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.
