1. Introduction
The DCC1/DCC2 Door Entry System enhances entry security by enabling the user
to recognise the visitor by audible and viisual means before openiing the door.
The external intercom incorporates LED lighting to illuminate the visitor for the
camera. This type of lighting has an indefi nte life.
An electric door catch (not supplied) is available as an optional extra for the
DCC1/DCC2 to make the door opening automatic.
The external and internal intercoms are connected by a four core cable. With
the cable supplied the distance between these units is limited to 15m. By using
a larger core diameter cable this distance can be increased to a maximum of
100m, see section 9 (specifi cations) for further details.
2. Product Overview
If operation with an electric door catch is required then part DCLR is a fail
(power off) secure catch available from Timeguard. It requires an additional
mains adaptor part DCADAP to enable operation. See fi g 2 for wiring of these
parts. An additional two core cable run (using 13/0.2 bell fl ex) will be required
between internal intercom and door catch via the additional mains adaptor.
