the addition of freeze suppression compounds or other provisions. The cylinders shall be
factory fitted with a shield to protect the gauge and, where applicable, pressure switch.
The shield shall be a separate assembly from that of the gauge, and shall be separately
4. Sufficient cylinder/valve assemblies and discharge nozzles shall be provided to protect

explicitly approved by third-party agency, e.g. FM, for the purpose.
4.2 System Control Panel
A. The system control panel shall be capable of all functions associated with automatically and
manually discharging the dry and/or wet chemical agents from all cylinder and valve
assemblies, including automatic shutdown of the ignition/heat source and/or fuel and
electrical power to all protected areas upon system discharge.
B. All connections will be made using Deutsch brand connectors.
C. The control system shall include built in RFI protection and shall be capable of field
programming directly from the front panel without having to open the control unit.
D. The control panel shall be capable of being powered directly from the machine’s battery
source (12 to 24 volts nominal) or provide its own power source from a primary cell battery
with a minimum one (1) year service life.
E. The control panel and power supply shall have an operating temperature range of -40°F to
158°F (-40°C to 70°C).
F. The control panel shall include a troubleshooting mode that provides fast feedback for
troubles annunciated in the system.
G. The control panel module(s) shall have the capability to accept dual spectrum infrared (Kidde
Fire Systems model IR1A) detectors, watertight rate compensated heat detectors, linear heat
cable and/or any combination of the three.

H. Where vehicle power is used, all circuits shall be supervised and the system shall have the
option to provide for a one-hour battery back up as a secondary power supply in the event of
vehicle power loss.
I. The control panel shall be IP66 and NEMA 4 approved and shall be constructed of die-cast
aluminum, with a red powder-coat finish.
J. The control panel shall have a separate supervisory circuit that allows for supervision of the
