Signalling loop extenders RSH "Jupiter-381x", which is a technical means of protection (hereinafter referred to as TCO) of the object subnetwork.
The TCO is designed to increase the number of alarm loops (hereinafter referred to as loops) controlled by the object terminal device (hereinafter referred to as U00). The protection is performed by monitoring the status of two-wire alarm loops of the intrusion detectors installed at the protected object by the TCO and transmitting the alarm loop status notifications to the UEO.
The TCO monitors the state of two-wire alarm loops by changing their resistance.
The TCO is available in two versions:
- version 00 (Jupiter-3811) - control of 4 alarm loops;
- version 01 (Jupiter-3812) - control of 8 alarm loops;
Notifications about the alarm loop status are transmitted to the monitoring station via the RS485 interface (EIA 485 standard).
TCO as part of the object subnet provides its identification by the AEO software in order to exclude the possibility of substitution.
