control sequences. The BHSC shall coordinate with Fire Alarm System (FAS)
contractor for interface programming and connection requirements.
1) The interface of the BHS to the FAS will be one (1) dry contact closure at
the MCP (which is controlling the fire doors). The BHSC’s responsibility
shall wire to the dry contact and ensure that when a signal is sent to the dry
contact from the FAS, that the conveyor segment of the conveyor line shall
shut down appropriately (i.e., the conveyors will stop, ensuring that no bags
are in door openings and if so will advance enough to clear the openings,
and then the security/fire doors will come to a fully closed position). The
GC/Electrical/Specialty contractor will supply the dry contact. See the FAS
drawings for the location of this contact. The GC/Electrical/Specialty
contractor will wire them back to the FAS, and ensure that when the FAS is
in an alarm condition that the dry contacts will send that signal.
d. Interface with CCTV: There is no interface between BHS and CCTV.
e. Interface with Common Users Terminal Equipment (CUTE): There is no interface
between BHS and CUTE.
f. Interface with Airline Departure Control System (DCS): There is no interface
between BHS and DCS.
g. Interface with Fight Information Display System (FIDS): There is no interface
between BHS and FIDS.
h. Interface with Bags Information Display System (BIDS): There is no interface
between BHS and BIDS.
i. Interface with Master Clock: There is no interface between BHS and Master
Clock.
j. Hold-In Circuit: A hold-in circuit shall be provided to ensure that all timers shall
stop and not time-out whenever a system is stopped by either a jam or emergency
stop so that no baggage can generate false alarms or become stranded between the
load belt and the bag room.
k. Jams Sensors:
1) Jam photoelectric sensors shall be positioned at the discharge end of all
conveyors except the conveyors are located in public view behind check-in
counters. If baggage blocks the photoelectric sensor for a timed interval
exceeding set timer limit (adjustable 0-10 seconds), that conveyor plus the
adjacent downstream conveyor shall stop and all related upstream conveyors
shall cascade stop as bags block the photoelectric sensor of each section of
conveyor. At power turns, spiral turns, queue conveyors, and short
conveyors, where applicable, the shut-down operation shall be the same as
identified above. Additionally, an audible and amber visual alarms shall
turn on at the associated Motor Control Panel (MCP) and all associated
audible and amber visual alarms in the field shall also turn on, an amber
JAM light of JAM RESET pushbutton shall be lit on each associated
loading belt control station and local JAM RESET lamp, at the appropriate
point on the System Status OIT located on the front panel of the affected
MCP. The MCP shall have a button for silencing the alarm. Each jam
photoelectric sensor shall be provided with an adjacent amber JAM RESET
illuminated pushbutton in the associated control station. After the jam has
