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.

Input circuits: minimum working/service voltage: 12 volts Output circuits (switching DC): minimum working/service voltage: 30 volts Reader data lines: minimum working/service voltage: 5 volts Reader power: minimum working/service voltage: as required by reader RS-232 communication: minimum working/service voltage: ±25 volts RS-485 communication: minimum working/service voltage: ±7 volts Ethernet (non PoE): minimum working/service voltage: 5 volts PoE: minimum working/service voltage: 60 volts

Mercury supports up to 128 floors.

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 Mitsubishi

On the EP series controller the minimum password length is 6 characters. The maximum password length is 10 characters. On the LP series controllers this has been changed to be between 8 - 64 characters.
