Flow Switch Check
While the green LED is flashing, turning the key to TEST will start a flow switch check. This should only be
carried out by or with the permission of Fire Safety personnel, after the main panel has been set ready for the
test. Failure to carry out this procedure in the correct order could result in a false alarm condition. If the key is
left in this position, the unit will timeout back to its normal ON mode. To start a test if the key has been left in
the TEST position and timed out, the key must be returned to ON position and then re-set to TEST.
