The control panel (fire station) is an integral component of fire detection and fire alarm system, which is intended to supply and supervise the work of other system components. It receives and processes signals from fire detection devices, establishes operating modes of the system triggers audible and light signals, but also can inform the remote alarm center and to store details about events that occurred. By means of specialized software program control panel can be configured to react a particular way and to perform specific functions inside the new event.The control panel is powered by the AC network, but demands a backup power supply that offers the system with power cuts. Most usually it’s secured by two pieces of 12 V batteries. Extra power supply can be placed inside the panel itself or to be configured as a separate unit, which is suitable particularly for larger systems with considerable overall consumption.Four access levels are accessible when working with fire detection panel, enabling distinct rights to distinct operators to monitor, configure and change system settings. Access Level 1 is with the smallest rights, although in level four all achievable operations are permitted. Log in into a given level is protected by password, which must be distinct for various levels if other operators are allowed to work with the system.Fire station indicate the status of FDS following processing the signals from the devices inside the system defined by developed algorithms. According to most of todays standards scanning, signal processing and choice producing for fire alarm signaling should take place in no more than 10 seconds.The following are possible modes of the system:• Regular state (Typical / Quiescent condition)• Fire (Fire)• Failure (Fault)• Exclusion devices / functions (Disablement)• Verification (Test)Fire station state might be a combination of two modes, except the very first. Modes are indicated by light indicators in green (typical), red (fire) or yellow (“Damage”), accompanied by a short text on their individual conditions.In regimes “Fire” and “Damage”, audible alarms might be triggered, derived from the panel itself (built-in buzzer) or included inside the system of sirens / bells fire. It might be the identical for fire and technical failure. If the system consists of strobe / flash lamps, they’re also triggered. Sound and lighting equipment may be excluded by the corresponding button for attenuation, which becomes active right after the entry into any of the access levels.For control panels that support light indication of areas, zone / zones in alarm mode are indicated by the LED indicators on the panel. If the fire station has a display, the zones in alarm state are indicated by text message. When is “Fire” mode, the panel goes back to typical function after setting the “Reset”, which in most circumstances is active within the push-button obtainable for access level 2 and greater.The control panel can send alarm signals to a remote observation center – security business or Fire Department. This is completed through numerous enhancements – dialer, modem or Ethernet module. These devices use various strategies for data transfer – modem dialer use the phone line, Ethernet module – a local personal computer network or the internet.In order to check the system for alarm received – whether there is actually a fire or malfunction, or a false bedding, there is an alternative for particular sub-modes – time delay and confirmation of alarm.In sub-mode “time delay”, there’s a time delay for the system going in “Fire” mode, as a way to perform a system check and only then light and sound alarm devices are activated. In case of fire detected by human, fire alarm may be activated by pressing among the manual fire detectors or by operator with lowest access level.Sub-mode “Confirmation of alarm” enables bedded in a detector system to be confirmed by the identical or a diverse detector within the region and only then to put the fire detection system in “Fire” mode. This sub-mode is also achievable in the “cross zoning” method (crossing of two cable lines with detectors), where the “Fire” mode is activated soon after the simultaneous or within a particular range of bedding devices on both lines.Lowering false bedding is feasible with the use of “day” and “night” modes by which the detection system is assigned a various sensitivity in both sub-modes. In “day” mode detectors are much less sensitive than inside the night, since numerous activities conducted throughout the day can cause false alarms.Modern control panels possess various characteristics, some of which are mandatory for all. The capacity for options setting is one of the major factors that makes fire stations suitable for use in distinct size and application web sites, and is also a main mean to increase their competitiveness.
