You will need
1 x 6LR61(PP3) alkaline battery for Extender
2 x LR6(AA) alkaline batteries for Door Chime
We recommend that only longlife alkaline batteries are used. This product will not work with NiCd rechargeable batteries
A small flathead screwdriver
A Philips crosshead screwdriver

Please note : The extender is not suitable for outdoor installation. We recommend you read the Vital Information about system codes before installation.
Positioning the Extender or Door Chime on or near metal structures or reinforced PVCµ doors or door frames may reduce the transmission range.

Open the Extender cover using a flathead screwdriver, Diagram 1,and remove the screws. Decide on the location of the Extender and on the length of cable you will require. Feed the cable through the cable inlet (A in Diagram 4). Attach the Extender to the wall using the screws provided, Diagram 8. Then follow one of the
two installation options below.
Option 1. Installing the Extender for use with an existing Wired Bell Push and Door Chime.
Disconnect the power supply to your existing Chime by isolating the mains supply (if transformer-powered) or removing the batteries. Connect the Extender terminals in either of the 3 positions X ,Y or Z as shown in Diagram 2, using terminals 0 and 2.
Option 2. Installing the Extender for use with a traditional wired Bell Push, when no wired Chime exists (Diagram 3).
If you are using the extender to allow you to have a traditional decorative bell push on your door, connect the Extender to your traditional wired Bell Push using terminals 0 and 1. See Diagram 3.
To complete your installation, fit the 6LR61(PP3) battery as shown in Diagram 4 and replace the Extender cover securely.
Please note : The Extender always requires a 6LR61(PP3) battery. Always check that the wires are connected to the correct terminals before reconnecting the power or
replacing the Chime batteries.


Remove the battery compartment cover and insert the two LR6(AA) alkaline batteries as shown in Diagram 5.
When these batteries need replacing, the Battery Low Warning Light (B in Diagram 6) will flash every 5 seconds.
The Door Chime can be free standing or wall mounted using the wall bracket provided.
If wall mounting is preferred, screw the bracket to the wall, Diagram 7. The Door Chime hooks onto the wall bracket as illustrated.
There is an external adapter socket (C in Diagram 6) which allows you to power the Door Chime receiver from a 220-240V mains socket using the Friedland Libra plug-in mains adapter which can be purchased separately (D254).

Tune Selection
Your Extender can be set up to make the Door Chime play a 2 note or 4 note sequence.
The Tune Selector in the Extender (D in Diagram 8) is factory set to position 1 making the Door Chime play the standard 2 note sequence. If you would prefer the 4 note sequence just move Tune Selector to position 2.
You can change the note sequence at any time by using the procedure above.

Volume Control
The Volume Control (E in Diagram 6) enables you to adjust the volume of your
Door Chime at any time or turn it off completely. As shown the settings are:
2. High
1. Low
0. Mute
