[1] The addresses in this table demonstrate the importance of ensuring that the SIGA-REL
occupies six consecutive addresses. The actual addresses in your system may differ.
Programming an AND group
WARNING:
Set the AND group activation number to 2 or greater. An activation
number of 1 will cause the AND group to become an OR group, and any
activation of Alarm_1 or Alarm_2 will activate the release sequence. Check only
Q1 for each device in the list box labeled “Devices in Selected Group.” For Q1,
only a detector in alarm will count as a device activation. If you check Q2, Q3, or
Q4 the release circuit may accidentally activate for maintenance events.
AND groups function as counting groups; matrix groups function as counting
zones. For more information about programming AND groups and matrix groups,
see the 3-SDU Online Help.
Note:
Every device contained in each (SIGA-REL) AND group must include a
rule with an output statement like the one in [ALARM1]. See Figure 18 for the
details.
Note:
For preaction operation, set the activation number to 1. This will cause the
AND group to become an OR group. Any activation of Alarm_1 or Alarm_2 will
then activate the release sequence.
Note:
To comply with NFPA 72, you must program an AND Group with at least
two smoke detectors and a minimum activation count of 2. The smoke detectors
must have their Primary and Alternate Verification properties set to None (verified
smoke detectors are not allowed).
Writing rules for the SIGA-REL
To write the rules:
1. In the Rules Editor, write the rules shown in Figure 18.
2. Compile the rules and run the required conversions.
3. Download the new information.
4.
See “System testing” on page 52 before you test your system.
