Detex EAX-300 GRAY W-CYL KA – Frequently Asked Questions

1) What does the Detex EAX-300 alarm actually do when someone props a door open?
The EAX-300 is a door prop alarm, not an exit alarm. The door can be opened and used normally for egress or ingress; the unit starts timing when the door opens and sounds a 100 dB piezo alarm only if the door is still open when the set time runs out. Default is 15 seconds, and the door open time is field selectable anywhere from 1 second up to 4 minutes. That makes it the right choice for a receiving door or a stairwell door that people legitimately pass through but that cannot be left blocked open.
2) What is the difference between the EAX-300 and the EAX-300 W-CYL with a cylinder?
The W-CYL version of the EAX-300 adds a key cylinder to the unit, so arming, disarming or silencing the alarm is controlled by key rather than being open to anyone standing at the door. If you have staff who need to shut the horn off or take the door out of service during deliveries, order the cylinder version. Without the cylinder you get the same prop timing and 100 dB horn but no keyed control at the device.
3) Will the EAX-300 prop alarm fit on a narrow stile aluminum storefront door?
Yes. The EAX-300 uses a smaller housing with a tapered cover specifically so it can be mounted on narrow stile doors, which is the usual problem on aluminum and glass storefront openings where there is very little flat stile to work with.
4) Do I have to run power to the EAX-300, or is it battery only?
Battery only. The EAX-300 runs on a 9VDC battery, so there is no conduit, no transformer and no wire pull to the opening, which is why it gets used on exterior and remote doors where getting power there would cost more than the device. It signals a low battery condition so you know when to swap it, and LED indicators show arming status at a glance.
5) Is there a weatherized EAX-300 for an exterior door?
The EAX-300 with cylinder comes two ways: standard gray, and gray weatherized. Pick the weatherized build for doors exposed to rain, wind driven moisture or wash down, such as loading docks, exterior stair discharge doors and gates. For interior corridor, stairwell and stockroom doors the standard gray unit is what you want.
6) Can a property manager use the EAX-300 on a fire exit door without blocking egress?
Yes, and that is the point of it. The EAX-300 does not lock or latch anything. It only monitors how long the door stays open, so free egress through the door is unaffected and the alarm is what discourages people from chocking it. If you need the door itself secured or alarmed against unauthorized exit, that is a different device class, an exit control lock rather than a prop alarm.
7) How do I set the door open time on a Detex EAX-300 after it is mounted?
The timing is field selectable on the unit itself, so it is set during install rather than ordered as a factory option. Mount the unit, choose the door open time anywhere from 1 second to 4 minutes (it ships at 15 seconds), then test normal open and close, the alarm trip and the low battery alert before you close it up. Detex publishes the EAX-300 installation instructions, and the EAX-300 series catalog page, as downloadable PDFs.
8) Will a 100 dB alarm be loud enough to be heard if the door is at the far end of the building?
The EAX-300 sounds locally at the door at 100 dB. It is a deterrent at the opening, meant to be heard by the person propping it and anyone nearby, not a building wide annunciator. If the door is remote and nobody is near it, pair the prop alarm with your access control or monitoring system for remote notification, because the EAX-300 on its own is a standalone battery device at the door.
9) Is the EAX-300 rated for commercial use or is it a residential alarm?
Commercial. Detex builds the EAX-300 for commercial duty with a secure, tamper resistant housing that keeps the internals out of reach in high traffic spaces. Typical placements are schools, hospitals, retail back of house, industrial plants and government buildings.
