17 Off-Hook Detection
The EVCS has enhanced features to detect off-hook handsets and jammed buttons at outstations.
Off-hook detection (at Type A outstations):
Scenario: A call has been made from a Type A outstation,
the call has been answered and ended at a control unit but the handset at the outstation has been left off-
hook for longer than 2 minutes.
Jammed button detection (at Type B outstations):
Scenario: A call has been made from a Type B
outstation, the call has been answered and ended at a control unit but the button at the outstation has
pressed / jammed for longer than 2 minutes.
For the two scenarios above, after the 2 minutes have elapsed, the fault buzzer at the control unit sounds, the Fault
indicator lights and a fault message is displayed, see example below left. Press
CALL/ACCEPT
button at the control
unit and details of the off-hook or jammed button extension is displayed, see example below right.
To rectify the fault either,
1. Call the extension from the control unit to check if someone is still waiting at the outstation for an answer,
or,
2. Go to the extension and replace the handset at Type A outstations, or release the jammed button at Type
B outstations.
