2-4.6 Discharge Pressure Switch
A discharge pressure switch (P/N: 03-5713-0000) may be installed (down-stream of any
selector valves) and provides a signal to the fire detection, alarm and control panel to indicate
that the Agent has been discharged into the pipe network. The maximum working pressure for
the discharge pressure switch is 90bar. Copper pipe (Ø8 x 1mm, as a minimum) may be used
to connect the pressure switch to the pipe network.
Optionally, the discharge pressure switch may be installed by using flexible hose (P/N: 01-
3272-1300) and a Nipple ¼” BSP male x ¼” BSPT male (P/N: 15-8662-0041) to connect hose
to pipe work. For more information on installation, see Section 4-16.

2-4.7 Odouriser
If required, the odouriser (K4135) can be installed in the discharge pipe work and will introduce
a distinctive citrus odour into the discharged Agent, such that it may be detected within the
risk when the Agent is present. The odouriser needs to be replaced once used and has a ½”
BSPT male thread for installation into the pipe work.
