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

PM058 Rev 2 06/01/18 Thomson Technology

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.

CAUTION

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

NOTE:

Installations should be done according to all

applicable electrical regulation codes as

required.

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.

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 directly

from the engine control panel.

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.

PM058 Rev 2 06/01/18 Thomson Technology

EAP 110 ANNUNCIATOR

2.2.2. Wiring from the engine control panel to the annunciator should be two -

#14 AWG (2.5mm2) 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 (2.5mm2)

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 (2.5mm2) should be run in a

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

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)Ê) are as follows:

2.5.1. Battery Control Power #14 AWG (2.5mm2)

2.5.2. External Fault Contacts #16 AWG (1.5mm2)

2.5.3. Remote Communication Wiring #22 AWG (0.34mm2)

8 Conductor Shielded Cable

ÊFor 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.
