Smoke detectors are two types of optical and ionisation. They are effective against smoke (white and black smoke). Selection stater bros will be protected stater bros while the risk of fire in the area should be considered. An electric current flows between the two electrodes in the ionization smoke detector. This current is reduced when the smoke. If smoke is detected by a smoke detector in optical light distribution.
Heat detectors can be set to detect the type or types of temperature increase is set to a constant temperature. They are less sensitive than other dedektörier. Should be used where the possibility of the emergence of small fires. Able to detect small changes in temperature. 20 degrees above ambient temperature, while the selection of heat detectors must be careful not selected.
In case of a passing fire alarm system motion clips and bits of fire alarm buttons are products that allow staff to give the alarm. These buttons; To give an alarm to go away more than 30 meters from any point, stater bros the readily accessible point 1.4 meters above the ground and without blocking must be mounted in a good way.
Silenced by pressing the panel reset button when you check to see if it is running and functioning of all indicators built-in siren. Provide to give warning of the panel by opening a fire alarm buttons to test the fire alarm. Check that the sirens are working. Reset the fire alarm panel. Each of which may be tested at least three months alternately select one of each week. In addition, a different fire alarm buttons for each test and use the siren. In this way, all fire alarm buttons which will be tested alternately. Must be of fire alarm and dedektörier butonlann building plans showing the layout. stater bros Performed these tests should stater bros be recorded regularly.
In its simplest stater bros sense, the system has a fire panel. Panel from various types of sensing elements (detectors, buttons, etc.) That fits in evaluating warning devices (sirens, flashers, etc.) Into the active state. Fire Detection Systems evaluated in two separate sections in terms of working principles.
The detection panel used in the system consists of are connected to the sensing element. The number is related to the capacity of the panel area. (2 ... .64) Each of the 20 sensing element stater bros (detector) can be connected. The panel also has inputs and outputs to connect the fire alarm buttons and sirens. When any detector or fire alarm detection do when button is pressed, the panel said on sensing element which belongs to the area corresponding to the signal comes from that region. For example: If you make any detector detection in a region which is connected stater bros to the detector 20 will wake up from that area. (But it will not be clear warning which comes from the detector.)
Loop is connected to the addressable system in the sensing element (loop) lines are available. The number of the loop line and connected to the panel wiring distance is used. A loop line 128 units addressable elements (detectors, buttons) can be connected. Sensing elements embodied in the loop on each sensing element as can be separated into its own in the region detected by individual aderesl but thanks to the switch panel. So whenever a detector sensing the location of the detector can be detected on the panel made individually. Conventional systems and addressing system is dimensioned according to the selected application areas. Conventional elements for a small number of sensing element within the host system offers sufficient and inexpensive solutions.
DS 240 beam type smoke detector consists of two separate parts. Receiver (receiver) and transmitter (transmitter) units. Transmitter stater bros by the unit, with special frequency and intensity of invisible infrared beam is transmitted to the receiver unit.
Conditions in order to introduce the analogue addressable system is download the possibility of false alarms to a minimum. In addition, it is observable that the panel from which the alarm detector, finding the source of the fire in a short time and it is possible to be able to intervene. Errors / mistakes to minimize the use of protected areas that can take analog isolators cycle of loss does occur, it is possible. Are thus isolated in the error occurred stater bros is prevented from operation of other regions. Conventional systems of errors in an area that is separate from each circuit impedes that of the entire operation.
