the normal range. It is advisable to set this parameter on for such the alarm loops which involve detec-
tors producing high voltage ripples in the alarm loop.
The Related Addressable Detectors parameters relates an alarm loop of the Type 14 (the threshold
addressable alarm loop) with the addresses of the already installed into the loop addressable detectors
or call points – see Fire Threshold Addressable Alarm Loop (Type 14) section of this Manual. If the ad-
dressable zone of an addressable detector or call point is not related to an alarm loop, this zone doesn’t
take part in generating of a generalized loop and is not affected by loop arming/disarming commands.
Alarm Loop Types
The main alarm loop configuration parameter which defines the way the controller considers the condi-
tions of the alarm loop is the Loop Type. The Signal-10 supports 10 different types of alarm loops.
Table 2 shows how the current resistance values of alarm loops are considered by the Signal-10 device
to be different loop statuses depending on the current type of the alarm loop.
