Detex EAX-3500 – Frequently Asked Questions

1) What's the difference between the Detex EAX-3500, EAX-3500FK and EAX-3500SK?
They're the same alarm packaged three ways. EAX-3500 is the device only, so you supply the magnetic door contacts and a 24V transformer. EAX-3500SK is the surface kit, shipping with surface door contacts and a plug-in transformer. EAX-3500FK is the flush kit, shipping with flush door contacts and a plug-in transformer. Flush contacts get mortised into the door and frame edge for a concealed look; surface contacts screw onto the face and are the faster retrofit.
2) Do I need to run power to a Detex EAX-3500 exit alarm, or does it run on batteries?
It has to be wired. The EAX-3500 is a hardwired low voltage unit running on 12 to 24 VAC, and the catalog lists it as not battery operated. The rechargeable battery inside is backup only, good for 72 hours of continuous operation if the power drops, and the unit warns you when that battery is getting low. If you want the transformer in the box, order the SK or FK kit version, which includes a plug-in transformer.
3) Do I have to order a cylinder separately for the Detex EAX-3500?
That's your call at order time. Three choices: None, if you already have a cylinder or don't need keyed control; MC65 mortise cylinder, if you want a standard keyed cylinder supplied; or the IC7 7-pin interchangeable core housing, which takes your own small format core so the alarm falls into the building's existing IC keying. Note the IC7 option is the housing only, the core isn't included, so a locksmith standardizing a property still has to pull a core from stock.
4) How does the timed bypass work on the Detex EAX-3500, and can staff leave it turned off?
A manager keys the unit into bypass so the door can be used for a delivery or maintenance without setting off the horn. The bypass is timed, and the system rearms automatically when the door closes, so nobody can quietly leave the alarm disabled the way they can with a simple on/off switch. That's the main reason property managers pick this over a plain armed/disarmed exit alarm.
5) What else do I need to buy to finish installing a Detex EAX-3500?
If you order the bare EAX-3500, plan on magnetic door contacts and a 24V transformer, plus low voltage wire of the right gauge and a power run to the opening. Order the SK or FK kit instead and the contacts and plug-in transformer come with it. Either way you'll want clearance at the mounting location for wiring access and future service.
6) How loud is the Detex EAX-3500 alarm, and is it loud enough for a warehouse or retail floor?
100 decibels. That carries across a sales floor, a stockroom or a loading area, which is why it gets specified for retail loss prevention, warehouses and distribution centers. It's a commercial-rated unit, not a residential doorchime.
7) What happens to the Detex EAX-3500 during a power outage?
It keeps running. The rechargeable backup battery carries the unit for 72 hours of continuous operation, so the door stays monitored through a typical outage, and the low battery alert gives you warning ahead of a battery replacement rather than a silent failure. That matters in healthcare and institutional settings where an unmonitored exit for a day isn't acceptable.
8) Can I get the Detex exit alarm sign in Spanish or French?
Yes. Signage is an add-on choice with seven versions: red with white letters in English, Spanish or French Canadian, and green with white letters in English, German, Chinese, or German/English. Useful on multi-language campuses and hospitality properties where the exit warning has to be readable by everyone using the door.
9) Is there an installation manual for the Detex EAX-3500 flush mount kit?
Yes, the EAX-3500FK flush mount kit has its own installation instruction sheet separate from the standard one, and there's a general installation sheet covering units built after July 1, 2017, plus the catalog page. Worth checking which sheet applies if you're servicing an older unit already on the door, since the instructions changed at that 2017 cutoff.
