d.
All alarms and associated circuits.
e.
All actuator circuits and system control valve(s) (without foam
discharge).
f.
Activation of the building fire evacuation alarm system.
g.
Activation of the Base fire alarm system (receipt of fire alarm at
alarm office).
h.
All of the above tests shall then be repeated with the system on
battery power only.
3.8.2.2
AFFF Discharge and Concentration Testing
When all of the initiating, alarm, actuation, and supervisory functions of
the system operate to the satisfaction of the system manufacturer's
technical representative and the Division Fire Protection Engineer, a
complete discharge test of each system shall be performed to demonstrate
satisfactory performance, proper AFFF concentration, mechanical operation
and operation of valves, release devices, alarms, and interlocks which
control the protected areas. These tests shall be conducted by experienced
personnel according to the equipment and AFFF manufacturers'
recommendations.
[a. Test each deluge system by full flow of foam solution from the
individual systems or combination of systems to achieve maximum
design flow rate for at least 60 seconds.]
[b. Test each pre-action system at their design flow rate for at least
60 seconds with temporary hose lines and nozzles connected to a
test header. Furnish hose and nozzles required for tests.]
c. Test all hose lines and monitor nozzles by full flow of foam
solution for at least 60 seconds.
The manufacturer's representative shall test samples of foam solution taken
from each system to ensure proper AFFF concentration. Provide protection
for all electrical fixtures and equipment exposed to possible damage during
tests and protect doors and other openings leading from the protected
area(s), to prevent migration of foam solution into other areas or spaces.
3.8.2.3
Flushing and Rinsing
After completion of tests flush all piping carrying AFFF concentrate and
solution with fresh water. Piping normally containing AFFF concentrate
when the system is in standby mode need not be flushed. Rinse with fresh
water all equipment and building surfaces exposed to AFFF discharge.

NOTE: Consult facility and the Division or District
environmental officials to determine local
requirements for containment and disposal of
discharged AFFF. In sufficient concentrations, AFFF
may cause disruption of processes in sewage
treatment plants and damage to fisheries. Edit the
