Table 25 — Smoke Control Switches — PIC Controls Units
(48ZJ,ZL,ZW)*
*Units with PIC controls require installation of Controls Option Mod-
ule (PSIO2), via factory-option or field-installed accessory, for
implementation of any Smoke Control mode.
NOTE: All switches are shown in ‘‘as installed’’ (power OFF or deen-
ergized) position. In these positions, none of these modes will be
activated and normal unit operation is permitted by the base unit
controls. To initiate any mode, all switches listed under this mode in
the table must be energized, causing the contact position to change
to energized position. Switches may be manually or electrically
operated.
