Detex 105828-1 – Frequently Asked Questions

1) Will the Detex 105828-1 circuit board work in an EAX-500 or other Detex exit alarm?
No. The 105828-1 board is built for the Detex EAX-300 Series exit alarm devices only. It is not a universal alarm board, so if your unit is anything other than an EAX-300 Series, this is the wrong part and you need the board specified for that model.
2) My EAX-300 exit alarm has stopped sounding. Can I repair it instead of replacing the whole unit?
Board-level repair is the point of the 105828-1. It restores the electronic function of an EAX-300 Series exit alarm, so a facilities team can service the existing device on the door instead of pulling and replacing the complete unit. The mechanical hardware and mounting stay in place.
3) Is the Detex 105828-1 a genuine Detex part or an aftermarket board?
It's a genuine OEM Detex component, sourced from Detex and built to original factory specifications for the EAX-300 Series. That matters for a maintenance department standardizing on Detex hardware: the board drops into the compatible unit without modification, so the alarm goes back to its designed performance rather than an approximated one.
4) What do I order the Detex 105828-1 by, and are there options to specify?
One part number covers it: Detex 105828-1. There's no handing, finish, or voltage choice to pick on this board, so the only thing to confirm before ordering is that the device on the door is an EAX-300 Series.
5) Is the Detex 105828-1 board rated for commercial door use or is it a light-duty part?
Commercial. The 105828-1 is catalogued as a commercial-grade exit device part, intended for the traffic and duty cycle of schools, hospitals, warehouses, retail and government buildings running EAX-300 Series alarms on exit doors. It is not a residential-grade component.
6) Who typically installs a replacement circuit board in a Detex exit alarm?
In-house maintenance staff, door hardware technicians, and security system installers all handle this one. The 105828-1 is purpose-built for the EAX-300 Series platform and seats directly in the unit, so it's a swap rather than a rebuild, though the person doing it should be comfortable working inside a powered alarm device.
