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 DLA 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.
Optional Input Control circuit:
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 electrical codes must be followed when 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.
Failure to comply with these wiring specifics may create transient voltage at the pc board and cause system
malfunction and/or failure.
Output Circuit Terminal:
The solenoids provided are ISIMET S-200 or S-220 Series General Service Brass Valves with 12 vdc coils.
These coils are polarized and must be connected correctly to the Output Terminal in order to function as intended.
Connect Supply Solenoids to the ‘ON w/Latch Terminals.
Connect Drain-down Solenoids (where provided) to the ON w/Un-Latch Terminals.
Make connections to ‘BLK’ and ‘WHT’ pins to match instructions provided with the solenoids that are similarly color coded.
Piping and wiring for solenoids should follow details provided with the solenoids.
Pins 1, 2, and 3 are provided for connection to an optionally provided 24v beacon. This beacon indicates whether the facility is
occupied or non-occupied.

Operation of the Unit:
With the panel service switch ON, engage the Key-switch. The circuit will activate and the panel Green LED will
illuminate to indicate that the water services to the testing restroom are active. After turning a switch OFF, it will be
necessary to re-engage the Key-switch in order to reactivate the services. The Red LED will illuminate when the
circuit is OFF.
Pressing the panic button will deactivate the services. All Panel lights should illuminate with Panic.
Once in the Panic Mode the Key-switch must be engaged in order to reactivate service. The Alarm Signal must be
withdrawn prior to reactivation.
This unit utilizes latching solenoids that pulse ON with circuit active to open the water supply and pulse OFF with
circuit inactive to close it. Where provided, secondary solenoid(s) are provided that pulse ON when inactive in
order to provide drain-down of supply piping.
Equipment Maintenance:
The DLA 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 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 DLA 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 and PCB fuses.
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 DLA 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.

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.
