the red boxes, do they trigger the fire alarm?

[twoplyboy]

theres a few red boxes here....but if they are the ones i think your talking about, yes they do.

[jooiiee1]

just heard that in the old days when we had sprinklers in my school we had FACP trigged sprinklers and somebody activated it, water in lines for 15 years is not so fresh any more...... they did not like it...

[twoplyboy]

yeah it would pretty stale water thats for sure.

@twoplyboy why they keep stale, dirty, stink, black... in sprinkler pipes ?

[twoplyboy]

@paul9511 they only get flowed so often (once a year) that it just gets that way.

the "red boxes " are flow switches from potter and are a set of contactors they delays are usally programmed from the FIP or controller

its a aux drain because its a smaller drain usally to set off pressure switches and the flow switches. the main drains can be a 2' or a flow test valve in different sizes

and the stale smell is yes water and usally the bactricide and hemp thread tape

times vary from state to state country to country

still though its the most relible fire suppression system

@leelwfp they are adjustable from 0 to 90 secs 

[leelwfp]

@JJJMeininger9  60 sec

ya there called flow switches there suppose to have 30 sec delay on them

[JJJMeininger9]

and what does nfpa 25 state the max flow switch time should be?

這才算是實地測試~!!

總比因為不實地測試~

所帶來嚴重的損失
