Detex 105838-1 – Frequently Asked Questions

1) Will the Detex 105838-1 circuit board work in an EAX-500 or EAX-300 alarm, or only the EAX-500W?
The 105838-1 board is specified for the Detex EAX-500W Series only. It is the genuine OEM board for that series and is meant to drop into EAX-500W hardware. Don't order it for a different Detex alarm family expecting a match, since the only series it is documented against is the EAX-500W.
2) My Detex EAX-500W alarm stopped sounding. Can I replace just the board instead of the whole unit?
Yes. The 105838-1 is sold as a board-level repair for the EAX-500W, so a failed or damaged circuit board can be swapped out to bring the alarm back to operating status without buying a complete new unit. That is the point of the part, and it is why facility maintenance groups stock it rather than a spare alarm.
3) Is the Detex 105838-1 a genuine Detex part or an aftermarket board?
Genuine Detex OEM. The 105838-1 is the factory replacement board for the EAX-500W Series, built to the same standard as the one originally installed, which matters if the alarm is part of a documented exit-door setup an inspector looks at.
4) Do I need to order anything else with the Detex 105838-1, like a new alarm housing or cover?
No, the 105838-1 is the circuit board on its own, intended as a direct drop-in into existing EAX-500W hardware. You reuse the housing, cover, and mounting already on the door. If the damage extends past the board, that is a separate part order.
5) What exactly is the Detex 105838-1, a full alarm or just the electronics?
Just the electronics. It is the replacement printed circuit board for the Detex EAX-500W Series exit device alarm, not the complete alarm assembly and not a lock or exit device itself. If you need the whole EAX-500W unit, that is a different order.
6) Is this Detex board rated for commercial use, or is it a residential-grade part?
It's a commercial part. The 105838-1 is classified for commercial applications, which is where the EAX-500W Series is used, including offices, schools, hospitals, retail, warehouses, government buildings, and multi-tenant residential buildings running commercial exit hardware.
