So this was a bell module? In the loft? Looks to be in very good condition, do you take down many standard bell modules? like SAB modules? 

 

no its a "scancom" digi unsure of model but dated 1984 ?

 

the trick with bell modules was to leave them in the plastic bag & it stopped most of the rusting

IIRC "Viper foam detector"

 

pcb within plastic case, size of shock sensor

 

IR Led + Receiver below the case

 

Used to FA when the housing filled with webs or bugs ect...

 

Used to FA when it got dark after it had be powered up the 1st time

 

Google has no pics & I've not see one in yrs....

 

Never had a problem with them, used loads in the past

I think we'd about finished with them when I started

 

I recall the sticker s being reprinted to suit the size of cequra with a tel. No with a few digits less than today

Sab1045 bell module I fitted these in the past but can't recall who made them, red/ blk goes to a comfort led

That one looks good, do you still have them? or it? I could try and copy the board design out, im in need of a schematic for one. Excuse my lack of knowledge, but what's a digital? Looks old and interesting.

Just for H 

 

Having a tidy up of the garage and cant believe i found one.

You need a diode across the relay coil of that one you made to protect the transistor and possible a resistor to limit the current the relay pulls, well done on the MK1 cant wait to see your next projects.

 

Send me your address and will send this V foam to you

Wow, thanks. I am glad that you like my projects. I thought about a diode, and I will add one in the Mark 2 version. And thanks again, I will PM you my details.

@MrHappy @Nova-Security Cheers for the help with these, I have finished the Mk. 2 Anti-Foam module, looks very similar to the V-Foam

You could do with a small bit of pipe over the LED and the receiver so it doesnt pick up any stray light
