What is the LGR25?
The LGR25 is a BACnet router and a protocol translator for integrating third-party points
into your WebCTRL system.
Room sensors You can wire RS sensors to the LGR25's Rnet port. An Rnet can consist of any of the
following combinations of devices wired in a daisy-chain or star configuration:
• 1 RS Plus, RS Pro, or RS Pro-F
• 1–4 RS Standards
• 1–4 RS Standards, and 1 RS Plus, RS Pro, or RS Pro-F
• Any of the above combinations, plus up to 2 BACviews, but no more than 6 devices
total. See BACviews below.
CAUTIONS
• The LGR25 is a Class 2 device (less than 30 Vac, 100 VA). Take appropriate isolation
measures when mounting it in a control panel where non-Class 2 devices (120 Vac or
greater) are present.
• ALC control modules can share a power supply as long as you:
○ Maintain the same polarity.
○ Use the power supply only for ALC control modules.
To wire for power 1 Make sure the LGR25’s power switch is in the OFF position to prevent it from
powering up before you can verify the correct voltage.
2 Remove power from the power supply.
3 Pull the screw terminal connector from the control module's power terminals labeled
24V ac/dc and Ground.
4 Connect the transformer wires to the screw terminal connector.
5 Apply power to the power supply.
NOTES
• Carefully plan your addressing scheme to avoid duplicating addresses. If third-party
devices are integrated into the system, make sure your addresses do not conflict with
their addresses.
• The MAC and IP addresses are defined in SiteBuilder in the control module's Device
Properties dialog box.
• You can address the LGR25 before or after you wire it for power.
1 If wired for power, turn off the control module's power. The control module reads the
address each time you turn it on.
2 Use the rotary switches to set the address. Set the Tens (10's) switch to the tens digit
of the address, and set the Ones (1's) switch to the ones digit.
EXAMPLE If the control module’s address is 25, point the arrow on the Tens (10's)
switch to 2 and the arrow on the Ones (1's) switch to 5.
To assign a 1 Obtain the IP address, subnet mask, and default gateway address for your router from
custom IP the facility network administrator.
address 2 Set the LGR25's Enhanced Access DIP switch to ON.
3 Set the Default/Assigned DIP switch to Assigned.
4 Turn the control module's power off, then on again.
5 Connect the WebCTRL server to the LGR25's Local Access port. See steps 1 and 2 of
To communicate through the local access port (page 18).

Notification WebCTRL alarms use Notification Class #1. A BACnet alarm's Notification Class defines:
Class #1 • Alarm priority for Alarm, Fault, and Return to Normal states
• Options for BACnet alarm acknowledgement
• Where alarms should be sent (recipients)
NOTE You may need to set up additional Notification Classes if your system will handle
Life Safety alarms or if you need to send certain types of alarms only to an alarm manager
other than WebCTRL.
Calendars Calendars are provided in the module driver for BACnet compatibility only. Use WebCTRL's
Schedules feature instead.
NOTE To set up alarm actions for control module generated alarms, see Setting up alarm
actions in WebCTRL Help.
