Panel Serial Number in Serial 3 Messages 

This update allows you to enable Serial 3 messages to include the panel serial number. If enabled, the panel family and corresponding serial number appear at the end of each Serial 3 message, allowing the monitoring center to identify the correct system if two panels unintentionally use the same account numbers. 

This update requires one of the following:

• SCS-VR Virtual Receiver
• SCS-1R Network Enabled Receiver with the SCS-150 Main Processor Card at firmware Version 108 (9/23/25). 

To enable Serial 3 messages to include the XT75 panel serial number, complete the following steps:

1. At the keypad, enter 6653 (PROG) and select CMD to enter the programming menu.
2. At SYSTEM REPORTS, go to SYSTEM INFORMATION.
3. Select YES to enable Serial 3 messages to include the panel serial number. The default option is set to NO.
4. Go to STOP to save programming. 

To program Serial 3 messages to include the panel serial number on Dealer Admin, refer to TU-1484. 

Holdup Zone Type 

A new zone type called Holdup has been added to Zone Information. Holdup zones operate as silent panics and do not trigger bell actions, or audible or visual alerts on the keypad. 

To program a zone type as Holdup at the keypad, complete the following steps:

1. At the keypad, enter 6653 (PROG) and press CMD to enter the Programmer menu.
2. At ZONE INFORMATION, go to ZONE TYPE.
3. Press CMD to view additional zone types until you see HU (Holdup) as an option.
4. Select HU (Holdup) as the zone type, then press CMD.
5. Configure additional Zone Information options as needed.
6. Go to STOP to save programming. 

To program a zone type as Holdup in Dealer Admin, refer to TU-1484. 

Z-Wave Improvements 

Previously the 738Z+ Z-Wave Plus Interface Module would remain in an action for longer than desired. This update allows the 738Z+ to return to its default state for quicker adding, editing, and deleting of Z-Wave devices and actions.
