The fire alarm control panels (4 Zones, 8 Zones, and 16 Zones) provide all of the sophisticated features required of a leading edge conventional fire alarm system along with the simple operation and efficient installation methods demanded by both installers and building users. The panel can be flush or surface mounted and the generously sized metal back box allows ample space for rear or top cable entries. A comprehensive range of auxiliary devices is available to operate with the fire control panels including optical, ionization, photoelectric, and heat detectors. Each of the system components has been specifically designed to operate as part of the system. This provides assurance that the control panel, smoke detectors,interface devices and the ancillary components are all fully compatible with one another and that the full range of system functionality is supported by each device.
