These are heat and smoke detectors with individual addresses. When a sensor is triggered, the system can identify exactly which point is in alarm, especially if the system is integrated with a graphical interface at the fire alarm control panel (FA panel).<\/p>\n
The FireNet addressable fire alarm system uses the advanced Digital Communication Protocol (DCP), developed by Hochiki. This protocol enables high-speed, accurate communication between the devices and the control panel, minimizing signal interference during transmission.<\/p>\n
Thanks to DCP’s strong noise immunity, the system can use standard cables, without the need for shielded or twisted-pair wires like other systems require. This results in cost savings while still ensuring reliable and efficient operation compared to other addressable fire alarm systems.<\/p>\n You can use conventional detectors in an addressable system, but you’ll need a monitor module (also called a zone module, depending on the manufacturer). Each module of this type can be connected to around 14\u201317 conventional detectors. These modules can also be used to monitor the status of other equipment, such as fire pumps, generators, fire suppression valves, etc.<\/p>\n This module controls 24VDC alarm bells. If you’re using 220VAC or 24VAC bells, or bells with high power requirements, then you\u2019ll need a relay module instead.<\/p>\n In places where multiple monitoring and control points are concentrated \u2014 such as water pumps \u2014 and you want the FA system to both control and monitor these devices, you will need multiple inputs and outputs. In such cases, an I\/O module is required for the addressable fire alarm system.<\/p>\n These detectors share the same general characteristics as addressable smoke detectors. They are usually installed on the ceiling, in areas where heat is expected to be the first sign of fire in the surrounding air.<\/p>\n When heat is emitted from a fire source, it activates the heat-sensitive component of the detector, which then triggers an alarm signal sent to the addressable fire alarm control panel.<\/p>\n There are two types of heat detectors:<\/p>\n Fixed Temperature Heat Detectors: These activate an alarm when the surrounding temperature rises to a pre-set threshold \u2014 for example, 58\u00b0C, 68\u00b0C, or 108\u00b0C.<\/p>\n<\/li>\n Rate-of-Rise Heat Detectors: These activate an alarm when the surrounding temperature rises rapidly within a short time, for example, 6\u00b0C\/min or 8\u00b0C\/min.<\/p>\n<\/li>\n<\/ul>\n After reading this article, you should have a better understanding of addressable fire alarm systems<\/strong>.
