Automatic extinguisher control panel with 4 zone Gas fire extinguishing controller without battery. This control panel supports conventional fire detectors (i.e. devices which resemble the operating mode of open contacts during standby status, and resistors during alarm status). The panel has four fire zones for wire the smoke, heat, multi detectors and call point positive terminals to the terminal labeled “+” and the negative detector terminals to the terminal labeled “-“ as shown in figure 6 which shows the panel. Each active zone requires a 4K7 end of line (EOL) resistor at the very end of the zone . Zone1 and zone2 are releasing detectors, zone3 and zone4 are peripheral detectors. The control equipment is a combined fire alarm control panel and extinguishing system and has four detection zones, any or all of which are capable of contributing to the extinguishant release decision.
