DESCRIPTION
If you are using an ordinary single telephone line, you will notice that your
telephones WILL RING DIFFERENTLY, to alert you that the call is from your Door
Phone.
If you are using a Cordless Phone or a PBX telephone line, your telephones MAY
NOT RING DIFFERENTLY, as a small number of these devices can ignore our
ring and output there own ring.
DS1 can be used with MOST CORDLESS PHONE MODELS. However, a small
number of CORDLESS PHONE MODELS may ignore the ring from DS1 and will
NOT RING when there is a Door Phone call.
If you have a CORDLESS PHONE that will not ring, it will be necessary to also use
one or more CORDED TELEPHONES on your line (or a Ringing Bell Accessory
that is available from most retail outlets that sell telephones).
CORDED TELEPHONES will ALWAYS RING, and will alert users of CORDLESS
PHONES that do not ring that there is an incoming Door Phone call. You can still
ANSWER, COMMUNICATE and CONTROL LOCKS with CORDLESS PHONES
that do not ring.
Alternative Controllers are available which provide the following features:
DS1 - PSTN connection, no lock control.
DS2 - PSTN connection, single lock control & call advice facility
DS3 - PSTN connection, dual lock control, with Dial Out facility
DS4 - For PBX Extension or FXS/ATA connection, no lock control
DS5 - For PBX Extension or FXS/ATA connection, single lock control
DS6 - PBX Extension or FXS/ATA connection, dual lock control, with dial out
DS7 - As per DS2 - works with telephone instead of Door Phone.
DS8 - As per DS5 - works with telephone instead of Door Phone.
DS9 - As per DS3 - works with telephone instead of Door Phone.
