Protect exterior emergency exits, gates, and restricted openings with the Detex EAX-500W Weatherized Exit Alarm.

Designed specifically for outdoor and wet environments, the EAX-500W provides a powerful 100 dB audible alarm whenever an unauthorized exit occurs. Its self-contained 9V battery operation eliminates the need for a dedicated power supply, while the rugged, tamper-resistant weatherized housing is built for demanding commercial applications.

The compact tapered design also allows installation on narrow-stile doors, making the EAX-500W an excellent choice for storefronts, warehouses, loading areas, gates, and exterior emergency exits.

100 dB Exit Alarm

When the EAX-500W is armed and the protected door or gate is opened, the built-in piezo horn sounds at approximately 100 dB, immediately alerting employees, security personnel, or nearby occupants to unauthorized use of the opening.

The alarm can only be silenced using the proper control key, helping prevent unauthorized users from defeating the alarm after activation.

Built for Outdoor Environments

Unlike standard indoor door alarms, the EAX-500W is specifically weatherized for exterior and wet applications.

Its protected electronics are designed for demanding environmental conditions and have been certified to applicable:

• Driving rain testing

• Salt fog testing

This makes the EAX-500W ideal for openings exposed to moisture, humidity, and changing outdoor conditions.

9V Battery Operation

The EAX-500W operates from a standard 9VDC battery, allowing installation without running a dedicated electrical power circuit to the opening.

A built-in low-battery warning helps alert maintenance personnel when battery replacement is required.

Automatic Door Handing

The EAX-500W features intelligent circuitry that senses the position of the external magnet and automatically establishes the proper door handing.

This simplifies installation and reduces setup time when compared with alarms requiring manual handing adjustments.

Extended Bypass

The standard extended-bypass feature allows authorized personnel to bypass the alarm while the door remains open.

Once the door closes, the EAX-500W automatically returns to its armed condition, helping prevent the opening from accidentally being left unprotected.

Selectable Auto-Rearm

Installers can select a 2-minute automatic rearm mode when desired.

This allows the alarm to sound following unauthorized operation and then automatically return to its armed condition without requiring manual reset for every activation.
