2.7.16 Alarm Output Connections
(User Wired in Controller Box or Junction Box)
There are two different alarm outputs. The first is a
general alarm (fused @ 1.0 amp) that is initiated by any
of the alarms described in Section 4.11.
The second alarm output is a float switch alarm that is only used with 3D TRASAR models that are
fully enclosed. This alarm is initiated if water starts accumulating in the enclosure. This alarm
should be sent to a location where it can be responded to as quickly as possible to avoid damaging
the electronics.
