The battery on LP series controllers backs up SRAM and the RTC (Real Time Clock). Should a panel have a missing/dead battery and go through an extended power cycle, the onboard configuration will be lost and will require a complete download. Note, on the LP1501 the battery is a rechargeable battery which is only used to backup SRAM as that panel does not have a RTC.

The Mercury products provide both standard elevator control (using relays and inputs) as well as a higher level integration to elevator systems. The standard elevator offering comes in two forms: Type 1: Elevator control without floor select feedback (just using outputs connected to elevator system). Type 2: Elevator control with floor select feedback (uses both outputs and inputs connected to elevator system). The higher level integrations that are currently available are the following: OTIS, Compass, KONE, ThyssenKrupp and Mitsubishi.
