Shunt locks 

 

Can't find anything about a "graded" shunt lock 

 

We don't fit them, (well I have but donkeys years ago) but have one on a current takeover 

 

Presume this calls up Does this calls up an existing BS4737 standard or something in 50131? I can't seem to see anything about locks though 🤔

 

BS8243 permits a shunt lock for completion of setting -  but wondering where we are in terms of component grade?

 

Many thanks 

If there isn't a standard in the suite then you do indeed use the previous std.

what’s your thoughts on the following?  

 

Existing policed system supposed to be grade 3 (not a chance it is imo) 

 

Anyway,

Area on a wing in a Statley Home is being armed / disarmed by this shunt lock alone 

 

No local sounders - only one entry exit into the area via this door with the shunt fitted. Currently programmed as keyswitch - 5 second exit. Only one Keypad fitted which is in the main body of the house 

 

I’m think this area should have two stage arming - lock programming changed to final - area changed to final set with a local sounder to confirm setting. Keypad then fitted inside the protected area to facilitate disarm on entry - as the lock now programmed as final will disable confirmation on entry 

 

Or, am I over thinking it? 😂

You can 2 stage arm etc but you can also disarm with the shunt lock. 

I'd want a local sounder but notification wise depends on signalling and total sounders
