6.5.1Specify Longest Cable Length
You may specify the length of the longest cable connected to either of the
Select the longer cable length installed on either zone. For example, if Zone 1 has 2000 ft. (609.6m) of cable and Zone 2 has 3500 ft. (1066.8m), select
The chosen setting applies to both zones and is correlated to the
5mA = 0 ft. (0m)
19mA = 4000 ft. (1219.2m)

•Press Enter ↵ .
6.5.2Define Relays as Normally Open or Normally Closed
All four digital alarm outputs may be set up as Normally Open (NO) or Normally Closed (NC). The default setting is NO (Normally Open). The chosen setting applies to all cable fault/contamination and leak relays for both zones.
To change the normal state:
•From the Normally Open / Closed screen, below right, use the arrows ↑↓ to choose NO (Normally Open) or NC (Normally Closed).
•For a

6.5.3Define Alarms as Latched or Unlatched
All four digital alarm outputs may be set up as Latched (Y) or Unlatched (N). When configured as Latched, alarms must be manually reset by an operator after they are cleared, as described in 6.9 - Reset Latched Alarms. The default setting is Latched (Y). The chosen set- ting applies to cable fault and leak relays for both zones.
