Electric door lock

[Colour Republic]

Ok boys and girls need a bit of help again with a spec.

Here is the background...

Got a client where i'm designing and fitting a number of bathrooms in a refurbed/extended house. One of the bathrooms is more than likely going to end up as a Jack 'n' Jill En-suite (For those unfamiliar, it's where a bathroom can be accessed from 2 different bedrooms i.e 2 doors in to it)

Now normally you'd have to walk into the bathroom, lock your door, then have to lock the other door. And on exit you'd have to remember to unlock both doors again.

To overcome this I thought I could use a power-to-lock bolt. So something like a solenoid bolt would be ideal

CDVI DX200 Fail Safe Solenoid Bolt Lock - CDVI - DX200 Solenoid Bolts - Solenoids & Electric Security Locks - Security Locks - SCS Emporium

Now i've seen these used on things like train toilets, petrol stations, jeweller shops... But i've only seen them with one switch to lock one door. But I would need to lock 2 doors by any one of 3 different switches.

Here's why

A switch would need to be placed nexted to Door A inside the bathroom that when pressed would lock/unlock both Doors A+B

Another switch would need to be placed nexted to Door B, again inside the bathroom that would lock/unlock both Doors A+B

So at this point both switches are inside the bathroom and no way of unlocking the doors from the outside. This en-suite is to be used by the clients 2 kids so we would need to provide a 3rd concealed/hidden switch outside of the bathroom in case of an emergency (Not a toilet emergency you dirty gits! more a kid has banged their head kinda emergency). I know you could cut the power but then a lot of these locks are security locks with battery back-up, so you could have a very long wait.

Soooooo I can't see why any of this isn't possible but i'm wondering if you guys know of decent looking switches that will be up to the job. Also keep in mind the locks are more than likely gonna be 12v. Not sure if these types of lock have a mains powered switch that then steps down to 12v at the lock or if the switches are normally 12v too?


Ideally I'd like to use something like a Varilight touch control dimmer as the switch can be used inside a bathroom (2 gang - one side does the lights, the other the locks) but i've only ever seen these with Master dimmer and then slaves. Clearly the locks won't like the dimmer part.

cheers guys and sorry for the waffle but i was getting it straight in my own head as I typed

Why not put a microswitch in the catch well of each door manual lock. Wire each microswitch in parallel. Each door also has a maglock. If someone goes in and locks the door, the maglock on the other door also engages, all at the same time. That way you don't need to worry about light being on (if the toilet has natural light during the day) or people delaying between turning the light off and exiting.
Of course, where this falls down is if they then want to exit via the other door. Interesting problem tho...

Simple fix, feed 12/24v for maglock through a breakglass in the bathroom on the inside

Well, the other thing that I considered was pressure pads by the doors, so when you stand by the door, it undoes the maglock. but that wouldn't work for a wetroom, and may be too big, plus then the door closes behind you and locks!
Breakglass outside would be a solution, though in my suggestion only one door would unlock.
It's an quirky problem, one we'll have when we re-wire this place as one of the rooms upstairs will have a shared en-suite.
