EAP 110 ANNUNCIATOR
should be ferromagnetic type near sources of possible electrical
interference. The entire length of conduit should be grounded to building
earth ground.
•
When communication cables must cross over low or high voltage AC
power conductors, the communication cables must cross at right angles
and not in parallel with the conductors.

ANNUNCIATOR CONTROL WIRING
As a minimum, all control wiring shall conform to the local regulatory authority on
electrical installations. Specific wire sizes for typical circuits (of distances up to
1000ft (300m)
Ê
) are as follows:
2.5.1. Battery Control Power
#14 AWG (2.5mm
2
)
2.5.2. External Fault Contacts
#16 AWG (1.5mm
2
)
2.5.3. Remote Communication Wiring
#22 AWG (0.34mm
2
)
8 Conductor Shielded Cable

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. The standard annunciator is suitable for surface mounting as
shown in FIGURE #1. The annunciator is available with an optional adapter plate for
flush mounting application as shown in FIGURE #2. Assembly details for the flush
mounting adapter are shown in FIGURE #3.
