Phone Line Detection solutions to meet ASME Communication Failure Code requirements
The code states that each elevator phone needs to check for an active phone line at least once in a 24-hour period.
The 2100-ALARM and Alarm/Junction Board solution checks the complete phone line system from
the elevators to the machine room and from the machine room to the outside world.
If an active phone line is not detected, it activates an audible and visual alarm at the main landing panel.
