The NY-700 New York module provides a disable key switch for disabling all user operated switches on the Fire Command Center (FCC). When the Key Switch is placed in the “DISPLAY MODE” position, the CP-40 Control Panel or GCP-70 Graphic Control Panel displays “FCC LOCKED”. All user-operated switches on the Control Panels and Display Control Modules (DCM’s) are inoperable. The key lock is keyed with the NYC Fire Department 1620 cylinder. To enable all user-operated switches, turn the key switch to the “NORMAL MODE” position. No field wiring is required.
