SYSTEM INTRODUCTION

This kit will enable a caller at an entrance point to signal an occupant in the dwelling by
pressing a call button which will send an electronic call tone to an audio telephone. A
Yellow ‘SPEAK’ LED will indicate the call has been answered and a two way conversation
can take place, the occupant can release an electric lock release by pressing a button on
the telephone base unit. The kit does not include the electric lock release. A 12V AC
release should be used with this kit (The output for the lock is a dry contact relay so any
other type of lock can be used with an appropriate PSU). If this kit is to be used with a
gate, the dry contact output can be used to trigger the gate control board. DDA features
such as a ‘SPEAK’ LED, ‘DOOR OPEN’ LED and reassurance tones are standard on this
kit.
A two code, two relay codelock unit is also incorporated into the door panel to allow users
to gain access using an access code.

PSU. Up to a maximum of three telephones can be used on the system to call in parallel.
