5424 DUST DETECTOR 5520 WATER ALARM

Cet appareil est conçu pour détecter les particules fines issues de la combustion.
Caractéristiques d’utilisation et d’installation
Signalisation de début de combustion en tout genre. L’absence de contraintes de câblage permet un positionnement correct, ce qui est fondamental pour le bon fonctionnement de cet appareil ; ce dernier s’installe au point le plus haut du plafond, jusqu’à un maximum de 3 m dans des locaux 6×6 m ou équivalents.
5520 Généralités
Cet appareil est conçu pour détecter la présence d’eau ou de liquide de tout genre

Fine particle detector
Flood probe
5424 General
This device is designed to detect fine particles from combustion.
Usage and installation characteristics
Indication of the start of combustion of all kinds. The absence of cabling constraints allows correct positioning, which is fundamental for the proper functioning of this device; the latter is installed at the highest point of the ceiling, up to a maximum of 3 m in rooms 6 × 6 m or equivalent.
5520 General
This device is designed to detect the presence of water or liquids of any kind.
Use and Installation
Flood and / or water or liquid level signaling. The device works connected to Sensor HT code 5515.

5424 power supply
9V alkaline battery type GP1604A or equivalent, allowing an autonomy of about two years with normal use (autonomy decreases significantly in the event of frequent alarms).
Radio transmission
Dual frequency simultaneous DualBand compliant with EU standards. Range adequate for use.
Control and test
Once triggered, the alarm lasts as long as there is smoke in the closed room (a few minutes); to silence the alarm, you must blow a large amount of clean air into the detector.
5424 Operation
This device consists of an infrared photo optical detector contained in a dark room: any fumes reduce the infrared signal until the alarm is triggered.
Attention:
cooking fumes, concentrated steam and other similar particles can set off nuisance alarms. Dust Detector checks the operating state (supervision) and, if necessary, the low battery state every 40 minutes: the control unit highlights these signals during an arming and / or disarming. .
5520 Operation
This device is composed of a body which contains two electronic circuits made of anti-oxidant materials connected to two terminals. Install the device on the wall, with the metal plates facing down, at the desired height for signaling the liquid level. Connect to Sensor HT, which will of course be placed higher up, using the corresponding terminals
