4 Diagnostics

4.1 Self-diagnostics

The EC-Phone continuously monitors its own operation and its environment and will
report on its alarm status through the programming mode (locally or remotely) or if the
<ALARM STATUS> button is pressed
 Normal
 Line in use
 No main power
 Phone line fault
 No emergency response (call centre no answer)
 No battery
 Low battery
 Charging battery
 Dead battery.
Advance notice of a non-functioning phone gives building managers and owners the
opportunity to repair the fault, increasing safety and reducing liability.
Nine LEDs provide the essential information at a glance:
1. Alarm (off; flashing red = no power; solid red = other alarms)
2. Heartbeat behind the keypad (pulsing green)
3. Power (green)
4. PLM (green)
5. Keypad awake (green)
6. Program mode (green)
7. Line Test call in progress (green)
8. Emergency call status on car panel (solid red = connecting; flashing red = 2-way
voice)
nd
9. Optional 2 LED on car panel (available for customized indication)

4.2 PLM (Phone Line Monitoring)

The Phone Line Monitoring (PLM) feature monitors the phone line as required by ASME
A17.1/CSA B44 Code to generate an audible & visual alert in the elevator lobby. If a
Consolidator or Rescue Station is installed the EC-Phone checks the line from the cab
to the Consolidator. A pair of contacts is built-in, which will open on alarm (fail-safe).
A PLM test feature is available to simulate an alarm for the number of seconds entered,
after which it returns to normal.
