Units of coordination "Raskat", (hereinafter - BSR), are designed to work in conjunction with voice announcement devices "Raskat" and allow you to connect to one network of acoustic (acoustic) system (systems) (AC - U - 5) several blocks of voice announcement " Rollout ”(BRO), which can be installed in different rooms and have different recorded speech information. BSRs provide priority connection of BRO with a lower number in relation to BRO with a larger number and exclude simultaneous broadcast of a voice message from several BRO. BSR are designed for installation inside a protected facility of varying degrees of complexity and are designed for round - the - clock operation. BSRs are relay switches controlled by warning signals from BRO. IWUs are recoverable, controlled, serviced.
BSR meets the requirements of NPB 77 - 98.
BSR are not a measuring instrument and do not have precision characteristics.
BASIC CHARACTERISTICS OF BSR
The power supply unit is powered from an external backup DC source (with a battery) with a rated voltage of (12 ± 1.2) V.
BSR is designed for continuous round - the - clock operation at ambient temperatures ranging from minus 10 to plus 55 ° С and relative air humidity up to 93% at 40 ° С.
BSR is not a measuring instrument and has no precise characteristics.
There is no current consumption of the device in standby mode
Average current consumption of the device in the notification transmission mode from an external power source is not more than 0.11A.
Maximum switching voltage of the relay, no more than 30 V.
Maximum switched relay current, no more than 2 A.
Maximum switching power of the relay, not less than 60 W
Overall dimensions of the BSR are no more than 84 x 61x 40 mm.
The mass of the BSR is no more than 150 g.
The degree of protection of the BSR provided by the shell corresponds to IP 41 in accordance with GOST 14254 - 96.
INSTALLATION AND SETTING PROCEDURE
Install the BSR at a guarded facility next to the Raskat BRO, with which it will work. According to the diagram, install the connecting lines connecting the BSR with the BSR and AS - U - 5, as well as with the BSR of the subsequent BRO "Raskat". Connect the IUU with an external 12 V backup power supply. Check the correct installation. Switch on external backup power supply. When the power is turned on, the system is tested (a pre - recorded voice message is played and the contacts of both relays installed in the IMS are switched during the message playback). Alternately short - circuit terminals 3 and 4 (control) of each of the BROs included in the system, and check for the presence of a voice notification. Close the covers of all BRO and BSR, the system is ready for operation.
When installing and operating the device, it is necessary to be guided by the "Rules for the technical operation of consumer electrical installations". Install, remove and repair the device with the power off.
