The HT3011 ReliaBUS™ series intercom system allows
up to 120 HT3011 inside handset stations to communicate
with one or two STR™ modular type door entry stations,
and to release the door opener at each door entry station.
A number of optional accessories are available to provide
a complete entry intercom signaling and communications
system. The HT3011 ReliaBUS™ system requires only
two (2) common 'bus' wires to the remote apt. handsets.
Up to four (4) handsets may be used in parallel in each
apartment/suite (see special notes on page 4).
