Chapter 2: Front panel programming
Vigilant VS1 and VS2 Technical Reference Manual 85
Programming fast groups for sounder bases
UL/ULC require alarms to sound within 10 seconds after a fire is detected. This can be
difficult to achieve in large systems with hundreds of sounders, unless the sounders
are properly grouped.
To address this requirement, Vigilant VS1 and VS2 systems provide 25 high priority
correlation groups per loop that can activate all sounders simultaneously. These are:
• For panels with one loop only, the fast correlation groups are Groups 001 to 025
• For panels with two loops, the fast correlation groups are
Loop 1: groups 001 to 025
Loop 2: groups 001 to 025 or 101 to 125 (user configurable).
In dual loop systems, you can combine devices from loop 1 and 2 in correlation
groups 001 to 025, or you can separate them and use groups 101 to 125 for loop 2.
See “Changing loop configuration options” on page 78.
For best performance use the fast correlation groups for bulk activations, such as
entire floors and save the slower correlation groups for small sets of activations such
as individual suites or hotel rooms.
Note: Be sure the Follow option for devices to be added is None, Alarm, Alarm and
Verify, or Alarm and Prealarm. Be sure the Follow option is not set to Head or Riser. If
you need to run a report to check the Follow option, see “Device Details report” on
page 175. If you need to change the Follow option, see “Adding and removing devices
from programmed systems” on page 67.
