Isimet Utility Controller Safety Device

The Utility Controller is a Safety Device that regulates the control of various utility services and devices such as domestic water, natural gas, and electrical outlets within a science classroom, other instructional facilities, research and medical facilities. The solid state electronic controller provides an electronic signal to relays that in turn provide electrical current to relays and contacts, activating the utility service.

A keyed service switch integrated into the design of the Utility Controller restricts the ability to activate the utility services, resulting in a safe environment for the students or other occupants. This unique design permits any occupant of the classroom to deactivate the service while allowing only the instructor or supervisor to activate the service.

The Utility Controller is easily integrated with other building services often found in many public facilities. The same "EMS" (Energy Management System) that controls and activates the heating and cooling system for the room will provide a higher degree of authority to activate the room utility services. Disengaging the "EMS" at the end of the day will deactivate the Utility Controller and the controlled utilities. At the beginning of the next day, the Utility Controller will remain dormant until it is reactivated by the keyed service switch.

The Utility Controller is easily integrated with a building alarm system. Pressing the panic button, located on the front door panel, will alert the administrator that a possible emergency has occurred. The Utility Controller and all controlled services will become inactive. The Utility Controller can become operational only after re-keying (optional) or by opening the door panel and pressing the RESET switch.

Optional Output Circuits:

An additional switch to operate devices such as an exhaust fan or fume hood can be placed on the door panel. Additionally, a remote circuit can be added so that the installer can provide an additional remotely switched circuit that may be used to control another solenoid or a secondary fan.

Utility Controller Features

This Utility Controller focuses primarily on specific needs of facility designers, engineers, and owners. It can easily be modified to meet individual design criteria of any project. Many modifications required by the design of both new and renovated facilities are achievable.

Optional Features:

• Panic Button - included with the unit; can be omitted
• Auxiliary output circuit can be added
• Remote auxiliary circuit is available
• Pre-assembled enclosures with remote relays and/or solenoids.

Cabinetry:

• Powder Coat Finish or Brushed Stainless (12 X 10 X 4 plus 0.625” door flange)
• NEMA 1 Rating
• UL Listing
• Concealed Hinges
• Removable Door Panel
• 180° Door Opening Patent 6,757,589 B1

Wiring Connections:

Service wiring connections are located in a cover-protected junction box. Side and top knock-out holes permit either type of service connection.

Integrated Services:

Integrated services include remote timing devices such as a building Energy Management System, a digital timer, and a monitoring system such as a building alarm system. The system can be further configured to accept an AUTO-Shutdown signal from an alarm system when the fire alarm is active.

Control Switch:

The illuminated main control switch located on the interior service panel facilitates activation of the Utility Controller and deactivation during periods of non-use and for servicing.

Reset Switch:

The Reset Switch located on the PC Board enables an authorized user to re-activate the unit after a panic state, which results from pressing the panic button on the door panel.

Controlled Service Circuits:

Wiring connections for controlled utilities and electrically controlled devices are made at Terminal 2. All terminal posts are pre-configured to door panel switches with a schematic provided in the unit.

Printed Circuit Board:

The Printed Circuit Board (PCB) enables the Utility Controller to logically control the output signals. The programmable logic device is the primary component that controls the logic states of the unit. Solid state relays provide output current to the output terminals on the PCB. The PCB is configured for 24 vac output current and for either AC or DC inputs from integrated automation systems.

Door Panel:

The Door Panel houses all standard user devices that activate and deactivate the unit. The Service Switches are configured to the Output Terminals, thus enabling the activation and deactivation of the corresponding controlled device or utility. The keyed switch prevents unauthorized users from activating the utility devices. Pressing the Panic Button places the logic controller into the Panic State. The keyed lock prevents access to the interior service panel by unauthorized users.
