Calibrate flow sensors
FAN FAULT LED flashes.
CHANGE key must be pressed for at
least 2 seconds to initiate the flow
calibration process.
FAN and POWER LEDs flash to
indicate calibration in progress. Fan is
temporarily stopped as part of the
calibration process. The system will
reset and revert to normal operating
mode when flow calibration is
completed.
Pressing the SELECT key for longer than 1 second when the unit is unlocked will cause the unit to
revert to normal operating mode.
Momentarily pressing the SELECT or CHANGE key when the unit is locked (UNLOCK LED is off)
causes the unit to display the airflow on the bargraph. The display reverts back to the smoke level
reading after a few seconds.
6.2.1 Detector Mode
The ILS-1 has three different modes which can be set to provide different types of coverage.
•
Mode 1
(1 Only): Single Detector
The display shows the detector reading and the unit reports Alert, Action and Fire conditions
when the pre-set thresholds are exceeded.
•
Mode 2
(1 OR 2): Two Detectors working independently (Redundancy)
The display shows the higher of the two detector readings and the unit reports Alert, Action and
Fire conditions when the pre-set thresholds are exceeded on either detector. This mode allows for
continued operation in the event of a problem with one of the detectors.
•
Mode 3
(1 AND 2): Two detectors working together (Double Knock)
The display shows the lower of the two detector readings and the unit reports Alert, Action and
Fire conditions when the pre-set thresholds are exceeded on BOTH detectors.
Note:
Mode 3 is not permitted in a VdS approved installation
The ILS-1 is supplied with a single detector as standard. Mode 2 or 3 operation is dependant upon the
purchase of an optional, second detector. Selection of Modes 2 or 3 with a single detector fitted will
result in a Smoke Detector Fault being reported.
6.3 Setup Notes
The Fan Speed, Flow Limits and Flow Sensitivity need to be set for each installation prior to Flow
Calibration and testing. The following guidelines should assist in the commissioning of the unit.
6.3.1 Fan Speed
The Fan Speed should be set as high as possible to achieve the fastest transport time from the
sampling point to the detector(s), which is especially important for longer pipe lengths and for
installations that must conform to the requirements of EN54-20 (please refer to Section 4.8:
Standard
Pipe Configurations
). However, a balance also needs to be achieved between performance and power
requirements - please refer to current consumption figures in Table 11-1 prior to setting this value.
