Multiple Entrances
The bell issimo system allows multiple entrances to be catered for by the addition of a door
controller and entrance panel for each entrance and additional power supplies.
Gate and Block Systems
Sites with two or more blocks sharing one or more site entrances are catered for with our
BSSW Gate controller. The blocks can then work independently but will receive calls from
the shared entrance.
For further details see the “bell
issimo and Bellcall Manual Gate and Block (PD-
120)”.
Door Bell
The BS Videophone has an input which can be used with a doorbell button (or other volt
free contact) to ring the phone. This feature is intended to replace a separate doorbell.
The ring is 2 seconds and all three indicators flash together.
Slave Output
The BS Videophone has a slave output which can operate an external ringer or other
device such as a flashing beacon.
This comprises of a volt-free contact which closes when the videophone is audibly ringing.
The contact does not close when the videophone is muted.
