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.

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.

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 (2.5mm

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

4. OPERATING INSTRUCTIONS

4.1. SEQUENCE OF OPERATION

When the EAP 110 is energized and is interconnected to an operating system, it
will display any faults which are currently active on the MEC 2 or MEC 20 Engine
controller. Any new faults will be displayed by a flashing LED light and the
internal alarm horn will sound. Once the alarm has been acknowledged via
“ALARM SILENCE” push-button, the horn will be silenced and the LED light will
remain on continuously. Any subsequent alarms will cause the horn to sound
again and new fault LED to flash. The activated LED lights will remain on until
the fault condition has been reset at the engine controller. If the EAP 110 is also
connected to the 4 possible external contact input circuits, these faults will be
activated in the same sequence by the remote contacts closing or opening upon
a fault. Remote contacts close to initiate an alarm fault.

4.2. CONTROL PUSH-BUTTONS

The following control push-buttons are located on the front faceplate keypad.

4.2.1. ALARM SILENCE FUNCTION

To initiate an alarm (horn) silence function, press the “ALARM SILENCE”
pushbutton. Should subsequent faults be activated, the alarm horn will re­sound which will require another alarm silence action.

4.2.2. LAMP TEST

A lamp test feature is provided to test all LED annuciator lights. To
activate the lamp test feature, press the “LAMP TEST” pushbutton.

PM058 Rev 2 06/01/18 Thomson Technology

EAP 110 ANNUNCIATOR

5. PROGRAMMING INSTRUCTIONS

The EAP 110’s audible horn may be programmed individually per alarm fault
circuit. The EAP 110 will be supplied from the factory with the horn “ENABLED”
for all alarm circuits.

To enter the programming mode, follow the procedure as shown:

NOTE:

The EAP 110 will not provide alarm
annunciation during the program mode.

1. Simultaneously press and hold both ALARM SILENCE & LAMP TEST push­buttons down for 3 seconds, then release.

2. All LED’s illuminated will indicate that they are programmed as the Horn
Disabled. All LED’s which are not illuminated indicate that they are
programmed as the Horn-Enabled. The factory default setting is Horn­Enabled.

3. To program LED D1’s horn function, momentarily press the LAMP TEST
push-button. The flashing rate of the LED will change to reflect the different
settings. The two different flashing rates indicate the following operation:

 Long Pulse On, Short Pulse Off = Horn Disabled
 Short Pulse On, Long Pulse Off = Horn Enabled

4. Once the desired operation is selected for D1, momentarily press the ALARM
SILENCE push-button to advance the programming point to the next LED
and repeat process 3.

5. This process can be completed for all LED lights D2-D22. Once the last LED
is selected (D22), the programming mode will be terminated once the ALARM
SILENCE push-button is momentarily pressed. Note: the programming mode
will be automatically terminated following no key presses in approximately 30
seconds. Once the programming mode is terminated, the EAP 110 will
resume normal operation.

EAP 110 ANNUNCIATOR

9. TROUBLE SHOOTING

A number of problems can cause the EAP 110 Annunciator not to function properly. Refer to
the following list of typical problems. Consult the factory for any detailed information or for any
problems not listed.

CAUTION!!!

Before opening the annunciator to perform any service task, it is imperative to isolate the
control system from any possible source of power. Failure to do so may result in serious
personal injury or death due to electrical shock.

Service procedures must be undertaken by

SYMPTOM CORRECTIVE ACTION

Annunciator does not power up even with correct
DC power applied

Lamp Test does not activate any LED lights on the
EAP Annunciator

DC Power On LED is illuminated and
Communication link is correct however EAP 110
does not respond to any activated fault conditions

qualified personnel only!

- Check that there are no wiring errors/short
circuits connected to the Annunciator. Note:
The EAP 110 contains an electronic fuse that
triggers upon an overload condition and does
not reset until the supply voltage is removed,
and overload condition is corrected.

- Check if adequate DC supply voltage is applied
to the EAP & the polarity is correct.

- Verify the Lexan ribbon cable is connected to
the EAP printed circuit board.

- Verify JP1 on the EAP 110 PCB has a jumper
connector on it (Jumper On = Run Mode)

from the Engine controller.

EAP 110 ANNUNCIATOR

SYMPTOM CORRECTIVE ACTION

Communication Fail Light is on - Check the communication cable is connected

properly on both the EAP 110 end and at the
MEC 2/MEC 20 engine controller end.
Notes:

1) On MEC 20 applications, ensure

communication cable is connected to the

Annunciator fault lights do not correspond to same
faults on the MEC Engine Controller

10. NOTES

MEC Expansion Port (J6) and
communication port (J7)

2) MEC 2 applications require software version

1.2 (or greater) software version for correct
EAP 110 operation.

- Verify the EAP 110 has the correct alarm group
addressing jumpers installed. Refer to section

3.2.3 for further information.
