Only automatic and manual notification is required, preliminary notification of personnel is desirable, the customer does not require any additional services such as sound broadcasting. Answer : The minimum set of equipment for you: Devices Trombone - PU-4, Trombone - UM4 - 120W, Trombone - BP-07, actually sirens, light indicators "exit" and a microphone for the manual notification mode. If according to the sirens you do not fit into the 120W power, then you can take the next 240W amplifier and the Power Supply (there are 360, 480 and 600W amplifiers). Question : Trombone - BS 16. Is this device used only as part of the Trombone system, or can it be used as part of other systems? Answer : The Trombone - BS 16 device is designed for installation in the Trombone rack, however, despite this, it is a completely autonomous device and can be used independently, complete with the Trombone - VP outdoor panels. Question : How is the power supply of the Trombone - BS and Trombone VP devices carried out without the Trombone rack? Answer : The main power supply of the Trombone-BS 16 device is a 220V network, a rechargeable battery is installed inside the Trombone-BS 16 device for backup power. The outdoor panels Trombone - VP are powered by the Trombone - BS 16 device, regardless of the presence of a voltage of 220V. Question : Why are transfer cases with resistors installed on the communication lines in your system? Nobody else puts them. Answer: There is an industry standard for the construction of wire broadcasting systems. According to this standard, loudspeakers (sirens) must not be directly connected to the lines. Of course, OST has no direct relation to fire warning, but the main purpose of these resistors is to ensure the necessary reliability of warning lines, i.e. in the presence of resistors, failure of the sirens (short circuit) will not affect the operation of the sirens and basic equipment of the warning system remaining on the line. Unfortunately, in Asian systems, no one thinks about the reliability of warning lines, and in the event of a fire, short circuits are very likely. The second purpose of the resistors is to normalize the resistance of the warning lines. Question: According to SP6.13130.2009 p4.1, communication lines must be laid with ng-FRLS cable. Tell me if there is such a cable for voice transmission systems (there are control and signal ones, but I did not find telephone and communication cables). If not, is it possible to use a control cable for voice alarm systems of a long length of 300-500 meters? Answer : Communication lines must be laid with a fire-resistant cable, in addition, the cable must have normalized characteristics in terms of wave impedance, linear capacitance and attenuation. According to the manufacturer's information, these parameters for FRLS cables are within acceptable limits, so they can be used to transmit sound notification signals to sirens. Look for example cables on the link Question: What are the transmission line voltages for the TROMBON-UM4-600 amplifier? Answer : The supply voltages of all our amplifiers, including the UM-4-600, are the same and can be 30, 100 and 120 Volts.
