Installation guide

Modular jack: Each voice terminal wiring run from the jack field terminates in a modular

jack at the voice terminal location. Every voice terminal has a separate modular jack.

Voice terminal (MERLIN system telephone): The voice terminal provides basic

telephone functions as well as access to the advanced feature software residing in the

control unit.

MERLIN system voice terminals may be installed in a near-by building by using

Outdoor Wiring Protection Units. Contact your equipment supplier for more information.

Basic Touch-Tone and rotary telephones may also be used as off-premises telephones

with the MERLIN system using the optional Off-Premises Telephone Interface to

connect them. In that case, off-premises telephones access system features by means

of dial codes.

The following pages describe in detail the control units (by model), optional cartridges and
