The ET98A Line Loss Indicator is an interface between the elevator phones and the lobby panel.
Wiring:
1. Bring signal wires from elevator phone to left-hand side of ET98A. Wires must be 16 - 20 gauge and are not polarity specific.
(Remove and save jumpers as needed.)
2. Only one Line Loss signal wire pair from a single phone can be connected to each Line terminal. To enable line loss detection for
each LINE# terminal used, remove the corresponding jumper. Note: the jumper for LINE#1 is intentionally missing since by
default at least one LINE is used. For single phone applications, please only use LINE#1.
3. Bring wires from ET98A output to Lobby panel. These are polarity sensitive. Positive (+), negative (-).
4. Mount the ET98-DB in the lobby panel.
5. Wire as shown in diagram (Observe polarity for Power, LED, and Buzzer.)
6. Plug in power cube to board and 110v outlet. Plug in battery backup.
Testing The ET98A:
1. With all phones hooked up and good phone lines, all LEDs should be green.
2. Remove the line loss connector from one phone, and the corresponding red light should begin flashing.
3. The buzzer should start sounding at 30 second intervals.
4. Flip the Buzzer switch (if equipped) in order to silence the buzzer; the LED should continue to flash.
5. Hook the line loss connector back to the phone, and the LED will stop flashing.
6. Repeat as necessary for the other phones.
Testing the phone:
1. Remove the phone line, AC power, and battery power.
2. Reconnect the AC power and battery. (It will say “Sure Phone power installed.”)
3. This starts a timer and will cause a fault at five minutes with no phone line connected.
4. To reset the unit, reconnect the phone line and do a test call.
Note: A quick test can be performed by disconnecting the phone line and attempting to make a call. The LED and Buzzer will activate momentarily.
