Input-to-Output Circuit Mapping and Cross-Zone Operation
A.1.2 Mapping Input Zones to Release Circuits for Cross Zone
Using the OUTPUT CIRCUITS menus, this fire panel will allow you to assign a release circuit type
of operation to any two of the four output circuits. Up to two releasing circuits (or hazards), called
RELEASE 1 and RELEASE 2, may be created. Input zones may be assigned in various ways to
activate either one or both of the release circuits. The fire panel treats RELEASE 1 and RELEASE
2 functions independently from each other, although they may share input circuits for activation.
Cross-zoning is set up in the CROSS INPUT ZONES menus, where you can create up to three
groups of input zones for each release circuit. When cross zone groups have been set up, the
OUTPUT CIRCUIT MAP associated with the input zones will automatically show YES for release
output circuits. This extremely flexible cross-zone with grouping capability is used in the
following examples.
Example 3: A single hazard, cross-zoned application using two smoke detector input zones and
one releasing output circuit. Input Zones 1 and 2 are cross-zoned to activate output circuit 2, which
is programmed as a RELEASE 1.
•
Output Circuit 1 is programmed as alarm NAC using the OUTPUT CIRCUITS menus.
•
Output Circuit 2 is programmed as Release Circuit 1 using the OUTPUT CIRCUITS menus.
•
Output Circuit 3 is programmed as alarm NAC using the OUTPUT CIRCUITS menus
•
Output Circuit 4 is programmed as supervisory NAC using the OUTPUT CIRCUITS menus.
•
Either of smoke detector Input Zones 1 or 2 will directly activate Output Circuit 1 (Alarm
NAC).
•
Smoke detector Input Zone 2 will also directly activate Output Circuit 3 (Alarm NAC) but
not Output Circuits 2 or 4.
•
Smoke detector Input Zones 1 and 2 are cross-zoned (both must be in alarm) to activate
Output Circuit 2 (Release 1) but not Output Circuit 4.
