Installing the DLA Controller
CAUTION: Provided mounting hardware must be used.
There are two options for mounting the DLA Controller: Flush
Mounted and Surface Mounted. Note: Mounting instructions
for custom assemblies including circuits in excess of 12
outputs are provided with the unit separately.
Flush Mounted (Figure 4)
Prior to installation:
The Controller easily mounts between two wall studs
within a minimum 6” wall cavity for flush mounting. If
stud spacing is greater than that required for the mounting
of the controller, add studs to insure a secured mounting.
The studs should be facing to facilitate securing the
controller.
Predetermine wall finish so that the face lip of the
enclosure aligns flush with the finished wall surface.
To install:
1. Using the self-starting screws (13), mount the flanges at
each side and at the top and bottom of the enclosure.
2. Attach the enclosure to the wall studs with field-provided
sheet metal screws. (See Figure 4)
3. Level the Controller.
Notes:
The Door Panel, when mounted onto the Controller,
should protrude beyond the wall surface about ¼”. Care
should be taken at installation time to ensure that this
occurs.
A Flush Mounting Trim Flange is provided with each
flush mounted unit. Separate installation instructions and
hardware are included with this kit. Flush trim adds 3.5
inches to both Height and Width Wall Surface
dimensions.
It is the responsibility of the installer to verify finish wall
dimensions.
Surface Mounted
(Figure 5)
Prior to installation:
Wall finishes must be complete.
The wall cavity must have sufficient backing or support to
ensure a firm mounting of the controller to the wall surface.
To install:
1. Secure the surface mount flanges to the back of the
enclosure with the self-starting screws (13).
2. Use the field-provided screws to attach the enclosure by the
flanges to the wall surface.
3. Level the Controller.
Figure 4 - Flush Mounted
*For best Flush Mounting results, recess
face of enclosure’s lip ½” behind wall
finish
Clearance around Enclosure:
Care should be taken to allow ½” clearance
from wall framing and sheet-rock or other
wall surface material around the outer surface
of the unit to permit the trim to be properly
installed.

Output Circuit Terminal
All DLA Controller should utilize 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.
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.
Do not connect more that 2 ISIMET provided latching solenoids to the output Terminal.
NOTE: This image shows the
wiring for each LA PCB
arrangement. The quantity of
these boards will differ for
each unit.

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.
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
ISIMET or your local 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 1 on each LA PCB 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.
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 patient 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.

Innovative Systems
Integrating
Mechanical and Electrical
Technology
ISIMET believes that sole and local authority means that the primary operator 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.
