8 Zone Wired Expansion Module

The Honeywell 4219 is a wired zone expansion module that provides up to (8) additional hardwired zones of protection for a Honeywell VISTA-15P, VISTA-20P or VISTA-21iP alarm control panel. The 4219 zone expansion module is ideal for existing security systems when you need to add additional hardwired alarm devices but have no more available zones.

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 class B zone inputs to an ECP bus addressable system, each with 1K end-of-line resistor
• Class B loops provide a broad, 300 ohm tolerance
• Supervised for open, shorted and normal circuit conditions
