LINEAR LOCKING CONTROL PANELS
2.3.1
Linear Panels
Provide linear panels as indicated and as specified to control groups of
designated electric-operated locking devices. Linear locking control
panels shall be manufactured and installed with same type materials and
process as graphic locking control panels and shall be identical except
that graphic floor plan display is not required.
2.4
WIRING REQUIREMENTS
2.4.1
Power Wiring
Provide No. 14 THWN or XHHW conductors for solenoid-operated lock sets
operating at 120 volts. Connect solenoid-operated lock sets operating at
24 V ac or dc with No. 16 MTW conductors.
2.4.2
Control Wiring
Wiring for status indicators shall be class one signaling circuits as
defined by Article 725 NFPA 70. Conductors shall be No. 16 MTW and shall
be installed in common conduit and equipment enclosures with other
conductors for locking devices within limitations defined by Article 725-15
NFPA 70.
2.4.3
Wiring Materials
Wiring systems shall use solid copper conductors. Stranded conductors
shall be acceptable only where all terminations can be made to screw type
lug. Where stranded conductors are used, all terminations shall be made
with crimp type lug, correctly sized for termination, and applied to
conductor with crimping tool intended for use with lug used.
2.4.4
Color-code wiring systems, providing each conductor for individual lock
sets and operating mechanisms with a distinctive color. White conductor
shall be used only for neutral conductors, and green shall be used only for
grounding conductors.
2.5
DISCRETE ELECTRONIC LOCKING CONTROL SYSTEM
2.5.1
Logic Units
Discrete electronic locking control system shall consist of logic units in
the form of printed circuit boards, relay terminal equipment, and
associated hardware and wiring. Control system shall accept input control
information from and send output status information to graphic and linear
type locking control panels.
2.5.2
Printed Circuit Boards
Logic units shall be printed circuit boards provided with circuitry
necessary to perform the functions as specified. Logic circuit boards
shall be mounted in a card cage frame, arranged to allow front and back
access. Provide wiring connections to printed circuit boards capable of
being connected to allow field replacement of printed circuit board with no
disconnection or desoldering of wiring. Card cage frame shall be rack
