Hi folks
I have a problem with a doorbell, it works fine when the user presses and holds for about a second but if said user presses and releases quickly the action is not registered, I need to find a solution which latches the button momentarily or a button which is slow to release. Added complication is the button needs to be decorative ie not standard doorbell button.....don't ask! Cheers chaps and chapesses ------------------------- Regards Martyn.

Latching relay and 0-6 second timer in a box by the TX ?
Is the circuit voltage "low" - often the cause of the bell not operating on "short" press. regards OMS ------------------------- Failure is always an option |

Sounds unusual that the bell doesn't start to ring immediately (or is there something more to it "registering"?) Might the push button be on its way out - a long press really just being a symptom of a hard press?

The doorbell is part of a security system, the button is a device on a zone and is set to NO the chime is a common function to several actions. I can make it work every time but I need to avoid an instruction leaflet on pressing a button!

The panel isn't set to double-knock or similar on that zone is it?

If you can prove the button good, how about one of of these

@Stu,
That's a good link, all it needs is a RF front end with a small transmitter in the door press housing and the door bell can be positioned anywhere without the need of worrying about volt drop. I'll look at their site in more detail at some point...

If its on a zone then the panel should see it everytime!-maybe a slight delay, but should still do what it's progged to do, also some panels have the facilty to change the 'zone response time', ie the length of time a zone must be active before the panel reacts and treats it as a change of state (Tex premier panels for example).

It sounds like a job for a pin hammer. a little tap here a little tap there to misshape it?
You could consider applying a small blob of strawberry jam bi-annually |

Wireless standard bell going in tomorrow What surprises me about these wireless doorbells is: i) how ugly and bulky the push buttons are ii) you cant hard wire the bell - you are forced to use batteries. These two factors make it no good for my richer clients who i) want it to look half decent ii) don't want to be up ladders changing batteries |

These two factors make it no good for my richer clients who i) want it to look half decent ii) don't want to be up ladders changing batteries Modern push buttons use Mili watts in power consumption and tend to be solid state (10 year life) as for size and design the one I collected today looks identical to a standard door bell button. I'm not going to be short of available permanent 12v supplies trust me! ------------------------- Regards Martyn. Only a mediocre person is always at their best www.electrical contractors uk.com |
