Fire Suppression System

Water Requirements

IMPORTANT: Water must be supplied to the fire suppression system, or the fire suppression system will not operate as intended.

Connection point to the electric water solenoid valve is a 19 mm (3/4 inch) hose. The fire suppression system equipped tumbler must be supplied with a minimum water pipe size of 12.7 mm (1/2 inch)and be provided with a minimum of 138 kPa (20 psi) and a maximum of 827 kPa (120 psi) of pressure at all times. Flowrate must be no less than, but approximately 57 liter

(15 gallons) per minute.

NOTE: Water pressure under 138 kPa (20 psi) will cause low flow and water leakage at water solenoid valve.

IMPORTANT: Temperature of the water supply must be kept between 4.4° and 48.9°C (40° and 120°F). If water in the supply line or water solenoid valve freezes, the fire suppression system will not operate.

IMPORTANT: If temperature sensors inside the tumbler register a temperature below 4.4°C (40°F), the fire suppression system control will lock out. This feature protects against operation of the tumbler with a possible frozen water supply. Only when the temperature sensors register a temperature above 4.4°C (40°F) will the machine reset for operation.

IMPORTANT: Flexible supply line/coupling must be used. Solenoid valve failure due to hard plumbing connections will void the warranty. It is recommended that a filter or strainer be installed in the water supply line.

IMPORTANT: Thread hose couplings onto valve connections finger tight, then turn 1/4 turn with pliers. Do not cross thread or overtighten couplings.

IMPORTANT: Replace all hoses every five years.

NOTE: Longer inlet hoses are available (as optional equipment at extra cost) if the hoses supplied with the tumbler are not long enough for installation. Order hoses as follows:

Part No. 20617 Inlet hose 2.44 m (8 feet) Part No. 20618 Inlet hose 3.05 m (10 feet)

Electrical Requirements

WARNING

Electrical power must be provided to tumbler at all times. The fire suppression system will be inoperative if the main electrical power supply is disconnected.

W690

No independent external power source or supply connection is necessary. Power to operate the 24 Volt fire suppression system is from the rear junction/ contactor box.

Auxiliary Alarm

During tumbler installation, you have the option to connect a separate alarm system to this auxiliary output. Use of the auxiliary output is not required for the fire suppression system to operate, but may be used for additional protection.

NOTE: The auxiliary output is activated during fire suppression system maintenance test sequence. Consider this fact prior to your system test every three months. (Example: If the external system uses the auxiliary output to call the fire department, inform the fire department before and after the fire suppression system maintenance test.)
