Central annunciator units MRZS-O

It performs the following functions:

• monitoring and recording of discrete input signals, including pulse signals;
• monitoring and recording of group signaling input signals;
• generation of discrete output signals;
• monitoring of audio-visual signaling status;
• receiving and displaying alarm and warning signals with or without time delay;
• visual indication of input states;
• control of sound signaling (up to seven sound signaling devices) with automatic acknowledgment capability;
• transmission of signals to group signaling;
• transmission of signals to external visual signaling devices, including flashing mode;
• communication with higher-level control, data transmission and reception of signals with the ability to affect internal logic, LEDs, relays, acknowledgment.

Number of inputs

• 28–56 freely programmable discrete inputs
• 0–4–8 inputs with current increment measurement for group signaling (GSS)
• 0–1–2 analog inputs for control of operating voltage value - operation by current in the device does not depend on voltage level (GSS operation by resistance).

Number of LEDs

• 60 freely programmable single-color
• 2 service three-color LEDs:
  • device healthy/faulty status
  • sound signaling operation

Number of discrete outputs – 9

• 7 relay outputs
• 2 power outputs
• all outputs freely programmable, including pulsing light relay

Buttons

• 3 service buttons: sound signaling off button “Silence”, indication reset button, LED test button
• 4 freely programmable buttons
• 6 navigation buttons

Free programmable logic

Interfaces: RS-485, USB, Ethernet (RJ-45 or optical ST);
