1. Introduction
The DCA1/DCA2 Door Entry System enhances entry security by enabling the user
to recognise the potential entrant by audible means before opening the door.
An electric door catch (not supplied) is available as an optional extra for the
DCA1/DCA2 to make the door opening automatic.
The DCA2 external intercom has the ability to call separately located internal
intercoms for two individual dwellings with a common entrance.
The DCA1 calls one.
Connecting cables between component parts are all 2 core, so existing bell fl ex
can be used to connect the internal and external units if desired.
2. Overview
If operation with an electric door catch is required then part DCLR is a fail
(power off) secure catch available from Timeguard.
