3-11 TYPICAL FLOOR LOAD
Use these table to calculate the floor load of the cylinder bank.
3-12 VIBRATIONS
Give due consideration to cylinder installations in a storage room exposed to constant
vibrations as well as storage rooms exposed to vibrations in the form of shock.
Agent cylinders subjected to vibrations may need to be installed on a “soft” plate between the
floor and the bottom of the cylinder and between wall brackets and cylinders in order to avoid
momentary low-pressure alarm signals caused by chattering of the contact in the contact
pressure gauge.
3-13 AGENT CYLINDER RELEASE CONSTRAINTS
Each valve shall be actuated no more than 50 times. (The valve has been tested for 100
actuations at 300 bar at the BAM institute and 500 actuations (300 bar) at FM without
comment.
The cylinder valve is capable of emptying a cylinder pressurized to 300 bar within 60 seconds.
A typical cylinder bank can be emptied within 60 to 120 seconds. The emptying rate produces
a high discharge thrust at the valve outlet port, however the valve does limit the discharge
pressure to the same level regardless of cylinder pressure. The discharge thrust is
approximately 278 lb-force (126 KG-force). These forces shall be neutralized by the cylinder
brackets.
