Help! Door entry system buzzer no longer working

[DrJarmin]

All, my communal door entry system no longer buzzes but the button to release the door still works. Popped it open and the wiring appears intact. Any advice on any troubleshooting steps? I’m guessing this system is around 15-20 years old. No clue how to obtain a replacement part.

Thanks !!

There’s no buzzer it’s tone generated ….it’s either ….bad contact on button on outside panel / broken wire for call …..or do you have external sound on handset ? If not check the speaker ( 45ohm) in the handset . That would be a starting point

hi @sparkymarka , there is no external sound on the handset. So in this unit does the handset speaker emit a tone in place of a buzzer?

 

[sparkymarka]

Yes it comes out of the handset speaker , looks like it’s ensign council system , these may not connect the speech path untill the handset is called , do the leds for privacy work ? Has the handset been off the wall ? As it’s probably fuse protected

 

[DrJarmin]

Thanks. That makes sense. Yes, it is in a council flat and was off the wall briefly for the conduit holding the cable to be chased into the wall. Is Ensign a brand ? Only logo i can find is a sort of lower case letter “b”. Where is the fuse ?

 

[sparkymarka]

Google intercoms r us , handset finder it will give some information , it’s a modified bitron video handset , there will be a control cabinet somewhere …

 

[DrJarmin]

Wow thanks. Very informative. I’m guessing I wouldn’t have access to the control cabinet as it’s in a block of flats but I’ll try and ask the council.

I forgot to reply the privacy LED never has seemed to work. The red LED flashes when someone opens the door after pressing the release button.

Given this unit is discontinued are replacements available ?

 

[sparkymarka]

Go onto intercoms r us ….handset finder , scroll down to this handset and below it is the replacement unit …..was any of the wires removed when it was taken off the wall ? have they been put back in the correct terminals ? All way take a photo before removing any wires , I tend to snip them off and leave a small piece of the existing wire in the handset , this also can prevent the fuse getting blown aswell

 

[DrJarmin]

Ok found that. Thanks. Useful tip re wire snipping. Thanks I’ll remember that.

No, no wires were removed or cut. Just had it stored tied up above the door whilst it was chased.

Disconnected the handset. Gave the connectors a clean and plugged it back in. Didn’t work first attempt but oddly 30 mins later it did

If cradle is not down correctly due to back plate being distorted ( overtight and twisting back plate ) it can cause issues , had it myself on some upgrades when wall not even …
