Monitoring Circuit- JP3
Output Configuration Jumpers
@ Panic Output
1 jumper across center two posts
= dry-contact @ CON 5-a.
2 jumpers across each pair of posts
= 24-vac output @ CON 5-a.
CON 5-b is always dry-contact.
Output Circuits
Where Reset Switches are provided @ Output Terminal, DO NOT Bypass.
12-vac Output is intended for use W/ ISIMET Fuel Gas Sensoe and CO Sensors where required by manufacturer.
Care should be taken to insure that polarity is correct in order for 12-vdc solenoids to function as intended.
WARNING!! Other pcb Jumper placements
Jumpers at JP 1, JP 4 and JP 5 are factory placed in order to configure the circuit board to specific functions for the
Controller. Removal and/or re-placement may cause the unit to malfunction.
Output Terminal:
120-vac Solenoid(s) connected to1 & 2 @ Output Terminal
OR 1& 2; 1 & 3 where 2 120-vac Solenoids are provided.
24-vac Solenoid connected to 3 & 4 @ Output Terminal.
NOTE: Only make conections of solenoids @ Terminal
Posts specifically marked as Solenoid Output.

6
Installing the Electrical Conduit:
Knockout holes for connecting the electrical conduits are located at the top left and right of the Wall Box.
•Connect rigid conduit for the required 120-vac electrical service.
•Connect conduit for the operating power to the upper left top of the enclosure at the junction box.
•Connect conduit for the operating power for the output to the upper right top of the enclosure.
Wiring the Unit:
Important!
Verify that the electrical supply is disconnected prior to connecting wiring to the Utility Controller.
To wire the Controller:
1. Remove the junction box cover.
2. Make final connections to the 120-vac electrical service to wiring within the junction box. Verify that line
wiring (Black), neutral (White), and ground wire (Green) are correctly connected.
Minimum recommended wire size is 14 AWG.
3. Replace the junction box cover before activating or testing the unit.
Output Wiring Configurations:
The Unit is factory configured as either 24-vac or 120-vac outputs. Two to Four output terminals are provided
based on specifications for the Unit. The unit is equipped with a dedicated 120-vac rated at 15 amps for connection
of a single convenience outlet circuit. See page 5 for typical wiring schematics. Do not attempt to modify the unit
to accept other than voltage outputs as specified for the unit. To replace a PC Board not configured correctly for a
specific application, contact the factory or a local representative.
Optional Input Control circuit:
“EMS” Input: 24-vdc /vac active OFF will disable the operation of the unit.
Alarm Input: 24-vac/vdc active OFF. Refer to jumper configuration chart above. Make connection of this optional
wiring at CON 4.
Optional Remote Panic Input Connection:
An optional input from an ISIMET Remote Panic Assembly can be connected to the PCB at CON 4-a.
Optional Panic Output Terminal:
A configurable Panic output is activated at CON 5. See configuration chart and location of this connector
on page 5.
Connection of the Wall Panel Plug:
The Unit is equipped with a 9 pin d-sub connector
•Turn counter-clockwise the two retaining clips at the top of the Panel, and open.
•Insert plug onto circuit header on PCB.
•Turn Power ON.
•Close the panel and lock.
CAUTION! Do not install the panel until all wall finishes are complete. Verify that the plug is configured
correctly. Incorrect insertion will prevent operation of unit.
Important!
All local codes must be followed when installing the unit and connecting the conduit to the service panel and
making wiring connections. Do not install wiring or cable for integrated systems, remote panic assemblies or
other interface wiring within conduit for either 24-vac control or 120-vac line voltage. Each wiring system
including outputs should be housed in independent conduit and not bundled with wiring for other systems.

7
Failure to comply with these wiring specifics may create transient voltage at the pc board and cause system
malfunction and/or failure.
Operation of the Unit:
CAUTION: Having outlets such as Gas Turrets Open when Services are activated can result in injury or death.
Verify that these outlets are closed prior to activating the unit.
With the panel service switch(s) ON, engage the Key-switch. The circuit(s) will activate and the panel Green LED
will illuminate to indicate that the services are active. After turning a switch OFF, it will be necessary to re-engage
the Key-switch in order to reactivate the services.
After turning the switch OFF, it will be necessary to re-engage the key switch in order to reactivate the service. The
Red LED will illuminate when the services are OFF.
Pressing the panic button will deactivate the services. All Panel lights should illuminate with Panic.
Receipt of an Alarm Signal will deactivate the services. All Panel LEDs will illuminate and all output circuits will
turn OFF.
Once in Panic or Alarm Modes the Key-switch must be engaged in order to reactivate service. The Alarm Signal
must be withdrawn prior to reactivation.
Power to the solenoids should be turned OFF when utilities are not in service.
Equipment Maintenance:
The LA Series Controller should have semi-annual inspections.
ISIMET recommends that you periodically conduct a brief test of the system to verify that the output circuit
performs as intended.
If examination of the unit indicates tampering, ISIMET recommends that you first review the installation and
wiring portions of this manual prior to placing the unit in service.
ISIMET recommends that when solenoids are operated by the unit, the piping systems be thoroughly flushed
and cleaned and tested for leaks prior to placing the system into use. Periodic testing of these solenoids will
assure that the piping system continues to function properly.
If you have any questions regarding the operation and maintenance of the Utility 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 (PCB) is sensitive to dust and other air-borne particles. Do not expose the interior
compartment of the enclosure to dust. 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, ISIMET recommends that you check the power supply to the unit. With the control
switch in the ON position, LED Fuse 1 should illuminate. If not, check the service breaker.
If the fuse is not damaged and the unit still does not function, contact ISIMET or your local Service Representative.
CAUTION:
ISIMET DOES NOT recommend that service to emergency and/or safety devices, such as emergency
showers and eyewashes, be controlled by the Utility Controller System or Solenoids. Such devices are
intended to operate independent of restrictive authority operation, as is the case with the design of this unit.
ISIMET makes available components for the monitoring of such safety devices. Please contact ISIMET
regarding any questions regarding this type of application.

Mechanical and Electrical
Technology
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.
