SIGMASYS monitored line

12.3.1

Spur

Up to 64 address can be assigned for connected detectors and devices (transponders, indica-
tor panel, zone operating panel) as a spur on a SIGMASYS monitored line.
According to the guidelines (VdS 2095), however, there should only be max. 32 auto-
matic detectors in a detector zone (fire section) or 10 non-automatic fire detectors connected
to a spur.
12.3.2

Loop

A loop is created by joining two monitored lines (spurs), 1 with 5, 2 with 6, 3 with 7 and
4 with 8.
The element sequence is always counted from the lowest to the highest monitored line. Up to
128 SIGMASYS elements can be connected to a loop. Advantages of a loop compared to a

spur:

•
Protection against failures. All elements continue to work even in the event of a failure,
e. g. wire breakage.
•
Connection of control facilities system-wide.
•
A monitoring surface of up to 6000 m

SIGMALOOP detector algorithm

The sensitivity of SIGMAPLUS smoke detectors can be set as follows in SIGMASYS C, M,
and L control and operating panels and M modules in V3.1 and later by means of parameteri-
zation with PLAN D100 V5.1.
