[Replacement PIRs for Optima XM]

No problem with pets... I've seen that some have a pet version.. However I just put the cats out when we're out!

 

Funny story..  One Christmas we hung a large decorative  star from the hall ceiling.   you can guess what our  neighbours phoned to tell us later that day...... lol.

 

 

On topic.. I looked at the dataset for the Bosch blueline and in the spec it states

 

Relay: Solid state, supervised, Form A normally-closed (NC)
contacts rated for ≤100 mA, 25 VDC, 2.5 W, <20 Ω
closed

I thought Form A was the descriptor for a normally open contact?

 

 

 

 

[Replacement PIRs for Optima XM]

I have an Optima XM alarm system with 4 PIRs around the house.  As I'm decorating I'd like to replace the PIRs as the plastic housings have discoloured over the years.

 

Can anyone advise a suitable PIRs for this panel?

 

Thanks in advance.
