& monitoring signals between the engine controller and remote annunciator. The communication link allows a simple, cost effective system installation at any building site. Up to 20 individual fault conditions are remotely monitored utilizing both visual LED lights & audible alarm annunciation. Lamp test and alarm horn silence front mounted pushbuttons are provided.

Annunciator communication data link. 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 (consult Thomson Technology for further details).
2.2. BATTERY SUPPLY INPUT The EAP 110 can operate on any battery supply from 10 to 30 volts DC. The battery DC negative or common conductor must be grounded to the main generator-set frame ground. The EAP 110 is internally protected by a solid state type fuse that protects it from inadvertent shorts.
EAP 110 ANNUNCIATOR 2.2.2. Wiring from the engine control panel to the annunciator should be two - #14 AWG (2.5mm ) wires. 2.2.3. Under noisy environments (i.e. gas engines with high voltage ignitions, etc.), wiring from battery should be a twisted pair of #14 AWG (2.5mm wires.
2.6. ANNUNCIATOR LOCATION/INSTALLATION The annunciator is to be mounted indoors in a dirt free, dry location away from extreme heat sources on a building wall at a suitable location for operating personnel. The annunciator is to be mounted using four screws. The annunciator must be mounted within 1000 feet wiring distance from the MEC 20/MEC 2 Engine controller using an 8 conductor shielded cable.
Com munication Fail FIGURE #4 Alarm labels on the EAP 110 are removable through slots at the top edge of the Lexan. The alarm labels are grouped in 4 rows of 5 labels each. Alarm Fault circuits labels which are programmable in the MEC 2 or MEC 20 Engine Controller can be relabeled on the EAP 110 Annuciator to correspond accordingly.
