The Guardian III system enclosure consists of the pressurized extinguisher cylinder with the chemical fire suppressant, central processing unit (CPU) control board with terminal block connections, solenoid mechanical release valve, cylinder pressure gauge, enclosure base, and enclosure cover.

The CPU control board monitors the temperature above the cooking area and is equipped with an audible alarm that will sound if the system is activated. It also monitors the battery voltage and will chirp when the battery needs to be replaced.

Electric

The Electric Shutoff Assembly G319-A is the standard shutoff supplied with the G300B system.  Features provided with this shutoff include the following:

1. A “Fail Safe Mode” consisting of a Normally Open (N/O) Contactor that is energized continually. Activation due to a fire will open the contactor, disconnecting "electrical power” supply lines to the stove.

2. Standard interface interconnect cable will be provided or optional “Sonic Receiver” board upon request.

3. Two extra set of dry contacts for switching external devices during system activation are provided via opyional Interface Enclosure Assembly.

4. The shutoff also has a latching feature to eliminate any possibility of an automatic reset of the power supply after a fire. To restore power to the stove simply disconnect power to the electric shut off device by flipping its breaker off and then on again.

Gas

The Gas Shutoff Assembly G316-A is the standard shutoff supplied with the G300B system.  Features provided with this shutoff include the following:

1. A “Fail Safe Mode” consisting of a Normally Closed (N/C) valve that is energized continually.  Loss of power or activation due to a fire will close the valve, shutting off “gas flow” and “electrical power” to the stove.

2. Standard interface interconnect cable will be provided or optional “Sonic Receiver” board upon request.

3. An extra set of dry contacts for switching external devices during system activation are provided.

4. The shutoff also has a manual “power reset” feature to eliminate any possibility of an automatic reset activation of the valve occurring after a fire or loss of power.

The sensor assembly, which is temperature activated, consists of two (2) metal housed detector assemblies.

The sensors are easilly installed by placing them next to the nozzle assemblies magnetic base, which holds them in place

The distribution assembly consist of two (2) Teflon lined stainless steel braided hoses and two (2) magnetic based adjustable nozzle assemblies.

The nozzle are mounted onto a magnetic base that secures the nozzle and sensor to the inside of the hood. The distribution assembly is pre-assembled with quick connect fittings for easy installation.

The optional Interface Enclosure Assembly (P/N G317-A) is provided to allow easy interfacing to external devices i.e., automatic telephone dialers, monitored security alarm systems or other warning / protective equipment.

The Interface Enclosure Assembly provides one set of dry contacts when connected with the Gas Shutoff (P/N G316-A) and two sets of dry contacts when connected to the Electric Shutoff.  Contact rating is 120 VAC 5 amps.

The optional Sonic Receiver Assembly will work with either any configuration of Electric Shutoff (P/N G319) or the Gas Shutoff (P/N G316-A). Some site conditions have difficulty installing the standard Interconnect Cable from the Main CPU control board.

For convenience and ease of installation, the Sonic Receiver Assembly provides a remote sonic activation.

Both the electric shutoff and gas shutoff provide connections for interfacing a (120 volt-5A) alarm / strobe.

This assembly has a Plug & Play configuration for ease of installation.  Install in optimum location for visibility.  This feature is mainly used for the strobe function.

A manual remote pull station is available where local fire codes or circumstances require the capability to manually activate the range top extinguisher system.

Manual activation of the system will cause the extinguisher unit to fully discharge extinguishing agent, shut off the range top burners and activate the alarm or other electrical accessory.

The Manual pull station comes fully assembled and gets wired into the main CPU.
