Notes:
The analogue thresholds for analogue detectors can be changed for both fire and alert. See the installation and commissioning manual for details.
On the S90 3-way analogue unit, either the analogue value or logic inputs can raise alarms. The analogue thresholds can also be changed for fire and
alert on this device. See the installation and commissioning manual for details.
The number of devices with LEDs operated is limited to eight per loop.
If a device has more than one condition active then only the highest level event will be reported although lower level alarms may be present on the
display. For example, if a smoke detector enters an alert condition this will be indicated on the panel. If the device subsequently enters a fire
condition the alert will clear but the alert LED will become steady to indicate the event occurred.
