NEW! Honeywell 4219 Ademco Wired 8-Zone Expander Modules Compatible Control
Description:
The 4219 expander modules add up to eight normally closed or eight end-of-line resistor supervised zones to compatible controls/communicators VISTA-15P, VISTA-20P, and VISTA-21iP.
The 4219 expander modules add up to eight normally closed or eight end-of-line resistor supervised zones to compatible controls/communicators VISTA-15P, VISTA-20P, and VISTA-21iP. Modules 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 modules 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 the device (and possibly other similarly connected devices) has become inoperative.
