4 Installaon

ATTENTION: This equipment contains components that can be damaged by

electrostac discharge. Ensure both you and the equipment are earthed before

beginning any servicing.

The Gallagher T20 Terminal can be mounted on:

• a vercal, rectangular 50 mm x 75 mm (2 in x 3 in) ush box

• a BS 4662 Brish Standard square ush box

• a Gallagher Mounng Block (C300930 or C300931)

• any solid at surface

The recommended mounng height for the terminal is 1.1 m (3.6 ) from the oor level to the centre

of the terminal. However this may vary in some countries and you should check local regulaons for

variaons to this height.

Notes:

• Consideraon should be given to the installaon environment when using Gallagher mobile

credenals, as the Bluetooth® wireless technology read range may be reduced.

• Installaon on metal surfaces, parcularly those with a large surface area will reduce read range.

The extent to which the range is reduced will depend upon the type of metal surface. A spacer

(C300306 or C300307) can be used to help migate this issue.

• A black dress plate (C300323) can be used to cover previously installed terminals ensuring a clean

nish for sites handling an upgrade.

• When mounng on a ush box, the corner screws must be used as well as the ush box screws.

Without corner screws the top of the product is vulnerable to separaon from the wall.
