Detex EAX-300W – Frequently Asked Questions

1) Will a door prop alarm work on an exterior door that gets rain and sun?
That is what the Detex EAX-300W is built for. The W is the weatherized housing, so it holds up on exterior openings where the unit sees weather. The standard indoor prop alarms in this class are not made for that exposure. It runs on a 9VDC battery, so there is no conduit or power run to get out to a remote exterior door either.
2) Can the Detex EAX-300W mount on a narrow stile aluminum storefront door?
Yes. The EAX-300W uses a compact tapered cover specifically so it can go on narrow stile doors where there is not enough face width for a full size housing. That makes it a common pick for aluminum and glass storefront entries.
3) How long can a door be held open before the EAX-300W alarm sounds?
The door open time is field selectable from 1 second to 4 minutes, and it ships set at 15 seconds. So a receiving door that legitimately stays open while a cart goes through can be stretched out, and a door you want locked down immediately can be pulled in to near-instant. You set it during setup, not at the factory, so one part number covers both cases.
4) Does the Detex EAX-300W need to be wired to a power supply or access control panel?
No wiring or power supply is required. The EAX-300W runs on a 9VDC battery and operates standalone, which is the whole reason property managers use it on doors that have no power nearby. It has a low battery alert so the unit tells you when the battery is going instead of failing quietly.
5) What is the difference between a door prop alarm and an exit alarm?
A prop alarm watches how long the door stays open. The EAX-300W lets people come and go, then sounds at 100 dB once the door has been held open past the set time, anywhere from 1 second to 4 minutes. An exit alarm instead sounds on any use of the door at all. If your problem is staff chocking a door open for a smoke break or a delivery, the prop alarm is the right tool; if you need to know every time the door is opened, you want a delay or exit alarm like the Dortronics 7281 Series, which is an exit alarm with a 2 to 60 second adjustable time delay.
6) What is the closest equivalent to the Detex EAX-300W door prop alarm from another manufacturer?
The Securitron DPA is the nearest straight equivalent. Both are dedicated door prop alarms built to sound when a door is held or propped open rather than to control the exit device itself. The Detex EAX-300W runs on a 9VDC battery with a 100 dB piezo alert and field-selectable door open time from 1 second to 4 minutes, with a 15 second default. Specify the EAX-300W where the door is exterior and the weatherized, tamper-resistant housing matters, and where a tapered cover is needed to fit a narrow stile.
7) I need a door prop alarm mounted in a single gang box next to the door instead of on the door. What should I use?
Use the Dortronics 7286 Series door prop alarm, which is furnished on a 1 gang plate with an LED and a piezo audio alarm, so it lands in a standard single gang box in the wall. The Detex EAX-300W is a self-contained unit that mounts at the door on a 9VDC battery, with a tapered cover sized for narrow stile doors and a weatherized housing for exterior openings. Choose by where the alarm needs to live: gang box in the wall, or on the door leaf with no wall device and no power run.
8) Is the Dortronics 7281 exit alarm a substitute for the Detex EAX-300W?
They answer different questions at the opening. The Dortronics 7281 Series is a door exit alarm with an adjustable 2 to 60 second time delay on a single gang plate with LED, built around delaying and annunciating an exit. The Detex EAX-300W is a door prop alarm: it monitors a door that may be used for egress or ingress but must not be held or propped open, timing the door open interval from 1 second to 4 minutes before the 100 dB piezo sounds. If the requirement is a propped-door alert rather than an exit delay, the 7281 is not the same device.
9) Is a 100 dB prop alarm loud enough to be heard in a warehouse or back hallway?
The EAX-300W puts out 100 dB through a piezo sounder. That is a local annunciation meant to be heard in the immediate area and to make propping the door uncomfortable, which is usually enough in a corridor, dock area, or retail back-of-house. It is a standalone local alarm, not a signal back to a security desk.
10) Will people be able to shut the prop alarm off or rip the cover off it?
The EAX-300W uses a secure, tamper-resistant housing that keeps the internals, including the battery, away from anyone trying to silence or bypass the unit. That matters on the doors these end up on, which are usually the unsupervised ones, back exits, stairwell doors, and exterior service doors where nobody is watching.
11) What are the alternatives to the Detex EAX-300W for an interior door prop alarm?
For interior openings where weather is not a factor and you have a gang box at the door, the Dortronics 7286 Series is a door prop alarm on a 1 gang plate with an LED and a piezo sounder, and the Securitron DPA is another door prop alarm option. Those are wall plate style devices, so they suit a finished interior wall next to the opening. The EAX-300W is the one to use when the door is exterior, has no power at it, or is a narrow stile door with the unit going on the door itself.
12) Can one Detex EAX-300W be used on several doors, or do I need a different model per opening?
One part number covers the range. The EAX-300W is a single model with no handing, size, or finish options to specify, and the door open time is set in the field from 1 second to 4 minutes rather than ordered. So a property manager standardizing across a dozen exterior doors orders the same unit for all of them and tunes the timing per opening at install.
13) I need a longer delay before the prop alarm sounds than 60 seconds. Which unit gives me that?
The Detex EAX-300W has field-selectable door open times from 1 second up to 4 minutes, with a 15 second default, so it covers loading dock and delivery doors where a minute is not enough. The Dortronics 7281 Series exit alarm carries an adjustable 2 to 60 second time delay. Set the EAX-300W timing during commissioning and document the setting for the facility record.
14) What is the difference between the Detex EAX-300W and the standard EAX-300 for my order?
The W is the weatherized build of the EAX-300 series. The Detex EAX-300W carries a weatherized, tamper-resistant housing for exterior openings exposed to the elements, with a tapered cover that fits narrow stile doors. Order under DTX-EAX-300W, model EAX-300W, and confirm the interior versus exterior location of each opening before you commit the count, since that is what decides which build belongs on the door.
15) How can staff tell whether the door alarm is armed before they walk away from it?
LED arming indicators on the unit show operational status at a glance, so a guard on rounds or a manager closing up can confirm the EAX-300W is armed without opening the cover. Combined with the low battery alert, that is the whole status picture on a battery unit.
16) Is the EAX-300W rated for commercial buildings or is it a residential product?
Commercial. The EAX-300W is specified for commercial security work, and it turns up on retail back doors, healthcare and school egress doors, industrial facilities, and government buildings. It is not a homeowner device.
