Time to report fire alarms on the backbone interface within 2 seconds
Response time to report a fire alarm.
•
From the moment a detector enters the alarm state, or a manual call
point is activated, to the activation of the common fire relay.
within 3 seconds
Time to recover from a single short circuit on a loop-line.
•
For a single short circuit this means to isolate the short circuit such that
no loop units are lost.
within 120 seconds
Start-up time for the safety function after cold start (external power on) 60 seconds
Time to enter fault condition after a fault has occurred within 100 seconds
Accumulated probability of dangerous failure on demand of the safety
function (PFDavg)
Less than 0.01
NOTE!
A warning will be displayed on the menu screen until the logic solver in the system
is up and running, which is the first minute after the system has been powered up.
Hint!
For detailed requirements regarding system modules and loop units, refer to the data
sheets.
1) Max 10 CS-Loop M modules can be installed in a FDS using the CS-Safety M module and maximized loops (150 units).
2) See "EX Calculator", revision 4 or later
3) In the case of explosion group IIB you may ignore the detector's internal capacitance
