Tech Tip

The Detex Electric Latch Retraction (ER) device requires 1.5 amps to retract the latch. In order to power a Detex Electric Latch Retraction device, a power supply must provide a filtered and regulated voltage of at least 24VDC and no more than 28VDC. Detex recommends using a Detex power supply to power the device. 


However, if an alternative power supply is desired, it must be filtered and regulated and have at least 2 amps for each exit device being powered. Alternative power supplies should be preapproved by Detex.


Powering Detex latch retraction exit devices with other power supplies described above will not void the manufactures warranty. However, failure to power Detex exit devices properly can void the warranty. Warranty replacement is determined by Detex following inspection of the exit devices and power supply.
