Programming Multiple Units Overview

The unit ID identifies each unit within a chain. Adding or removing EL25s will require the unit ID's to be re-entered.

Verify Unit Number:
This allows you to verify a unit's number within a chain. When you perform this step, the unit will respond with the
number of beeps corresponding to its unit ID number. Two beeps, for example, mean the unit is number 2 in the chain.
Note: You cannot program a unit within a multi-unit chain from a local/remote DTMF phone (Touch-Tone) unless
you know the unit's ID number. Therefore, you can only verify the unit number while programming from the unit's
front keypad.
