EAP 110 REMOTE ANNUNCIATOR OPTION
An optional EAP 110 remote annunciator is available for the MEC 20 engine generator
controller. The standard features of the
EAP 110
meet and exceed all requirements of NFPA
110, NFPA 99 & CSA 282-00 building code standards for Emergency Standby Generator
systems. The design uses a 8 conductor RS 422 communication data link to provide the control
& monitoring signals between the engine controller and remote annunciator. Up to 20 individual
fault conditions are remotely monitored utilizing both visual LED lights & audible alarm
annunciation. The
EAP 110
is DC powered from the same 12 or 24V engine starting battery as
the engine controller is connected to. Two
EAP 110
annunciators can be interconnected
together via the communication link to allow up to 40 remote annunciator points from a single
engine controller.
For complete information on the
EAP 110

product documentation available.
