P28 - AI4 door switch alarm input
Normally, alarm input AI4 is used for repeater cover opening alarm
EAL4, which is arranged using a door switch (optional). Because of that,
AI4 and AIC are available also in the P28 connector, to which the door
switch is connected. The location of the connector in the cabinet is shown
in Figure 3-8.
The EAL4 door switch alarm is activated 10-30 seconds after the cover
has been opened.
Two alarm outputs
Both the alarm outputs are 1 pole closing and 1 pole opening relay
outputs insulated from each other.
Maximum ratings, related to ground or any other alarm terminal, are
50VAC/60VDC.
The alarm outputs are defined as follows:
Pin 9-1 AO1-AO8 Closed when operating, otherwise open
Pin 10-2 AO6-AO7 Open when operating, otherwise closed
Pin 11-3 AO2-AO5 Closed at alarm state, otherwise open
