B-6 PNEUMATIC MAIN-TO-RESERVE VALVE
The pneumatic main-to-reserve transfer valve, Part No. 871364 (Figure B-5), is installed in
pneumatically-actuated systems having a connected main and reserve supply of carbon
dioxide, and is used to direct the pneumatic actuation signal to either the main or the reserve
pilot cylinders.
The valve contains an inlet port which is connected to two outlet ports. A toggle switch controls
a lever that transfers the pneumatic signal to one of the two outlet ports while blocking its
passage to the other. The toggle switch is normally placed in the "main" position. In the event
that the main suppression system discharges, the switch is placed in the "reserve" position to
provide uninterrupted fire protection while the main system is being recharged.

CAUTION
Never move the main-to-reserve transfer valve to the "reserve" position,
following a main suppression system actuation, unless the activating
detector(s) has/have cooled down.
