PART 2 MATERIALS AND COMPONENTS
2.01 LOW VOLTAGE SWITCHING CONTROL PANELS
1)
Description
a) Lighting Control Panels shall be UL listed and consist of the following:
i) Enclosure/Tub: NEMA 1 sized according to project requirements.
Strand Lighting Specifications
ii)
Cover: Surface or Flush as required, hinged, lockable configuration. (other custom covers available as
project specifications require)
iii) Interior: Barrier for separation of high voltage (class 1) and low voltage (class 2) wiring. Intelligence
boards, power supply, control relays and contactors.
2)
Features
a)
Relays shall be individual latching relays with 20 Amp load contacts for ballast (including HID, magnetic or
electronic type ballasts), tungsten, general use and rated for 200,000 operations at full load. Provide isolated
auxiliary contacts for pilot light switching. Relays shall use quick connectors and be individually replaceable to
facilitate ease of use.
b)
The Strand Lighting relay control panel shall be able to house multi-pole contactors for control of multi-circuit
or multi-phase loads. Contactors shall be rated for 20 Amps tungsten, 30 Amps for ballast or general use and
shall be compact, rail mount style for easy installation and use.
c)
Lighting control panels shall provide a stagger up delay, override push buttons, pilot light outputs, and LED
status light indicators for each relay.
d)
Standard switch inputs shall have a one-for-one default assignment to relays. Master inputs shall be
unassigned.
e)
Switch inputs shall be self-configuring and shall not require programming to accept momentary on/
momentary off, push button (cycling), maintained or 3 to 24VDC signal. Using any of these switch types shall
not sacrifice the number of switch inputs available. Switch inputs shall allow switch wiring distances of up to
5000 feet on 20 gauge wire.
f)
All Relay racks shall support a standard DMX512 digital control input. Each relay in the panel is controlled by
one DMX control address. A channel level greater than 50% will turn the relay on and a level below 50% will
turn the relay off. Local override is accommodated via the low voltage switch terminals on the relay driver
cards. Direct wired override switches connected to the driver cards will always have priority to control the
relay ON/OFF regardless of the state of the DMX control signal.
g)
Relays that are controlled by both a DMX channel and a group switch will operate in accordance with a
predefined override priority scheme. Relays that are controlled by both DMX and either a group switch or
individual switch will respond to control based on the following override priority system:
DMX level ≧75% = relay ON, ignore override
DMX level <75% but >50% = relay ON, accept override
DMX level >25% but ≦50% = relay OFF, accept override
DMX level ≦25% but > 0 = relay OFF, ignore override
DMX level 0 = DMX NULL, accept override
h)
A ShowNet Ethernet Network control interface shall also be available providing similar features to the DMX
control input. Systems not offering these features shall not be acceptable.
2.02 LOW VOLTAGE SWITCHING RELAY PACKS
1)
Description
a) Automatic relay packs shall be UL listed and consist of the following:
i) Enclosure: NEMA 1 rated with ½” conduit nipple for connection to junction boxes and concentric knock
out pattern for wire entry into low voltage section.
ii)
Cover: Screw cover for low voltage wiring section.
iii) Interior: An integral controller board with all electronics, power supply and load controller relays in a
sealed compartment. A low voltage compartment with terminals for connection of switches, occupancy
sensors, network wiring and other control components.
3)
Features
a)
Page 1
Relay pack shall provide a stagger up delay, 24VDC pilot output voltage, and LED status indicator for each
relay. Each relay shall have a default assigned switch input that self configures to accept momentary on/
momentary off, push button (cycling), maintained or 3 to 24VDC switching signals. Multiple switch inputs may
be wired together for simultaneous operation. Switch inputs can support wiring distances up to 5000 feet
using 20 gauge wire.
