Electronic Fire Commander

Question 1

Fire commander (I): what is the PSI increase with pressing vs pressing and holding the increase button?

Answer 1

4 vs 8

Question 2

Fire commander II: What is the PSI increase with pressing vs pressing and holding the increase button?

Answer 2

1 vs 5 for first two increases and then auto switches to increments of 10.

Question 3

What is the appropriate RPM for priming?

Answer 3

1000-1200 RPM

Question 4

What are the steps for priming the pump?

Answer 4

Place the pump in RPM mode and ensure 1000-1200 RPM
Pull prime till steady water flow is discharging from the priming pump. 50 PSI should then be visible on discharge, and the pump can be shifted back into pressure mode.

Question 5

What is the PDP when in idle and pressure mode (not the transfer valve setting)?

Answer 5

50 PSI

Question 6

At what point does the Fire Commander pump assume cavitation? Fire commander II?

Answer 6

Fire Commander I: Any situation which causes a drop below 30 PSI for more than 5 seconds or a sudden increase of 400 RPM.
Fire Commander II: Drop of 45 PSI for 7 seconds.

Question 7

If there is a sudden loss of water supply, what must be done immediately?

Answer 7

Press idle

Question 8

What will cause a loud audible alarm?

Answer 8

Low voltage, low oil pressure, and overheating.

Question 9

If the EFC fails to operate, what can driver do to produce pressure?

Answer 9

Shut down and restart.
If that doesn’t reset the system: ensure transfer valve is in pressure on a two stage pump. This will supply approximately 60 PSI at idle pressure
