Detex EAX-300 BLACK – Frequently Asked Questions

1) Will a Detex EAX-300 door prop alarm fit a narrow stile aluminum storefront door?
Yes. The EAX-300 uses a compact housing with a tapered cover specifically so it can go on narrow stile doors where there isn't room for a full-size exit alarm. It's battery powered off a 9VDC cell, so there's no wiring to run to the door either, which is the other thing that usually kills a storefront install.
2) What's the difference between the Detex EAX-300 door prop mode and door chime mode?
You pick one at order time. In Door Prop mode the EAX-300 stays quiet while the door swings normally and only sounds the 100 dB piezo once the door has been held open past the set delay. In Door Chime mode it signals on the door opening itself, so you hear every entry rather than only the abuse. Prop mode is what you want on a fire exit or a back delivery door that keeps getting blocked with a brick; chime mode is for a door you want announced, like a back-of-house entrance staff use all day.
3) How long can a door be held open before the Detex EAX-300 alarm sounds?
The door prop delay is a factory-set option on the EAX-300, and you choose it when you order: 1 second, 15 seconds, 30 seconds, 45 seconds, 60 seconds, 2 minutes, or 4 minutes 15 seconds. Fifteen seconds is the standard setting and works for a door people walk through; if you have a loading door where carts go in and out, go to 60 seconds or 2 minutes or you'll be listening to the alarm all afternoon.
4) Can you put a Detex EAX-300 prop alarm on an exterior door that's exposed to weather?
There's a weatherized version of the EAX-300, and that's what you specify for an exterior opening, a dock door, or anywhere the unit takes rain or washdown. Note that the SK1 through SK6 surface mounting kits are for the non-weatherized unit only, so a weatherized order is a door-mounted unit rather than a wall-mounted one.
5) How do you shut off a Detex EAX-300 alarm once it's sounding, and can staff key it off?
The EAX-300 is ordered with or without a cylinder, and the cylinder is how authorized staff arm, disarm, and silence it. Three cylinder options: a 7-pin IC housing (IC7) or an InstaKey housing (IK7), both of which ship without the core so you supply your own to match the building's keying, or an MC65 mortise cylinder supplied complete. If your facility is already keyed on a small format interchangeable core system, take the IC7 and drop your own core in so the unit falls under the existing master key. You can also order it with no cylinder at all.
6) Does the Detex EAX-300 need to be wired to power or to a panel?
No wiring. The EAX-300 runs on a single 9VDC battery and has its own low battery alert, plus LED arming indicators so you can see the unit is live without opening it. That's the whole reason to pick this over a hardwired exit alarm: no conduit, no transformer, no trip charge for an electrician. Budget a battery change into your PM rounds, since the alarm is only as good as the cell in it.
7) Will a Detex EAX-300 stop tenants from disabling it or pulling the battery?
The EAX-300 housing is tamper-resistant and closes over the battery as well as the internals, so someone can't just pop the cover and pull the cell to kill the alarm. Paired with the cylinder option, only a keyholder gets into it. That matters most on multi-tenant residential and back-of-house doors, which are exactly the openings people prop.
8) Is the Detex EAX-300 an exit device, or does it lock the door?
Neither. The EAX-300 is a monitoring alarm, not a lock and not a panic device. It watches the door with magnetic contacts and sounds a 100 dB piezo when the door is held open past the set delay. The door still needs its own latching hardware or exit device. Use the EAX-300 where the opening is legitimately used for egress or ingress but must not be propped, and where you want to know about it without adding an access control system.
9) What is the key stop option on the Detex EAX-300 and do I need it?
Key stop is a yes/no choice when you order the EAX-300. It changes how the key behaves in the cylinder, and it's the sort of thing to match across a building rather than mix. If you're adding units to openings that already have EAX-300s, order the new ones the same way as the existing units so every door operates identically for your staff.
10) Can I get a Detex EAX-300 with Spanish or French signage for the door?
Signage is an add-on when you order. Seven choices: red with white lettering in English, Spanish, or French Canadian, and green with white lettering in English, German, Chinese, or German/English. Useful if your facility posts bilingual notices or you're working to a Canadian or multilingual site standard. It's optional, so the unit can also be ordered without any sign.
11) Is the Detex EAX-300 available in a finish that will blend with a dark storefront frame?
Two finishes on the EAX-300, black and gray. Black is the one that disappears against a dark anodized aluminum storefront frame; gray suits a clear anodized or painted hollow metal opening. Same unit either way, so pick on appearance.
12) Is the Detex EAX-300 rated for commercial use in a school or hospital?
The EAX-300 is a commercial-duty product, and the applications it's built for are institutional: schools, healthcare facilities, retail, industrial plants, multi-tenant residential, and government buildings. If you're standardizing across a campus, the practical move is to fix one configuration (delay, mode, finish, cylinder type) and order every opening the same way so maintenance carries one spare and staff learn one procedure.
