The Honeywell Home Intrusion 4120TR is a trigger cable designed for use with the 4120 series intrusion detection and communication equipment. This cable provides the physical trigger connection needed to link compatible control panels or communicators to external devices, enabling reliable signal transmission in security system installations. It is sold as a single unit and is typically installed by licensed security system technicians or low-voltage electricians working on commercial or residential intrusion detection systems.
The 4120TR is intended for use with 4120 series communication and intrusion control equipment. It is suited for installations where a dedicated trigger interface cable is required to complete the wiring between a communicator or control panel and an auxiliary device. This accessory supports clean, direct connections in structured security system wiring layouts.
Designed as an OEM-style trigger cable accessory for use with 4120 series intrusion detection and communication equipment.
Installation should be performed by a licensed security technician or low-voltage electrician in accordance with applicable local codes and NEC guidelines for low-voltage wiring. Power down the control panel or communicator before connecting or disconnecting any cables. Ensure all connections are fully seated and secured before restoring power. Do not route trigger cables in close proximity to high-voltage wiring to avoid interference.
