1.2. GENERAL DESCRIPTION
The EAP 110 annunciator is designed for remote fault annunciation of emergency
standby generator sets utilizing Thomson Technology MEC 2 & MEC 20 Engine
Controllers. The design uses an 8 conductor RS 422 communication data link to
provide the control & 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. Each fault is individually programmable for
audible horn operation and alarm labels are field configurable. Operation logic includes
a “auto-ringback” feature to annunciate subsequent alarm conditions. For applications

EAP 110 ANNUNCIATOR
requiring additional alarm annunciation from remote sensing contacts, the EAP 110 can
accept up to 4 hard wired contact inputs dependant upon the alarm configuration,
separate from the 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). 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.

contents subject to damage by
STATIC ELECTRICITY
This equipment contains static-sensitive parts. Please observe the following anti-static
precautions at all times when handling this equipment. Failure to observe these
precautions may cause equipment failure and/or damage.
• Discharge body static charge
before handling the equipment (contact a
grounded surface and maintain contact while handling the equipment, a
grounded wrist strap can/should also be utilized).
• Do not touch any components on the printed circuit board with your hands
or any other conductive equipment.
• Do not place the equipment on or near materials such as Styrofoam,
plastic and vinyl. Place the equipment on grounded surfaces and only
use an anti-static bag for transporting the equipment.

2. INSTALLATION
2.1. GENERAL INFORMATION
The following installation guidelines are provided for general information only
pertaining to typical site installations. For specific site installation information,
consult Thomson Technology as required.
EAP 110 ANNUNCIATOR
NOTE:
Installations should be done according to all
applicable electrical regulation codes as
required.
CAUTION!!!
All installation and/or service work performed must be done by qualified
personnel only. Failure to do so may cause personal injury or death.
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. The solid state fuse will
automatically reset when the overcurrent condition is removed. Wiring from the
engine cranking battery to the annunciator should conform to the following
guidelines to avoid possible malfunction and/or damage.
2.2.1. Avoid wiring from the engine starter terminals - wiring should go
from the engine control panel.
directly
CAUTION!!!
The battery charger must be turned off before battery cables are
removed from the battery (i.e. for servicing). Failure to do so may
subject the annunciator to an overvoltage condition in which
damage may result.

EAP 110 ANNUNCIATOR
2.2.2. Wiring from the engine control panel to the annunciator should be two #14 AWG (2.5mm
2
) 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.
2.3. EXTERNAL CONTACT INPUTS
All external contact inputs to the EAP 110 are optically isolated and filtered for
protection from noise spikes and transients. Wiring should conform to the
following guidelines to avoid possible Annunciator malfunction and/or damage
2.3.1. External contact wires (2 - #14 AWG (2.5mm
separate conduit.
2.3.2. Avoid wiring near AC power cables to prevent pick-up of induced
voltages.
2.3.3. An interposing relay may be required if field wiring distance is excessively

) should be run in a
2
)
long (i.e. greater than 100 feet (30m) and/or if a remote contact has a
resistance of greater than 5.0 ohms.
2.3.4. The external contacts (if used) must be voltage free (i.e. dry contact).
The use of a “powered” contact will damage the Annunciator.
2.4. REMOTE COMMUNICATION WIRING
All interconnecting wiring to/from the EAP 110 Annunciator communication port
shall utilize #22 AWG (min.) 8 conductor, twisted, shielded cable with RJ45
connectors. The drain (shield) wire must be connected at the Engine Controller
end only. Refer to connection diagram in Section 7 for further information.
Communication cable from the Annunciators’ com port must be suitably routed to
protect it from sources of electrical interference. Guidelines for protection against
possible electrical interference are as follows:
• Use high quality, 8 conductor shielded cable only with drain wire
grounded at the Engine Controller end only.
• Route the communication cable at least 3 M (10”) away from sources of
electrical noise such as variable speed motor drives, high voltage power
conductors, UPS systems, transformers, rectifiers etc.
• Use separate, dedicated conduit runs for all communication cables. Do
not tightly bundle communication cables together in the conduit. Conduit
PM058 Rev 2 06/01/18 Thomson Technology

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.
For additional information on protection against electrical interference, contact
Thomson Technology factory.
2.5. 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)
2.5.1. Battery Control Power #14 AWG (2.5mm
2.5.2. External Fault Contacts #16 AWG (1.5mm
2.5.3. Remote Communication Wiring #22 AWG (0.34mm

For distances exceeding 1000 Ft. (300m) consult THOMSON TECHNOLOGY.
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. 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.
