12.1 Purpose & intended use
Alarm devices connected to DVST transmission products are intended to allow
verification and response to remote events.
12.2 Alarm Connections
Alarm connections are made via a 37 pin D type male connector which plugs into the
side panel of the DFT0150.

this number the unit dials stored number TEL1 from the dial menu. The
transmitter will continue calling until a connection is made and the
alarm is acknowledged from the receiver.

By default all contacts are ON, or able to respond to contact closures
