NOTE: This module is not approved for use in the European Union, at or above 50VAC or 70VDC.
This information is included as a quick reference installation guide. Refer to the
appropriate control panel installation manual for detailed system information.
If the modules will be installed in an existing operational system, inform the
operator and local authority that the system will be temporarily out of service.
NOTICE: This manual should be left with the owner/user of this equipment.
Relay Module, Model EM-1RI, is to be designed for use in activation of the
types of products that are generally connected to an intelligent fire alarm sys-
tem. It provides two sets of form C contacts that switch together (one DPDT
relay). There is also an input that is capable of monitoring a dry set of contacts
for open or closed conditions. The module also has on-board short circuit iso-
lators to prevent shorts on the signaling line circuit from disabling more than
one device on the intelligent loop.
To ensure proper operation, this module shall be connected to a listed compat-
ible control panel.
The module mounts directly to 4-inch square electrical boxes. The box must
have a minimum depth of 21⁄8 inches. Modules must be mounted with the ar-
row facing upward for proper operation of the IR programming tool. Surface
mounted electrical boxes (SMB500) are available from System Sensor.
NOTE: All wiring must conform to applicable local codes, ordinances,
1. Install module wiring in accordance with the job drawings and appropri-
ate wiring diagrams.
NOTE: Separate cable entry openings must be used to maintain required
spacing between power limited and non-power limited wiring. Optional
EA-CB may be required to separate power limited and non power limited
wiring in the electrical box.
2. Set the address on the module per job drawings using the IR configura-
tion tool (model no. EA-CT).
3. Secure module to electrical box (supplied by installer).
Eclipse Series devices are capable of supporting auto addressing, if the fire
alarm control panel is designed to do so. In auto addressing, the control panel,
through the use of each device’s on-board isolators, can automatically assign
In order to control which devices are addressed first in wiring configurations
with branches, a branch marker can be set at a particular device. A branch
marker is an electronic value from 0 to 255 stored in the device memory. The
branch markers are set with the IR configuration tool, EA-CT.

All relay switch contacts are shipped in the standby state (open) state, but may
have transferred to the activated (closed) state during shipping. To ensure that
the switch contacts are in their correct state, modules must be made to com-
municate with the panel before connecting circuits controlled by the module.

Three-Year Limited Warranty
System Sensor warrants its enclosed module to be free from defects in materials and
workmanship under normal use and service for a period of three years from date of
manufacture. System Sensor makes no other express warranty for this module. No agent,
representative, dealer, or employee of the Company has the authority to increase or
alter the obligations or limitations of this Warranty. The Company’s obligation of this
Warranty shall be limited to the repair or replacement of any part of the module which
is found to be defective in materials or workmanship under normal use and service
during the three year period commencing with the date of manufacture. After phoning
System Sensor’s toll free number 800-SENSOR2 (736-7672) for a Return Authorization
number, send defective units postage prepaid to: System Sensor, Returns Department, RA
#__________, 3825 Ohio Avenue, St. Charles, IL 60174. Please include a note describing
the malfunction and suspected cause of failure. The Company shall not be obligated to
repair or replace units which are found to be defective because of damage, unreasonable
use, modifications, or alterations occurring after the date of manufacture. In no case shall
the Company be liable for any consequential or incidental damages for breach of this
or any other Warranty, expressed or implied whatsoever, even if the loss or damage is

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used
in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installa-
tion. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following measures:
– Reorient or relocate the receiving antenna.
– Increase the separation between the equipment and receiver.
– Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
– Consult the dealer or an experienced radio/TV technician for help.
