Installation
Environmental requirements
Care must be taken to observe these considerations when selecting a location for the sign.
• These signs are for indoor use only and should not be continuously exposed to direct sunlight.
• These signs should only be used in an environment where the temperature is between 0 and 50
degrees Celsius (32° to 122° F.)
• These signs should only be used in an environment where the humidity (non-condensing) does not
exceed 95%.
• For installation, there must be at least 1” (2.5 cm) clearance on each end of the case and at least 2”
(5.1 cm) clearance above the case.
Reducing electrical noise
These procedures are recommended to decrease the amount of electrical emissions and noise with the
AlphaPremiere™ 9000 signs:
•A sign should be connected to its own branch circuit.
• The input power source should be protected by a circuit breaker rated at no more than 20 amperes,
with no more than 4 signs connected together through a single circuit breaker.
• Incoming power to a sign should be routed on a path separate from a sign’s serial communication
wires. Do NOT run the power and communication wires in the same conduit.
•Where power and serial communications wires must cross, the intersection should be perpendicular.
• All serial communication wires should be shielded. The shield should only be connected to ground at
the RS485 converter box.
Checking speaker volume
Before mounting the sign, you should check the volume setting of the speakers, as described in “Speaker
volume control” on page 9.
Wall mounting instructions
Guidelines
Wall-mounting brackets are provided with the sign. Fasteners are supplied to attach the brackets to the
sign. However, fasteners to attach the sign to a wall are not supplied.
The specific type of fastener needed depends on the physical characteristics of the wall (e.g., concrete,
brick, wood) to which the sign is being mounted. Do NOT install directly to drywall, plasterboard, or other fragile
supports.
• Fasteners for wall-mounting brackets must be appropriate for the type of wall to which the sign will
be mounted.
• Each one of the fasteners must be capable of supporting four (4) times the weight of the sign.
•A sign must be attached to a wall (or to a wall-mounted support system) capable of bearing at least
four (4) times the weight of the sign.
Directions
1. Disconnect power from the sign.
2. Remove the two screws from each end cap.
NOTE: There are speaker wires behind the right end cap, so be careful to keep one hand on the end
cap—continuing to hold it in place—after removing the screws. Pull the end caps away
slowly, so you don’t accidentally snag the wiring or damage other components near the cap.
