2.2.10
Duration of Discharge
**************************************************************************
NOTE: For sprinkler and monitors discharge
duration, consult NFPA 409. For hose station
discharge duration, consult NFPA 30 and NFPA 409.
**************************************************************************
System shall apply foam solution over the sprinkler discharge area for a
minimum of [10] [_____] minutes while simultaneously discharging foam
solution through monitors for a minimum of [10] [_____] minutes. Hose
station discharge time shall be a minimum of [20] [_____] minutes.
Reduction of the discharge duration based on a discharge rate higher than
the specified minimum is not permitted.

ELECTRIC DETECTION DEVICES
**************************************************************************
NOTE: Electric detection system may be used with
all detector types specified in this guide
specification and are necessary for complex
controls.
**************************************************************************
Provide electric [heat detectors,] [and] [smoke detectors,] [and]
[combination ultraviolet-infrared detectors]. All wiring shall be
supervised and installed in protective metal conduit or tubing.
2.3.1
Control Panel
**************************************************************************
NOTE: Select either "Class B" or Class A"
supervision ("Style B" or "Style D" as defined by
NFPA 72). "Class B" supervision which will normally
be used, provides a trouble indication when a
failure occurs in a circuit. "Class A" supervision
provides a trouble indication when a fault occurs in
a circuit and at the same time allows continued
operation of that circuit. "Class A" supervision
should be used for strategically critical
facilities. Select first ("Class B") or second
("Class A") supervisory option accordingly.
