General Product Information
The RLA Style 3 is intended as a control device to guard a residence from flooding due to domestic water leaks that may
occur when the residence is unoccupied. A latching solenoid valve will close, thus turning the water supply OFF.
Available options for the RLA Style 3 allow the controller to guard a part time or vacation residence from flooding due to
domestic water leakage that may occur due to freezing temperatures and also against seismic activity that may break piping
for gas and water service.
Construction
All electrical components are pre-assembled, wired, and mounted. The Electronic Controller is assembled within the
Utility Controller compartment.
The RLA Style 3 Controller has a powder coat finish. All panels and enclosures are constructed of welded 14-gauge sheet
metal.
Caution: Do not drop this assembly or expose it to the environment.

Equipment Operation
A dry-contact Input from a Building Alarm Signal connected to Terminal 1 will turn ON the Unit, placing
it in the OPERATE Mode. Removal of this signal will turn OFF the OPERATE Mode and turn ON the
SERVICE ON Mode.
The Unit may also incorporate freeze protection devices. A device similar to a thermometer with dry-
contact outputs that close upon a set low temperature will turn the Unit OFF. Additional latching
solenoid(s) could be incorporated into the system that opens upon the un-latch sequence, thus partially
draining the piping system.
The Unit may also incorporate a seismic sensor that will transmit a signal to turn OFF services to a
facility that if left on after a seismic event with potential breakage in piping or circuits may cause damage
to the facility. Integral time delay programming insures that brief seismic or similar activity will not affect
services.
To Activate One or More of the Services Controlled by the Unit:
(Refer to Users Guide)
1. From the Home Screen press Start System button.
2. Turn ON corresponding switch for the service you wish to activate.
To Turn a Service OFF:
Turn the appropriate switch to OFF.
Note:
A service left ON remains ON until its switch is turned OFF unless the Panic button is depressed
(Excluding Electrical Service), System Shutdown is pressed, or line voltage is removed from the
controller (When used with Battery Backup).
In Case of an Emergency:
Press the red panic button on the door panel. This will disable the panel and ALL services. Once the panic
button is pressed the Passcode must be re-entered to reset from panic. Also, the Panic Screen will remain
on until reset is accomplished.

Page 14
Troubleshooting Guide
If the Utility Controller fails to energize, follow these procedures:
Verify that the Controller has correct line voltage connected. With the control switch in the ON
position, the PLC “PWR” light should be illuminated. If it is not, check the wiring connections.
Remove the wiring junction-box cover and examine wiring connections.
Verify that Touchscreen turns on and initializes.
Touchscreen should start-up on the Home Screen.(Refer to Users Guide)
Verify that PLC Mode switch is set to “RUN” position.
Verify that the Door Panel plug is securely connected to the door terminal.
Check the wiring terminals on the door panel to verify that none has become damaged or disconnected
during installation. Reconnect, if necessary.
If services do not turn on with switches:
1. Verify that PLC Mode switch is set to “RUN” position.
2. Verify proper voltage at corresponding posts on Terminal 2.
3. If you do not read the correct voltage at the terminal posts, contact an ISIMET Service
Representative.
4. If you read the correct voltage, test the remote relay and/or solenoids to verify that they are
operational.
In many cases, failure of the system is the result of improper connection of a remote service or device such
as a remote relay, solenoid or building alarm system. Refer to Equipment Specifications to confirm that
correct connections to these services and devices have been made.
Notes:
Damage to the Electronic Controller and other components can occur from improperly connecting the
services, overloading the output circuits, or failing to follow all start-up tests and checklists.
In ALL cases, if the system fails or you have questions about the equipment, contact an ISIMET
Service Representative.
If the results of all test procedures are positive but utilities will not activate, ISIMET recommends that
you examine and test the various utility services controlled by the unit to verify that they are
operational and active.
If utilities or controlled devices remain operational after the service switch is disengaged, check for the
following before placing the unit into full operation:
A defect in the remote relay or solenoid
Tampering
The remote relay unit has a control switch with a manual operation position and the switch is in the
manual position.
If utilities or devices continue to be active or if you have a question about the operation of the unit,
contact an ISIMET Service Representative immediately.

Page 15
Equipment Maintenance
The Utility Controller should have semi-annual inspections.
ISIMET recommends opening the service panel and turning OFF the control switch prior to long
periods of inactivity in the building.
Prior to anticipated activity within the building, ISIMET recommends that you conduct a brief test
of the control system by performing Start-Up Test Procedure A and Step 1 of ProcedureB.
If examination of the unit indicates tampering, ISIMET recommends that you first review the Start-
Up Checklist, then conduct ALL Start-Up tests.
ISIMET recommends that the door panel key be kept in a secured location. The door panel key
should be available only to those needing access to the interior of the unit for the purposes of
maintenance or service. ISIMET recommends that the door panel remain locked unless service is
performed.
If you have any questions regarding the operation and maintenance of the RLA Controller, please
contact an ISIMET Service Representative.
The enclosure has a NEMA 1 rating. It is not intended for use in wet areas. Exercise caution to prevent
exposure of the interior compartment of the enclosure to moisture. If moisture is present within the
enclosure, ISIMET recommends that the control switch be turned OFF, power be disconnected from
the unit until the source of the moisture is determined, and all moisture is removed from the
compartment.
The electronic controller (PLC) is sensitive to moisture, dust, debris and other air-borne particles. Do
not expose the interior compartment of the enclosure. During the semi-annual inspection, if dust or
other material is present, ISIMET recommends that you remove all foreign matter before operating the
unit.
If the Unit fails to operate, we recommend that you check the power supply to the unit. With the
control switch in the ON position, the PLC “PWR” light should be illuminated if power is on to the
unit. If not, check the service breaker.
If the unit still fails to operate, we recommend that you contact your local Service Representative.
Removing the Door Panel
Before removing the Door Panel, turn power OFF at the control switch, then disconnect the plug from
the terminal within the enclosure.
Follow steps 1 –4 in reverse as shown in Figure 6.
Instructions for Re-coating the Enclosure
If the finish surface of the enclosure or door panel becomes scratched, follow this procedure to repair
the surface.
Most standard, good quality paints can be used to re-coat the polyester powder finish.
For best results, correct surface preparation before re-coating is essential. Follow instructions
provided by your paint manufacturer.
Wipe surfaces to be painted with either xylene or lacquer thinner solvent.
Allow surface to flash dry prior to painting.
Follow paint manufacturer’s instructions for applying paint.
Allow paint to cure adequately. Consult the paint manufacturer for proper cure time and hardness.

Page 16
ISIMET believes that sole and local authority means that the primary operator or the
instructors should have the sole authority to start and stop the utility services within
the immediate area of use during normal usage. This should distinguish this type of
operating environment from that where a single emergency shut-down device is
located remotely from the areas of use. As an example, the ISIMET system is not
specifically intended for use in applications where a master shut-down and re-instate
device is located away from areas of normal use. ISIMET’s opinion is that in such
cases there is risk that the operator of the system during re-start may inadvertently
activate utilities in an unoccupied area that is remote from the present occupancy,
thus creating the risk of injury and/or fire where the utility is fuel gas.
