FIRE DETECTION

Fire Detection

Presentation

The Fire Detection system consists of one or more fire alarm panels and various fire detection and alarming devices connected to the panels. The panel is a controller that monitors addressable loops. Non-addressable devices can be connected to the panel through interface modules. Panels can be connected in a network configuration for improved detection capability and functionality. The self-verification aspect of the fire detection system eliminates time-consuming inspections and maintenance.

Various detector types are:

  • Smoke detectors
  • Heat detectors
  • Multi-sensor detectors
  • IR/UV flame detectors
  • Manual call points

The Fire Detection system can work independently from other components of the FGD100 system, or can be fully integrated into other various safety systems carried by Jelec. There are two possible Fire alarm system configurations integrated by Jelec, a stand-alone option and a networked option.

Stand alone option

The stand alone option is suitable for small areas, or more precisely, a small number of fire zones.

This system is composed of a main Fire panel to which are connected several loops of heat detectors, smoke detectors, flame detectors and manual call points as in any Fire Detection system.

The Fire panel is a programmable controller which runs the Fire Detection and configuration program customized by Jelec to fit customer needs.

An operator can access the panel functionalities and thus the system configuration through the operator interface. The operator interface consists of an LCD display and a keypad that permits the customer to navigate through the different menus in the operating system software.

Network option

The network option is suitable for Fire Detection coverage of wide areas. It is often more economical to provide multiple panels and connect the detection loops to these different panels located in different parts of the facility. This reduces the cable work greatly and provides a more reliable system for fire detection. It also provides a more logical partitioning of the Fire Detection zones, thus simplifying the maintenance operations as well as the Fire crew work.

The system consist of a main Fire panel, also called a boot panel, to which are connected several remote panels through a ring shaped network. The network medium can be copper wire or fibre optic.

Loops of heat, smoke, and flame detectors as well as manual call points can be connected to any panel in the system to monitor virtually any size project.

Interfacing with other systems

The Fire panel can also control and monitor other types of equipment. The loops can be equipped with digital input or output modules.

With addressable output modules in the detector loops, it is possible to control alarm signalization devices such as horns, sirens and strobes that can be located all across the facility. It is also possible to control magnetic doors.

Through input modules, the Fire panel receives data from other external equipment or devices. Typically, the Gas Detection system communicates alarm signals to the Fire panel which in turn, relays them to the annunciation devices (beacons and horns) across the facility.

The Fire panel data can be transferred to the HMI or a third party safety system through a serial data connection. For this purpose, the Fire panel can be equipped with a communication module and an interface convertor compatible with the required communication protocol.
