apologies its the 507n that is the tone generator which isnt listed on your site. the videx wiring diagram connects the no 4 wire for the 3 seperate handsets through the relay 506 to the 507 and that is connected to the 520 power supply. persumably the call tone activates the relay which activates the call tone via the power supply which is conducted to the other 3 handsets.

can you give me the dimensions for the above lock? Is the .9 amp a peak current as il be using the 1 amp elmdene supply? Also is it designed for recessing like normal solenoid locks (ie not a magnetic lock which is bulky) I want to recess it into door frame directly above door centre.

What happens when more than 3 videx handsets are used on a videx system without a booster? Is there any chance of damage. Im ordering the handsets with slide mute so persumably it disables that handset while allowing others to function. I will at most need 3 handsets at any one time. I have a videx diagram that uses 506n tone generator but you dont list it on your site. Thanks again

Out of interest can one use the bpt call booster for this or does videx do an amp?
