4219 - Honeywell Home Hardwired 8-Zone Expansion Alarm Module
Honeywell Home 4219 Product Description:
The Honeywell 4219 is a expander module adds up to eight normally closed or eight end-of-line resistor supervised zones to compatible control/communicators via the control's keypad wiring. The 4219 is recommended for commercial systems when deploying conventional detectors in an ECP zone expandable system.
The 4219 wired expander is ideal for expanding existing hardwired installations without needing to change out the existing alarm control panel. The 4219 is a great addition to any compatible Honeywell wired security system or Honeywell hybrid security system. It is housed in a white plastic case for wall mounting and can be mounted in a universal alarm can. If the 4219 is remotely mounted, there are provisions that tamper protect the unit so that it cannot be disconnected from the control panel wiring without detection by the Honeywell security system.
The 4219 expansion module may be mounted within the control's cabinet (if room permits), or remotely. If mounted remotely, there are provisions to tamper protect the unit. Communication to the module is supervised so that it cannot be disconnected from the keypad wiring without detection by the control. If the wiring is cut, a tamper alarm or signal will result, to indicate that this device (and possibly other similarly connected devices) has become inoperative.
Product Features:
- Can be located anywhere along the four-wire addressable ECP bus
- Simple DIP switch addressing to select range of zone numbers
- Adds up to eight (8) class B zone wired inputs to an ECP bus addressable system, each with 1K end-of-line resistors
- Comfortably fits inside the controls cabinet
- Class B loops provide a broad, 300 ohm tolerance
- Supervised for open, shorted and normal circuit conditions
- UL-Listed for commercial burglary applications
- Backed by Honeywell's 2-year limited manufacturer's warranty
IMPORTANT: Some carbon monoxide detectors may not be compatible with the Honeywell 4219 hardwire zone expanders. When using carbon monoxide detectors in systems that support the 4219 zone expanders, install the detectors only on the basic hardwire zones of the system control panel, and NOT on the zone expanders.

Incredible Tech Support, March 16, 2026

I recently added the Honeywell 4219 Wired Zone Expander to my VISTA-20P security system, and it worked flawlessly. The installation was straightforward with the help of Sal at GeoArm, and the added zones gave me the flexibility I needed to expand my system without replacing my existing setup. The module integrates perfectly with the VISTA-20P and performs exactly as expected.
What really made the experience stand out was the incredible support from the GeoArm team. They guided me through the setup and installation process step by step, making everything simple and stress-free. Best of all, since I purchased the 4219 from them, and have their monitoring services, they provided this assistance at no additional cost.
It?s rare to find that level of customer service these days. Between the quality of the product and GeoArm?s outstanding support, I couldn?t be happier. Highly recommended!
