  1. Replacement PIRs for Optima XM

    strinjf replied to strinjf's topic in !!..DIY Installers..!!
    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?

  2. 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. John.
