We have just fitted some Hochiki recessed fire alarm sensors

Hello, I just want to know that which type of alarm sensors are good smoke or a fire alarm sensor.


Note
This is a spammer

If you follow the link to the HA blog then it gives all the information including part numbers.

Looks nice though if it were me I\'d worry, given that they probably have a 10 year lifespan, I\'d have some big holes to plasterboard over in in 10 years time when I cant get the same replacements again to fit in those voids! 

Or are they an industry standard size?

We also fit non Hochiki CO sensors in the same recess base so I think most circular sensors would fit.
