Where “<a>” is the number of the indicating circuit output.
First Or Second Alarm
Each output programmed as INDICATING can be designated to operate on first or second alarm. First alarm is identified as
NORMAL, second alarm is identified as 2ND ALARM. Any outputs programmed as INDICATING & NORMAL will operate
when the zone they are mapped to is activated. Any output programmed as INDICATING & 2
ND
ALARM will operate when two
or more zones mapped to it are activated. These outputs will operate in a continuous pattern even after the release circuit activates.
Zones programmed as MANUAL RELEASE will activate outputs programmed as SECOND ALARM, even if the MANUAL
RELEASE zone is the first alarm zone activated. SECOND ALARM is intended to be used as a pre-discharge signal for cross
zone applications. Refer to page 60 for a complete description of first and second alarm requirements and operation.
SET Press the SET button to set the description displayed.
SELECT Press the SELECT button to scroll between NORMAL & 2ND ALARM
FUNCTION Press the FUNCTION button to skip to the next function.
After selecting all four outputs or pressing FUNCTION, the following will be displayed if any outputs have been described as RELEASING:
Where “<a>” is the number of the releasing circuit output.
Normal/Cross-Zoning
Each releasing circuit can be set up for the normal or cross zoned operation. In NORMAL operation, any alarm initiating zone
including LOW AIR ALARM mapped to a releasing output must be in alarm before the output is activated. In cross zoned
operation ALL initiating zones mapped to the releasing circuit must be in alarm before the output is activated. An initiating zone
previously described as “MANUAL RELEASE” will override the cross zoning feature.
SET Press the SET button to set the operation displayed.
SELECT Press the SELECT button to toggle between NORMAL and CROSS ZONED.
FUNCTION Press the FUNCTION button to skip to the next function.
After selecting normal or cross zone operation the next function will be displayed as follows:

An output programmed as INDICATING & 2nd ALARM that has only one initiating zone mapped to it will never operate.
Likewise, if multiple zones are mapped to that ouput and only one zone activates, that output will not operate until another
zone mapped to it activates.
After selecting an output as INDICATING, a display similar to the following will appear:
