Zone Doubling

This feature provides two hardwired normally closed zones for each standard hardwired zone connected to the control’s terminals (but does not increase the total number of zones supported by the control). If enabled (Zone Programming mode, “Hardwire Type” prompt, option “3”), hardwire zones are automatically paired as shown in the table. Connect as shown (resistors provided).

• Do not use zone doubling for fire zones.
