Comment on
Compliance
1. Scope
"watermist systems
with automatic
nozzles"
Descriptive
Does not use an automatic nozzle
as described in the definitions "an
integral quick-response
thermal release element" but
system does function
automatically using a thermal
element on the heat detector
Uses an open nozzle
configu automatic
heat detector. Complies
with performance.
5. System actuation
should be automatic
by glass bulb or
fusible link, initiated
by heat.
Descriptive
System is actuated automatically
by a heat detector.
Actuation is not by glass
bulb or fusible link, but it
is automatic and by heat.
Complies with
performance.
6.1 Fire Tests
When tested, nozzle
should suppress
fires for 10 minutes
for domestic or 30
minutes for
residential.
Performance
System run automatically for 30
minutes until stop button on
pump is pressed.
Complies with domestic
and residential
performance.
6.1 Fire Tests
Defines tests and
performance
criteria.
Performance
System has been tested
appropriate and meets all
performance criteria.
Complies with
performance.
6.2 Limits of
Application
Defines limits of
applicability.
3.5m or 5.5m high
32m2 or 80m2
Performance
Tests a,b,c,d and e have been run
so 3.5m high and 80m2 are tested
limits. Due to nozzle height from
wall, 5.5m high should not be an
issue if there are no fire loads at
3.5m and above.
Limits to be verified on a
case by case basis and
Plumis to be consulted in
case of doubt. A fire
engineering evaluation
may be required.
6.3 System Design
b) should be a wet
pipe system.
Descriptive
System is a dry pipe system.
Does not impact
performance and avoids
risk of Legionella
