LED Marquee
Installation/Guide
This guide provides typical installation instructions. Please bear in mind that building codes vary and the
technician installing the LED Marquee is responsible for compliance with any relevant codes.
Installation Overview
1) Determine desired mounting location
2) Determine power source
3) Affix mounting brackets
4) Connect power cable to the Marquee
5) Connect comms from Alert Beacon
6) Test the unit
General Mounting Guidelines
Recommended locations for installing LED Marquees include:
1) Heavily trafficked building corridors
2) Lobbies and points of egress
3) Areas with overly high ambient noise
Install location with a drop ceiling:
The preferred method is to install an electrical outlet in the ceiling, and use a plug-in AC transformer (e.g.
Mouser Part # 507-XT2420, or AllElectronics Part # ACTX-2420). This presents a number of advantages:
Plug-in transformers include a locking screw to prevent accidental unplugging.
Power can be disconnected without needing to turn off the mains; simplifies maintenance (i.e. if power
supply needs to be replaced)
The power supply for an external siren or strobe can be connected to the second outlet, providing for future
expansion.
AC plug-in transformers do not come pre-wired, so it is necessary to obtain crimp-on spade lugs for the
transformer connection, a compatible “Euro-block” style connector (Digi-Key Part # ED2779-ND or
ED1701-ND) for the LED Marquee connection, wire strippers and an appropriate crimp tool.
Install location without a drop ceiling:
This typically requires a standalone step-down transformer. These are often slightly more expensive than
the plug-in type, and are more complicated to install. However, this method is sometimes necessary if there
is no place to install an outlet, or for aesthetic reasons. While a full install procedure for a hardwired
transformer is beyond the scope of this document, the following are some UL-approved models known to
function well with the Alertus LED Marquees:
Foster Transformer, Model 15343
Grainger Item #6WU91 (fits inside a deep double-gang box)
