3E4290 Gallagher T12 Reader | Edion 1 | August 2016

** Recommended cable types for opmal HBUS RS485 performance.

*** Not applicable for Gallagher mobile credenal reader installaons.

Notes:

• Shielded cable may reduce the obtainable cable length. Shielded cable should be

grounded at the Controller end only.

• If other cable types are used, operang distances and performance may be reduced

depending on the cable quality.

• HBUS allows up to 20 readers to be connected to a single cable. Each reader requires at

least 9 Vdc to funcon correctly. The cable length and the number of readers connected

will have an impact on the voltage at each reader.

3 Distancebetweenreaders

The distance separang any two proximity readers must not be less than 200 mm (8 in) in all direcons.

When mounng a proximity reader on an internal wall, check that any reader xed to the other side of

the wall is not less than 200 mm (8 in) away.

200 mm

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 T12 Reader is designed to be mounted on a standard Brish electrical ush box, or any

solid at surface. However 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.

Note: 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.

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

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

variaons to this height.

1. Ensure the building cable has been run out through the ush box.

If you are not mounng to a ush box, use the reader bezel as a guide to drill all ve holes. Drill

the 13 mm (1/2 inch) diameter centre hole (this is the centre hole for which the building cable

will exit the mounng surface) and the four xing holes.
