The PBX or other Multi-Line telephone system should now be programmed to
TRANSFER the DOOR PHONE call to the desired destination (‘HOT DIAL’)
once an OFF HOOK condition is detected on the extension to which the DS5
Controller is connected.
This should be done by a suitably qualified telephone technician that is familiar with
programming your system to ‘HOT DIAL’.
The DS5 Controller will automatically terminate the connection at the end of the call.
See page 17 for further detail.
Please refer to the separate User Guide supplied with your Door Phone, to
