Can you disarm the system after arming it with the Remote Keyfob, without setting off any sensor by just pressing the 'disarm' button on the Keyfob?

Simple answer is yes. If you press the disarm button before you entry the house (just outside door) then you should be in range to disarm. Alternatively you can set your entrance room PIR (in my case the kitchen) to an 'entry' state, this gives you 30 seconds to disarm the alarm once inside the house.

is this suited to the 6400 kit

works with the Yale HSA6400 Wireless 4-Room Alarm Kit I got from screwfix

Can you disarm the alarm with the keyboard from outside the house when you have a door sensor fitted?

No. The door must be in entry mode (bleeping) before the fob will turn it off. You could use a remote keypad to do it.

does this work with the yale wireless hsa6400 alarm system

Yes it's working fine with mine. Very useful when you use two external doors on a regular basis. Sorry for the delay in answering. (Been away on holiday)
