Figure 9. Resistance bands for FSL detectors
Note that an installer can wire resistors to the contacts of a closed circuit loop
detector with a Fault (or Trouble) output in order to use FSL signalling (see
Fully Supervised Loop Connections
in the i-on160EX Installer Guide). The
detector must signal masking by closing both the Alarm and Fault contacts
together.
When masking is enabled the alarm response depends on whether the system
is set or unset, and which resistance range the detector is signalling with.
When the system is
unset
:
Detector
output
Response
Mask
(9k1)
The control unit treats a masking event as a fault, activates any
outputs programmed as General Fault or Masking, and generates
an Alert on the keypads.
A user can reset the system once the masking is cleared.
Fault
(4k4)
The control unit treats a masking event as a fault, activates any
outputs programmed as General Fault, and generates an Alert on
the keypads.
On a Security Grade 3 system the Installer must reset the Alert.
