7. EAP 110 REMOTE ANNUNCIATOR OPTION
Optional EAP 110 remote annunciators are available for the MEC 2 engine generator controller.
One annunciator is required for the standard NFPA 110 faults and a second annunciator is
required for additional faults on the controller if required. 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 an 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 contact Thomson Technology to obtain the specific
product documentation available.
