Operator Control Panel OCP

The OCP Operator Control Panel is intended for R3500 Fire Alarm Control Panel functionality expansion. The OCPs is connected to the R3500 Panel via two independent “MMIBus” interfaces and are used as redundant remote control panels. Up to eight OIP40s can be connected via two independent “CLBus” interfaces additionally.
Power supply 24 V
Consumption current, up to 3 W
Maximum length of MMIBus interface 1000 m
Maximum number of OCPs connected to:  
R3510 8 pcs
R 3520, R3530 7 pcs
Maximum number of OIP40 connected to OCP 8
Dimensions (WхHхD), mm 320×253×33
Weight, up to 1.3 kg

The Operator Control Panel has a plastic casing.

The main OCP functions:

     1. Signal processing from the R3500 Fire Alarm Control Panel;
     2. Transmission of the operator’s commands via the MMIBus interface to the R3500 panel.
     3. Backup of the R3500 controls.
     4. Indication of R3500’s status by a built-in display and audio signals.

The panel can be embedded in the R3500 panel casing (at the manufacturing plant only) and operate with R3500 as a separate device connected via the MMIBus interface.

In case the R3500 panel is used in the R3510 design variant, up to eight OCPs can be connected via the MMIBus interface. In case of the R3520 or R3530 design variants, the maximum number of the external OCPs is 7.

The maximum distance between the last OCP in a line and R3500 connected via the MMIBus interface shall not exceed 1000 m.

The MMIBus interface can be backed up. For the interface backup, two independent lines are used; for the lines, shielded twisted pair shall be used.

If the OCP is used in a plastic casing, its power supply is provided by a 24 V external power source. If the OCP is embedded directly in the R3500’s casing, the power is supplied by the built-in PMU-5 unit.

Up to eight OIP40 indication panels can be connected to each OCP; connection can be provided via the CLBus interface. The maximum distance from the OCP to the eighth panel OIP40 shall not exceed 10 m.

CLBus is a ring interface. The power to the OIP40 panels is supplied directly from the CLBus line.
