Installation Instructions
The following instructions should be used to
properly install the PLEX-1 and PLEX-2 door

The PLEX door option is used in jurisdictions

panel. The PLEX door option protects the onboard annunciator with a UV stabilized
polycarbonate clear window. Once the panel
door is opened the operator can reset or silence
the control panel by pressing the Reset or
Silence button (no access code required).
