FL 128 Multizone System 15.01.2021 37
Note:
The zone numbers are for the zones on the string. When more than 8 zones are used you simply connect
the cores into the appropriate zone numbers (i.e. zone 1+, - can be wire to zone 17 +, - or any other
zone).
Returning Sensor to Use
The detection cable can be wetted and dried any number of times as long as it does not become
contaminated with a substance that irrevocably changes its electrical characteristics. An example may
be vending machine syrup, chemical floor treatments, paint etc. The detection cable will dry out
naturally and the effected part of the cable must be completely dry before the panel can be reset. This
may take 10 minutes to 1 hour or more depending on the environmental conditions and the length of
cable wetted but increased air circulation and warmth will speed up dying time. If a length of cable
seems to take an excessive time to dry out water may be trapped in the retaining clips and these should
be eased to expose the wet area to the air.
Question/Answers
Q. How do I connect more than 1 M8 detection cable assembly together in the same zone?
A. The SOL Junction boxes can be used to connect 2 lengths of detection cable together, so they
act as one zone.
Q. How do I jump between detection areas, which are on the same string?
A. Patch leads with RJ48 connector on both ends can be supplied which can be connected to the
detection cable using SOL junction boxes. Detection zones now consist of a length of detection
cable and a length of leader cable. An Auto-coupler or EOL will still be needed at the end of the
zone.
Q. I have a system fault alarm (open circuit) on a zone where could the fault be.
A. A system fault alarm would be generated (assuming there are no cable breaks/damage) if the
Auto-coupler at the end of a zone has been fitted the wrong way round or the EOL junction Box
has not been fitted. Check the Auto-coupler/EOL Junction Box at the end of the zone in alarm.
Point Sensors (Horizontal and Vertical)
Introduction
Floodline Point Sensors are designed to operate in areas where detection cable/tape could be damaged
or where some damp, minor wetting or spillage is expected or of little concern e.g. plant room,
basement or tunnel. Water must touch the point sensor probes to activate the alarm. Point Sensors are
normally used in conjunction with a powder-coated steel Floodline Guard Plate which gives heavy-duty
physical protection and assists fixing and adjustment. The point sensor can be used singly in one zone or
in-groups with a number of sensors being connected together and acting as one zone.
Dimensions - 71mm high x 44mm wide x 25mm deep.
(when mounted in the Guard Plate) - 110mm high x 102mm wide x 30mm deep (viewed vertically).
