1 DESCRIPTION AND OPERATION OF THE SYSTEM
1.3 Description and operation of the system
The System is a hardware and software system that includes SC described in section 1.4.
Depending on RCD type, the System operates in one of the following modes:
а) in call mode when RCD and remote calling stations are connected by RS-485 network or four-wire communication line;
b) in call bell mode when a push-button sends signals to signaling unit.
During operation, remote stations call to central or additional RCD, initiating sound and light alarm signaling and displaying the address of the calling station.
In call bell mode, call button sends a call and supplies power to a signaling unit, and by that, switching it on.
RCDs of all types (except SCS-WP) and remote calling stations SCS-CH and
SCS-REF connected via RS-485 set up local data exchange network.
RCDs SCS-SPS-5, SCS-SPS-10 may operate with 5 and/or 10 remote stations in common network, and SCS-CU and SCS-CU-REP – with 32 remote stations.
RCDs SCS-SPS-5, SCS-SPS-10 may also operate via four-wire communication line.
RCD SCS-WP type allows for direct button connection via four-wire communication line.
Once remote station sends a call, the System operates in the following order:
а) if remote stations are connected via RS-485, a remote station controller registers a signal, then actuates local signaling units and sends a call signal to RCDs SCS-SPS-5, SCS-SPS-10, SCS-CU, SCS-CU-REP types that display network address of the calling station.
The call actuates local alarm on the RCD and repeater SCS-CU-REP and switches light indication of the calling station number (name);
b) if call buttons are connected via four-wire line – firstly, local signaling units actuate; RCDs SCS-SPS-5, SCS-SPS-10 and SCS-WP register signal on the corresponding port, and then actuate local and external call alarms;
c) in call bell system a signaling unit is switched on by push-button.
Once the call is received, an operator may use Mute function (call bell system does not provide this function) and temporarily mute sound signaling by corresponding button on RCD.
Sound signaling will be switched off both on RCD and repeater SCS-CU-REP;
light indication on both units will change from flashing to constant lighting.
An operator may also mute sound signaling on the repeater, but RCD signaling will be still working.
Sound signaling muted by RCD or repeater will resume after time interval (timer), if during this time the call has not been reset at the calling station. Set time interval in the settings.
Only when the call is reset (by Reset/Mute button) on the calling station, alarm signaling will be switched off on RCD, repeater and remote calling station.
Button «Mute/Reset» on SCS-WP switches off sound alarm and resets call signaling.
To reset a call in call bell System, return button to the initial position.
Therefore, the System operates in the following order:
а) remote calling station initiates a call to watch officer station and backup station where local signaling actuates;
b) an operator mutes sound signaling on RCD and heads to the calling station;
c) at the calling station the officer resets the call and investigates the reason of the call.
Depending on System application, we recommend the following System configurations, see Table 2:
а) for a ship’s hospital, according to Figure 1;
b) for refrigerated holds and refrigerator units, according to Figure 1;
c) to call a watch officer according to Figure 2;
d) as a call bell system according to Figure 3.

Operation of SCS-CU and SCS-CU-REP LCDs: after turning on and in wait mode LCDs of SCS-CU and SCS-CU-REP display status of controlled remote stations. The stations are shown as screen areas with numbers and text information, see Figure 6.
Figure 6 – Working mode of SCS-CU and SCS-CU-REP
Each screen area (indicator) may operate in the following modes or their combination:
– no call (normal);
– call (call detected);
– no station connection;
– buttons failure (error) or communication line failure.
Each mode (except normal) may have active (when call received) or reset status (once an operator resets/mutes the call):
– active status is supported with flashing light and intermittent sound signaling;
when connection with station or call button is lost, а corresponding screen area is crossed with flashing red cross and displays «No connection» or «Button failure». In the first case a red frame with a cross appears on the indicator’s area; in the second case – only red frame;
– reset status is supported with bright glowing of indicator; if connection is lost, indicator’s frame (perimeter) remains red.
An indicator’s area returns to an initial view once the call is reset or connection recovered.
2.1.3 Reception and control device SCS-WP
Any call button connected to the device may send a call.
The functions of the SCS-WP:
а) to control signals from call buttons connected directly to SCS-WP;
b) to actuate alarm immediately if call button sends a call;
c) to control one connected line (station). Several call buttons may be connected in parallel;
d) to reset call by «Reset/Mute» button on the device, or temporarily mute sound signaling (depending on selected operation mode);

2.1.4 Repeater SCS-CU-REP
Repeater SCS-CU-REP receives a call signal from remote stations in data exchange network.
Use the repeater if you need additional control over calls from remote calling stations (along with the main station) and (or) RCD operation.
As a System component, the unit repeats RCD; it may also mute local sound signaling.
Note – RCD may be used as a repeater (in repeater mode).
The unit has the same functions and controls as SCS-CU, except a button to supply power to the connected devices.
Mute mode of the repeater is independent, and does not influence sound signaling of the main RCD.
