DUONET & QUADNET EN54 Two & Four Loop Addressable Fire Alarm Systems

DUONET & QUADNET EN54 Two & Four Loop Addressable Fire Alarm Systems

The Duonet & Quadnet intelligent fire alarm systems offer both cost-effective and reliable solutions for a wide variety of fire detection applications. The innovative technology built into the Duonet and Quadnet panels is designed to significantly reduce false alarms.

The Duonet & Quadnet systems can both support up to 200 Multipoint ASD combined detector/sounders on a single loop. Integrity of the system is maintained by way of a built-in isolator incorporated within every device. System intelligence has been harnessed in such a way that equipment used is very easy to install, commission and maintain.

The system has been designed to high specification and quality standards, and complies with the EN54 – 2 and EN54 – 4 standards and EU directives.

Powerful software gives the capacity of up to 4 loops for the Quadnet and 2 loops for the Duonet panel, making addressable Multipoint ASD detector technology available to customers with systems up to 800 devices.

Using the Multipoint ASD detector as part of the Duonet & Quadnet systems means that when a detector is wired to the system, a sounder and strobe can also be connected without extra installation time or cost. This greatly reduces the number of points that need to be installed and the time it takes to install. As the Multipoint ASD offers 6 different modes of detection, the installation is made even simpler since one device suits all applications. Whatever type of detection is required, it can be selected within the OSP software or from the panel menus at the time of commissioning – 3 different smoke modes, 2 fixed temperature heat modes, a rate of rise mode and additionally any combination of smoke and heat modes can be selected.

The Multipoint ASD detector is available with or without a full specification integral 90 dBA sounder resulting in no extra devices need to be purchased when audible warning is required. If extra sound is required or for areas that do not require detection, then a choice of several different standalone sounders, call points or sounder beacons are available.

The panels have been designed using significant customer feedback, to produce a high specification system with many unique features. Its appeal will attract consultants, clients, installers and engineers alike. The standard black high-gloss finish of the panels has been chosen to reflect the panel’s state of the art technology and to enhance its surroundings, rather than be hidden away.
