1. Introduction

The DCEX3/DCEX4 Door Entry System enhances entry security by enabling
the user to recognise the visitor by audible and visual means before
opening the door.

An electric door catch (not supplied) is available as an optional extra for the
DCEX3/DCEX4 to make the door opening automatic.

The external and internal intercoms are connected by a two core cable. With
the cable supplied the distance between these units is limited to 15m. By using
13/0.2 bell cable this distance can be increased to a maximum of 70m.

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. See fi g 2 for wiring of this
part. An additional two core cable run (using 13/0.2 bell fl ex) will be required
between internal intercom and door catch.
