Title: Siemens wire free door chime
Post by young senior on Apr 19^th, 2012, 3:02pm

On reading installation instructions: item 2 reads, avoid mounting bell push on UPVC door frame, bell push should not be mounted on UPVC door frame as operating range will be reduced. Didn`t know about this limitation until opened packaging.
If I insulate bell push with plastic or wood fillet when fixing to door frame would this eliminate or reduce possible loss of operating range ie signal strength.
Advice please

I would guess they state this due to the metal skeleton that will be inside the door frame.

All uPVC doors have a metal skeleton (ones that don't are horribly cheap and you can feel this when you open/close them).

uPVC windows generally do not until you go up to larger non-standard sizes of opening.

Obviously metal will reduce the range of the transmitted signal from the bell push.

Try it with the bell push held to the fram with tape before you drill any holes. Might work if the reciever unit is just going indoors by the door.

I used a Byron wireless door bell because I was concerned the metal foil covered insulation in my walls would cause problems with the signal. Our mobile signal is certainly affected.

The set up I have uses an ordinary wired push button on the outside with a short wire through the wall to one of these "wired push converter" on the inside. Basically it's one of their wireless door pushes without a button on it....

That can be used with any of their SX series of receivers/bell boxes. We opted for a battery powered unit that and can be moved around the house. They also have mains plug in units.

There is one real time example on this free door chime is I have just been given the job to install a doorbell for my girlfriends mum. The problem is she has a PVC door frame where she wants the doorbell mounted. Can I drill and fix a door bell in place on the doorframe? Also can I drill through the frame at different levels and fish the cable down the frame?Sorry its hard to explain. Any help will be appreciated, thanks guys.

You might have real problems fishing for the cable. Why not use a cordless bell?

Mine is located on my PVC door and the receiver is two rooms away and I have no problem.

Spoke to tech guy at Siemens UK .
Sometimes operating range not affected when mounting bell push to UPVC frame, however cannot be sure until you trial mount bell push with say blue tack to find out extent of problem.
To overcome this, installation kit will soon include a 10mm spacer to fit between frame and bell push, this should eliminate operating loss.
Thanks for posts
