ISIMET is committed to providing quality safety products for use in the laboratory classrooms of our Nation's Public Schools. Placing special emphasis on Student and Instructor safety is the focal point around which we development our Utility Controller Safety Control System.
Our innovative Utility Controller provides not only a safe instructional environment for the Student but likewise a safe work place for the Instructor. "Viewing the ability to cope with emergencies from two prospective views, response and prevention." - we believe that our Safety System uniquely addresses both concerns in ways that are often overlooked by other designs and products.
We at ISIMET feel that our concepts for Public School laboratory safety control devices will become more than that of an optional convenient control apparatus, but rather a standard whereby future classroom design is based.

1.4.1 Utility Controllers shall be factory configured to the required configurations and shall be capable of field adjustments to meet specific project modification requirements. Configurations shall be limited to specific placement of jumpers at PC Board and Circuit configurations to the operating code without requirement for additional modifications to equipment.

1.4.2 Classroom Utilities:

1.4.2.1 Each utility service with outlets at student work-stations shall be controlled by independent output circuit at the Utility Controller. Control of services shall not be combined onto one output circuit unless indicated on Drawings. Services shall be activated by Controller door panel switches and the engaging of the service enabling key. Activation of utility services shall be restricted to the Instructor by means of the enabling key switch. Where systems include domestic hot and cold water, then a single output circuit shall control those systems simultaneously. Where shown on drawings, compressed air system shall be controlled by an auxiliary output circuit.

1.4.3 Energy Management Control System - "EMS"

** NOTE TO SPECIFIER ** Verify that Controller is field configured to accept specified control signal from energy management control. Verify voltage of control signal prior to placing the unit into service.

1.4.3.1 Each Utility Control System shall be configured so that all controlled utilities and devices disengage at the end of the daily occupied period. Withdrawal of the low voltage control signal from the Energy Management Control System at the room's air handling device shall disable the Controller during the non-occupied "EMS" mode. Signal shall originate from either a 5 VDC point on the unit's PCU or from 24 VAC dry contacts. Controller shall be reactivated upon return of control signal.
