B.3.5 Cross Zones
Purpose of Cross Zones
Programming the Cross Zone releasing function can set the control panel to activate a releasing
zone and any output mapped to that releasing zone only after a predetermined sequence of events
occurs.
NOTE: The FACP considers only the primary zone (the first zone in a point’s zone map) to
determine whether conditions have been met for Cross Zone type Z.
A summary of the types of Cross Zones and the conditions for activating a releasing zone:
Table 3:
Type Activates when
No A Cross Zone has not been selected. An alarm from any detector mapped to the
releasing zone activates it.
Yes Two or more initiating devices are in alarm that are mapped to the same releasing
zone.
Zone Two or more initiating devices are in alarm that are mapped to two different primary
zones and that are also mapped to the same releasing zone. Note that the FACP
considers only primary zones to determine whether releasing zone activation should
occur.
Heat At least one smoke detector mapped to a releasing zone is in alarm and at least one
heat detector mapped to the same releasing zone is in alarm.
