Multiple Unit Installations - Linear RE-1 Installation, Programming And Operation Instructions

MULTIPLE UNIT INSTALLATIONS

Any of the four basic operation modes (Shared Line, Dedicated Line,
Intercom, and Ring Down) may be used with multiple RE-1s in the
same installation. The telephone line wiring is "daisy chained" (the
telephone line routes through one unit to the next) as shown below.
Always connect the telephone line + to TIP, and - to RING.
The Telephone Bypass Module only performs the bypass function
in the Shared Line Mode, but it will provide extra electrical surge
protection in all modes. A surge on the TELCO terminals will be
suppressed through the EARTH GROUND terminal. Always use
separate AC transformers to power each RE-1.
When multiple units are connected together, only two units can be
controlled by resident telephone commands, and only one unit
can be programmed to answer the telephone (PPN #33) for remote
telephone commands. Remote programming via computer is not
supported when using multiple RE-1s.

Command Prefi x for Multiple Units
Programming and relay control may be through the individual RE-1
keypads or through the house telephone(s) when using the Shared
Line or Intercom Modes. To support using the house telephone(s)
to issue commands, each RE-1 must be programmed to a different
"command prefi x" (PPN #72).
• Set one unit's command prefi x to
• Set the other unit's command prefi x to
In the case of simultaneous visitors at different units when using
the Shared Line Mode, putting one RE-1 "on hold" to communicate
with the second RE-1, then returning to the fi rst RE-1 is not
recommended. Instead, fi nish all communications with the fi rst RE-1
before servicing the second RE-1. Simultaneous visitors at multiple
units used on a single line wired in the Ring Down Mode will cause
a "conference call" effect between units
