Line Monitoring Alert Panel Meets Elevator Codes

The Line Monitoring Alert (LMA) Panel from Janus Elevator Products meets ASME/B44 2009 and 2010 code requirements for elevator phone line status notification. The unit provides audible and visual signals in the building lobby in the event of phone line failure. When used with Janus EMS phones featuring the phone line monitoring option, the LMA unit completes the warning system. To manage multiple phone lines, the LMA can be used in conjunction with Janus' Line Monitoring Expansion (LMX) unit. Mounted in the machine room, adding the LMX allows up to 10 elevator phones to be connected to the LMA panel.

The LMA panel can operate as a standalone unit or be incorporated into a lobby panel. One pair of wires from either the elevator phone or LMX and 110 AC power are required for installation. Onboard volume control adjusts the audible signal, with a reset function to silence it using a standard J200 key. The unit resets automatically when the phone line is restored. A test feature enables manual system checks.
