No you cant install a microwave based sensor inside a cage (metal cage) as it will stop the MW working.

Also what do you have currently on this site?

Best way would be to replace the system with a hybrid panel to use the existing sensors then add rf. But you need to consider range construction etc

the accenta and optima mini are limited in physical size So battery choice is limited. You need to check your standby current to ensure it is suitable. The 'mini' panels wew usually used on smaller installs so the standby is usually low but it should be checked on a regular basis with a multimeter Below is as axample of the largest that will fit https://www.securitywarehouse.co.uk/catalog/intruder-alarm-equipment-c-36/intruder-alarm-ancillaries-c-36_46/enersys-12v-23-ah-battery-p-1339.html

Should be taken on service and any works

Yes generally but can you confirm which model you are looking at?

the panel will require a default. This will wipe all programming including codes. Are any codes known?

There are very few panels that small anymore. Eaton is a popular choice with good integration options. HKC has better wireless infrastucture if thats needed.

It's not designed for diy fitment. Nut it's a filter so what was connected to the supply should go through it. Keep on eye on load too

Any wired sounder should be suitable but check the polarity of the tamper return

You can usually change them yourself but it is usual the batteries are replaced every 2 years on the service. Care needs to be taken as you can easily damage them if opened incorrectly. Also you may breach your service agreement
