Detex EAX-500 BLACK W-CYL KA – Frequently Asked Questions

1) Will the Detex EAX-500 exit alarm fit a narrow stile aluminum storefront door?
Yes. The EAX-500 uses a tapered cover specifically redesigned to clear narrow stile doors, so it mounts on aluminum storefront and glass front openings as well as wide stile hollow metal. That tapered profile is the main physical difference between it and a boxier surface alarm that overhangs the stile edge.
2) Do I have to specify left hand or right hand when ordering a Detex EAX-500?
No handing to specify. The EAX-500 circuit senses where the external magnet sits and sets the door handing itself, so one unit covers either hand and can be re-handed in the field if the door swing changes. That is why the ordering choices are limited to finish, keying, and whether you want the weatherized version.
3) Does the Detex EAX-500 need to be wired to building power?
No. The EAX-500 runs on a single 9VDC battery with a low battery alert, so there is no transformer, no power supply, and no conduit run to the door. That makes it the practical choice on a glass storefront door or a remote exterior exit where pulling power is the expensive part of the job. Plan on battery replacement as part of your PM route.
4) What do I order to key several Detex EAX-500 exit alarms alike across a building?
Keyed alike is a build option on the EAX-500, so a property manager standardizing a fleet of exit doors orders every unit keyed alike and one control key silences and arms all of them. Keyed different is the other choice, for tenants or departments who should only reach their own door. The key is what silences the alarm, so keying decides who can shut it off.
5) Can the Detex EAX-500 go on an exterior door exposed to weather?
Order the weatherized version for that. The EAX-500 is built in both a standard and a weatherized configuration, and the weatherized one is what belongs on an exterior rear exit, a loading dock door, or an unconditioned stairwell. Both configurations come in black and gray.
6) Should I use a self-contained exit alarm like the Detex EAX-500 or a full panic bar with a built-in alarm?
Two different jobs. The EAX-500 is a self-contained alarm unit that mounts alongside whatever exit hardware is already on the door, so you keep the existing panic device and only add unauthorized-exit detection. If the door needs the exit hardware itself replaced, an alarmed exit bar such as the Alarm Lock 700 or 710 Series Sirenlock, both 36 inch panic exit alarm devices, does the latching and the alarm in one unit. Adding to a good existing device favors the EAX-500; a tired or missing device favors the bar.
7) Will the Detex EAX-500 hold someone at the door for 15 seconds before releasing?
No. The EAX-500 is an alarm, not a delayed egress device: it sounds a 100dB horn when the door is opened but does nothing to hold the door. If your local authority permits delayed egress and you need the door to stay latched for the delay period, you need a delayed egress product such as the Alarm Lock Sirenlock 715, which is built for that function. Do not substitute an alarm where the drawing calls for delayed egress.
8) What is the closest alternative to the Detex EAX-500 exit alarm from another manufacturer?
The Alarm Lock Sirenlock 250 panic exit alarm is the nearest peer in intent. Both are exit alarms mounted on a secured door to signal unauthorized egress. The differences a specifier cares about: the EAX-500 sounds a 100dB piezo horn and runs on a 9VDC battery with a low battery alert, so no hardwired power run is needed, and its circuit senses the external magnet location and sets door handing automatically. The Sirenlock 250 uses a 95dB dual tone siren and is supplied in a US28 aluminum finish. The EAX-500 is offered in black and gray, keyed alike or keyed different, with a weatherized option for exterior openings.
9) I need an exit alarm for an outdoor door that is not on a power circuit. Which one works?
The Detex EAX-500 is the one to specify for that opening. It runs on a 9VDC battery with a low battery alert, so it needs no hardwired power connection, and it is ordered with a weatherized option for exposed exterior doors. The Alarm Lock Sirenlock 250, 700, 710 and 715 exit alarms are the other units in this class, but the weatherized build and the battery-only operation belong to the EAX-500. Keying is chosen as keyed alike across a group of doors or keyed different per door, in black or gray.
10) The fire marshal is requiring delayed egress on our stairwell door. Will a Detex EAX-500 satisfy that?
No. The EAX-500 is an exit alarm: it sounds a 100dB piezo horn when someone pushes the door, and the alarm is silenced with the control key, but it does not hold the door for a delay period. For a delayed egress opening, the Alarm Lock Sirenlock 715 is the unit built for that function, a 36 inch delayed egress exit alarm in US28 aluminum with a 95dB dual piezo system. Use the EAX-500 where the requirement is to detect and announce an unauthorized exit rather than to delay it.
11) How loud is the Detex EAX-500 alarm and is it enough for a retail floor?
The piezo horn sounds at 100dB, which carries across a sales floor or a warehouse aisle over normal background noise. Among comparable surface exit alarms, the Alarm Lock Sirenlock 250 and 700 Series units run a 95dB dual tone siren, so the EAX-500 is a few decibels hotter and single tone rather than dual.
12) Can staff disable a Detex EAX-500 without a key?
No, and that is the point of the cylinder version. Silencing requires the proper control key, and the housing is built to resist tampering or being disabled by hand. For a stockroom or a fire exit that employees keep propping, that key-only silencing is what stops the alarm from being defeated between rounds.
13) Difference between the Detex EAX-500 and the Alarm Lock 700 and 710 Sirenlock units?
The Alarm Lock 700 Series and 710 Series Sirenlock units are 36 inch exit alarms with a 95dB dual tone siren, the 710 described as a commercial exit control alarm system. The Detex EAX-500 is a self-contained battery powered unit with a 100dB piezo horn, a cylinder lock for key silencing, and a tapered cover redesigned to fit narrow stile doors. If the door is a narrow stile aluminum storefront leaf, the EAX-500 cover profile is the reason to look at it first.
14) We are standardizing exit alarms across a hospital. Which unit keys alike across many doors?
The Detex EAX-500 is ordered keyed alike so one control key silences every unit in the group, or keyed different where each door is to be held separately, in black or gray and with or without the weatherized build for exterior openings. It is a commercial rated unit and the alarm can only be silenced with the proper control key, which is what keeps staff from disabling a door. Among the alternatives, the Alarm Lock 710 Sirenlock is the commercial exit control alarm system in that group.
15) How do I know a Detex EAX-500 is armed before I walk away from the door?
The unit gives both an LED visual and an audible arming indicator, so a maintenance tech or guard doing rounds can confirm the state at the door without a key or a panel. Combined with the low battery alert, that is the whole status feedback you get; there is no remote annunciation from the unit itself.
16) Is the Detex EAX-500 rated for commercial use or is it a residential alarm?
Commercial. Detex builds the EAX-500 for commercial exit control, and it is specified into retail loss prevention, healthcare access control, schools, industrial plants, and government buildings. It is not a homeowner door chime.
17) What finishes does the Detex EAX-500 exit alarm come in?
Black and gray, and both are offered keyed alike or keyed different and in standard or weatherized form. Gray tends to disappear against a painted hollow metal frame; black reads better on dark anodized aluminum storefront.
18) Where do I get the mounting template and wiring detail for a Detex EAX-500 install?
Detex publishes full installation instructions for the EAX-500, and ZenSupply carries both those instructions and the catalog page on the product record. Detex also has short install videos covering the mortise cylinder version, the magnetic switch version, and the arming and re-handing sequences, which are worth watching before the first one goes up.
