The Hotline 4 unit provides a method of connecting up to four remote telephones back to a single reception/host telephone with instant calling being created by lifting the telephone off-hook.
Lamps and keys are provided on the base unit to allow calling to the remote telephones and also indicate the remote telephone status.
An optional ALL CALLS button can be provided on the unit to ring all extensions with an alternative ring cadence for emergency use.
Unit is powered via an external in-line or plug top PSU.
All remote telephones are terminated via a single RJ45 connector with each 2W telephone presented on each pair colour.
