RadioRAR 2 Wall-mount Designer keypads
* IR codes are transmitted from an IR remote to the IR receiver on a keypad while a button on the
remote is being held down. Timeouts may occur when seven seconds of continuous IR code
transmission has taken place. Therefore, it is important to transmit the most significant bit of the IR
code first.

RadioRAR 2 keypads can accept IR into the front or back of the unit, leading to the potential to have
both electric light and power conductors and Class 2 circuit conductors in the same wallbox.
Solution...
The 2008 National Electrical CodeR (NECR) Article 725.136 (D) provides the specific rules governing
Class 2 conductors and electric light and power conductors within the same wallbox. It states
that electric light and power conductors may be allowed in the same enclosure as Class 2 circuit
conductors, provided they are both introduced for connection to the same equipment, and if one of
the following requirements is also met:
1. The electric light and power conductors are routed to maintain a minimum of 1/4 in (6 mm) of
separation from the Class 2 circuit conductors, or:
2. The circuit conductors operate at 150 V
or less, and meet the following requirement:
Class 2 circuits are installed using types CL3, CL3R, CL3P or permitted substitute cables and the
cable conductors extending beyond the jacket are separated by a minimum of 1/4 in (6 mm), or
by a nonconductive sleeve / barrier, from all other conductors.
Understand though...
The NECR is a document subject to interpretation. Your local city, county, municipality or state
authorities have the final authority to approve or disapprove any installation. They must always be
consulted for verification of the code, and the manner in which it will be applied in your area, prior to
installation.
