hardware draw rather than the mechanical grade of the device. Grade 1 vertical rod peers such as the Von Duprin 8827-3FT in the 88 Series and the Delaney 9100 Series differ from the Grade 2 Cal-Royal 9860 in mechanical duty rating, which is a specification for the door leaf and traffic, not for the power supply feeding the opening.
