Power & Pressure Failure Detection System
–
PPFDS (where applicable)
The panel is designed to be used in conjunction with the Beacon unit to provide warning of either loss of
power or air pressure failure.
For panels mounted outside the blower housing, additional tubing can be purchased, contact your local sales
team for details. The panel can be mounted up to 30m away from the blower with no effect on the
performance of the pressure failure detection system.
To prevent damage to the PPFDS hole is fitted with a nylon bolt and nut. If the PPFDS is to be used, replace the
bolt with the air inlet bulkhead fitting supplied inside the control unit. A short length of 4mm silicone tubing
and a cable tie is also supplied. Connect the tubing from the bulkhead fitting to the
Top Port
of the pressure
switch, SW2, see Figure 5. Tie the cable tie on the pressure switch to prevent the tubing slipping off as it is not
barbed.
