FL 128 Multizone System 15.01.2021 39
A diagram of the connection details for the point sensors is presented in Appendix E.
Once the point sensor, or last sensor in a string has been connected to the leader cable the 1M
“sleeper” resistor, from the zone input terminals in the control panel, should be fitted to the output
terminals of the point sensor.
Returning Sensor to Use
Point sensors can be wetted and dried any number of times and require no attention after activation
unless the whole unit is immersed. In the event of immersion prompt and thorough drying out will allow
immediate return to normal operating status.
Flexi –Pad Sensor
Introduction
The Floodline Flexi- Pad Sensors have been specifically designed for laying in narrow voids (too small for
point sensors),or wrapped around pipes at valves or joints where leaks are more likely to occur. The
flexi- pad sensor can be used singly in one zone or in groups with a number of sensors being connected
together and acting as one zone.
The flexi-pad sensors are made of a tough, flexible plastic sheet 400mm x 300mm x 1mm. A removable
fabric cover assists absorption and protects the sensor surface.
Fixing
The sensor can be laid on any flat surface or tie wraps can be used to loosely hold the sensor around a
pipe etc.
Connecting to the Floodline Panel
The Flexi-pad sensor/s are connected to the zone input terminals of the Floodline control panel via 2
core (minimum) leader cable. The minimum specification of the leader cable from the panel to the
point sensor is standard PVC/PVC 7/0.2mm multi-core alarm/comms type cable or similar. LSF or other
light cables can be substituted if required. A zone can consist of a single flex-pad sensor or any number
of sensors connected as a “string” or “daisy-chain”. Input and output terminals are provided in each
point sensor to allow for this purpose.
A diagram of the connection details for the flexi-pad sensors is presented in Appendix F.
Once the flex- pad sensor, or last sensor in a string has been connected to the leader cable the 1M
“sleeper” resistor, from the zone input terminals in the control panel, should be fitted to the output
terminals of the point sensor.
