Enable/Disable Detection Zones
-
Detection Zone #1 is always enabled as a default setting.
Detection Zone #2 may be enabled as required. In the STRIKE ECS Unit Utility window, next to
Detection Zone #2, enable the zone by checking the ’Enable’ box next to it. To disable Detection
Zone #2, uncheck the ’Enable’ box next to it (See Figure 4.10.3c).
Programming Detection Zones with Discharge Zones
-
The STRIKE ECS has two zones of detection
with two discharge zones (actuation circuits). Each detection zone can be mapped to the desired
discharge zone(s) as a means of actuating an Amerex HELIX Fire Suppression System zone. In the
STRIKE ECS Unit Utility window, select the desired discharge zone(s) by choosing from the drop
menu next to each enabled detection zone. Either Discharge Zone 1 or both zones may be selected
for Detection Zone 1. A single discharge
zone, both zones, or no zones may be selected for
Detection Zone 2 when enabled (See Figure 4.10.3c). The ‘Discharge Both Zones’ option may be
used in a situation where simultaneous actuation of both discharge zones is required.
WARNING:
Selecting ’None’ for the discharge zone for Detection Zone 2 (when enabled) is not permitted
by NFPA or UL 864.
