Detex EAX-411SK – Frequently Asked Questions

1) How do I stop staff and delivery drivers from propping open a back door?
A door prop alarm is the standard fix, and the Detex EAX-411SK kit is built for exactly that. Surface magnetic switch contacts watch the door, and if it stays open past the time you set, a local alarm sounds at the opening so anyone nearby hears it. Close the door and the unit resets and rearms itself, so nobody has to go silence it or reset a switch. It also has an alarm status relay output, so the same event can annunciate at a guard desk or in an access control zone rather than just at the door.
2) How long can a door stay open before the Detex EAX-411SK alarm sounds?
You set it. The door open timing is adjustable from 0 to 60 seconds, so a loading dock that legitimately stands open for a minute gets a long setting and a secured stairwell or perimeter door gets a short one. Same unit either way, adjusted at install per opening.
3) What power does the Detex EAX-411SK door prop alarm need, and does it run on batteries?
This one is AC powered, not battery. It runs on 24VAC and the kit ships with the 24VAC transformer, so you need line power available at or near the opening to feed that transformer. If the door you are securing has no power run to it and you do not want to pull one, an AC powered prop alarm is the wrong choice for that opening.
4) What comes in the Detex EAX-411SK kit and what else do I need to buy?
The kit covers the alarm itself plus a back box, surface magnetic switch contacts, and the 24VAC transformer. What it does not include is the building side of the job: line voltage to the transformer, the wire between the unit and the contacts, connectors, and anything you need for the relay run if you are tying it back to an access control panel or annunciator.
5) Where does the Detex EAX-411SK mount, and do I have to cut into the door?
Nothing gets cut into the door. The unit mounts in a standard 1 gang electrical box, and the kit includes a back box for surface work. Detection is by surface magnetic contacts, so one leaf goes on the door and the other on the frame, no mortising and no drilling through the door. That makes it workable on doors you cannot modify, including hollow metal openings already hung.
6) Do I want a door prop alarm or an alarmed exit device on this door?
Two different problems. A door prop alarm like the EAX-411SK watches how long the opening stays open and sounds after your set delay, up to 60 seconds, which is what you want on a door that is supposed to be used, just not held open: a dock door, a service entrance, a delivery route. An alarmed exit device sounds on the fact of the exit itself, which is what you want on a door nobody is supposed to go through at all. If the complaint is a wedge under the door, the prop alarm is the right tool.
7) Can the Detex EAX-411SK tie into our existing access control system?
Yes, through the alarm status relay output. That contact is what you take back to an access control panel or annunciator so the prop condition shows up as a monitored zone at the head end, not only as a horn at the door. The local alarm still sounds at the opening either way, so on site staff get the alert whether or not anyone is watching the panel.
8) Does someone have to reset the Detex EAX-411SK after every alarm?
No. Closing the door resets and rearms the unit automatically. That matters if you are standardizing across a building with a lot of doors, since a unit needing a manual reset generates a maintenance call every time a driver holds a door too long. Set the delay once at install and it manages itself from there.
9) Is the Detex EAX-411SK rated for commercial use or is it a residential product?
Commercial. It is specified for commercial door hardware use, which is why it is built around 24VAC power, standard gang box mounting, and a relay output for panel integration rather than a self contained residential chime.
10) Where can I get wiring diagrams for the Detex EAX-411SK before we bid the job?
Detex publishes both a catalog page and full installation instructions for the EAX-411SK, and the instructions carry the wiring diagrams, timing adjustment, and testing procedure. Worth pulling before you price the electrical, since the 24VAC transformer needs a line voltage source at the opening and that run is usually the real cost on the job, not the device.
