Honeywell 4219

This module adds up to eight end-of-line resistor supervised zones to compatible control/communicators via the control’s keypad wiring. The 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.
