KRK-4-BS PROT.R3, KRK-30-ALS prot.R3 radio channel modules provide the following functions:
- continuous two-way exchange between ACL segments as well as between addressable devices and the receiving and control panel;
- fire, failure alarms, addressable device (at extended part of ACL) testing message transmission to receiving and control panel;
- access to the settings and parameters of the addressable devices at extended part of ACL;
- LED indication of communication with receiving and control panel as well as between modules.
Through the radio channel, KRK-4-BS prot.R3 master module may be connected with up to four KRK-30-ALS prot. R3 slave modules.
KRK-30-ALS prot. R3 slave module has addressable communication line output where up to 30 addressable R3 protocol devices may be connected. These devices may be IP 212-64 prot. R3, IP 212/101-64-PR prot. R3, IP 101-29-PR prot R3, IPR 513-11 prot.R3 fire detectors, AM-1 prot.R3, AM-4 prot.R3 addressable marks, RM-1 prot.R3, RM-4 prot.R3, RM-K prot.R3 relay modules, MDU-1 prot.R3 smoke exhaust modules, MRO-2M prot.R3 voice announcement modules.
The KRK master module receives messages sent by the KRK slave module via radio channel, decodes them and transmits to the receiving and control panel. Through the KRK master module, the panel, in turn, transmits control programs to actuators connected to the slave KRK's ACL via the radio channel.
Modules shall be installed away from large earthed metal objects (beams, T-beams, gas pipes), in order to prevent from signal attenuation in these structures.
The largest extension of dedicated communication line by radio channel may be attained when modules are in direct view between each other
