NOTES: Observe the following points.
•  To be installed and used in accordance with appropriate electrical codes and regulations.
•  This product should be installed by a qualified electrician.
PREPARING AND CONNECTING WIRES
Strip the ends of the wires approximately 1/4 in (6 mm). Use care to avoid nicking the conductors. Twist together 
the ends of the wires that share a connection. Apply solder only to the ends of the twisted wires. Avoid tinning too 
far up the wires or the end becomes brittle.

NOTE:  This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of 
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential 
installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in 
accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that 
interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television 
reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the 
interference by one or more of the following measures:
  •  Reorient or relocate the receiving antenna
  •  Increase the separation between the equipment and receiver
  •  Connect the equipment into an outlet on a circuit different from that to which the receiver is connected
  •  Consult the dealer or an experienced radio/TV technician for help
Industry Canada (IC) Compliance Statement
This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two 
conditions: (1) this device may not cause interference and (2) this device must accept any interference, including interference 
that may cause undesired operation of the device.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) 
gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type 
and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for 
successful communication.
This radio transmitter, IC: 5683C-CWD7191, has been approved by Industry Canada to operate with the antenna types listed 
below with the maximum permissible gain and required antenna impedance for each antenna type indicated.  Antenna types not 
included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this 
device.
Antenna Type: Dipole, Maximum permissible antenna gain: 2.5 dBi, Impedance: 50 Ohms

DESCRIPTION
The Crestron Green Light
® GLA-EXPEX is a 2-way RF wireless expander designed to extend 
the range of Crestron® lighting control products in an infiNET EX
® network. The GLA-EXPEX 
is optimized for installation in building systems where a hard-wired expander is necessary. 
Suitable for installation in plenum airspace, the GLA-EXPEX is built with a metal enclosure 
that mounts directly to a 4-inch square electrical box. Additionally, the GLA-EXPEX accepts a 
range of line voltages from 100 to 277 volts, which makes it easy to install in almost any 
location. Up to five GLA-EXPEXs can be deployed in any infiNET EX network.
infiNET EX
Ultra-reliable infiNET EX wireless technology provides steadfast 2-way RF communications 
throughout a residential or commercial structure without the need for physical control wiring. 
Employing a 2.4 GHz mesh network topology, each infiNET EX device functions as an 
expander, passing command signals through to every other infiNET EX device within range 
(approximately 150 feet or 46 meters indoors), ensuring that every command reaches its 
intended destination without disruption.*
The GLA-EXPEX communicates with a Crestron control system via an infiNET EX wireless 
gateway (CEN-RFGW-EX, DIN-AP3MEX, or MC3—all sold separately). Up to 100 infiNET 
EX devices, including Cameo® wireless keypads and in-wall switches (sold separately), may 
coexist on a single wireless network, and every device that is added to the network 
effectively increases the range and stability of the entire network by providing multiple 
redundant signal paths.* Built-in dynamic frequency allocation continuously monitors RF 
conditions and automatically selects the clearest channel to prevent interference from 
neighboring networks, cordless phones, and microwaves.

Specifications for the GLA-EXPEX are listed in the following table.

DEVICE STATUS
The LED on the front of the GLA-EXPEX communicates the operational status of the 
device.
The red LED lights when the GLA-EXPEX is not acquired by a gateway or not 
communicating with a gateway.
The red LED also lights while the GLA-EXPEX powers up. 
The green LED lights when the unit is successfully acquired and communicating with a 
gateway.
WIRELESS COMMUNICATIONS
The device connects to the Crestron network via the infiNET EX communications protocol. 
Use the procedures outlined below to join or leave an infiNET EX network and to verify 
communications between the device and the control system.
Joining an infiNET EX Network
Before a device can be used in a lighting system, it must first join an infiNET EX network by 
being acquired by an infiNET EX gateway.
NOTE:  A device can be acquired by only one gateway.
  1.  Put the infiNET EX gateway into  mode from the unit itself or from Crestron Acquire 
Toolbox™, as described in its manual at www.crestron.com/manuals.
NOTE:  In an environment where multiple gateways are installed, only one gateway 
should be in  mode at any time.Acquire 
  2.  Place the device into  mode.Acquire 
  a. Tap the  button three times then press and hold it down STATUS 
(tap-tap-tap-press+hold) until the LED on the device blinks once from amber to red 
(this can take up to 10 seconds).  
  b. Release the button to start the acquire process. The GLA-EXPEX LED starts to 
slowly blink, alternating between red and green to show that the device is actively 
scanning the infiNET EX network.
  •  The device is acquired when the red LED lights for 5 seconds.
  •  The LED starts to blink alternately between amber and red to indicate that the 
device was not successfully acquired. Press the   button to STATUS
acknowledge failure. Ensure gateway is in   mode and within range Acquire
before attempting the acquire process again.
  3.  Once all devices have been acquired, take the gateway out of  mode. Refer to Acquire 
the gateway’s operations guide, as described in its manual.
Leaving an infiNET EX Network
To leave an infiNET EX network put the device into  mode, as described in “Joining Acquire 
an infiNET EX Network” above, when no gateway is in  mode.Acquire 
Verifying Communications Status
To check the communications status of the device tap the  button three times then STATUS 
press and hold it down (tap-tap-tap-press+hold) for less than 2 seconds. The LED indicates 
the communication status. Refer to the following table for details.

Important Notes
Read before wiring and installation.
CAUTION:  To be installed with 14 AWG (2.5 mm²) wire that complies with local electrical 
codes. 
WIRING
WARNING:  Turn off power to the GLA-EXPEX before wiring. Wiring with the power on 
can result in serious personal injury and damage to the device.
