Programming Multiple Units Overview
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.
Up to seven (7) EL25s can be installed on a single telephone line.
Each
unit must have a “
Unique
Unit ID”
number and the
“Number of Units in Chain”
assigned to it.
If you make an error during an entry, press the asterisk key (

2 Unit ID Number (1-7), Then
3 Total Number of Units in Chain (1-7), Then
The unit ID identifies each unit within a chain. Adding or removing EL25s will require the unit ID's to be re-entered.
Factory Setting: Unit ID 1 and Number of Units in Chain 1.
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.
