Pressure switches
Two pressure switches inputs are available for use with the FSM panels. If the panels are being installed in
conjunction with Chubb PEFS systems, the switches that are specified for use are;
1. “Pressure Low”, 1,200kPa setting (part number 87042)
2. “Discharge”, 200kPa setting (part number 87041)
Both switches have a 1/8”NPT thread connection and are kitted with an IP65 rated Deutsch DTM series
connector. The pressure switch inputs on the panels are configured for ‘Normally Closed’ (N/C) i.e. contacts
closed = normal operation, contacts open = low pressure/discharge.
