Looking For Replacement Door Entry System

[Hefferl]

I need to replace an existing door entry system.

Only one handset and one call button required.

The current one is a flush panel which mounts into a recessed back box - i'd like to find something that will fit into this back box. The original panel is about 85mm wide and 188mm high, There are two fixings holes @166mm centres. I don't know whether this is a standard size box or not?

The original panel has "Door Security Systems" printed on it.

Any suggestions would be much appreciated thanks.

i have used these in the past https://www.doorentrydirect.com found them very helpful 

you will be lucky to find one the will fit directly into the old back box though ... i would chip out the old one , buy some of this http://www.screwfix.com/p/cementone-general-purpose-mortar-grey-5kg/36857 and install new back box , not a hard job to be honest
