Preaction trim options
1. Shut-off valve & sight glass
The shut-off valve & sight glass option is intended to be
used for applications where testing of the system operation
without filling the sprinkler piping network is desirable and
where it is critical that all functions of the preaction system
be tested under actual discharge conditions. Examples of
such applications are freezers, ovens, museums, data
processing and other hazards where the possibility of
water leaking from the piping system is to be avoided at all
costs.
Operation of the shut-off valve
Inspection of the system can be implemented without filling
the sprinkler piping network with water.

the sprinkler piping network shut-off valve
(D4)
;
the valve is supervised on the same circuit as the main
water supply valve

3. Simulate the operation of the system to open the deluge
