Ex-Or RB2000LT - Power Supply Installation And Commissioning Manual

Introduction

Only suitably qualified personnel should install this equipment.

The RB2000LT powers and synchronises the MLS Bus for up to 100 MLS devices. Wall switch inputs allow simple dimming and on/off control over suitably programmed devices in the system. There is no provision to link multiple RB2000LTs together.

Fixing

The RB2000LT is supplied in a protective housing which should be mounted where it is accessible for commissioning purposes.

Connection

It is imperative that the MLS bus is wired with the correct type of cable; normally it should be 1.5mm² unscreened twisted pair. Please read Application Note AN4001 for more details. As the MLS Bus is polarity-conscious, care must be taken to maintain polarity throughout.

Do not connect mains to the MLS bus as this will cause irreversible damage to all devices in the system.

The mains supply, MLS bus and switch input terminals are suitable for 1 x 4mm² or 2 x 2.5mm² cable.

Centre-off, three-way, momentary wall switches should be connected to the 'Wall Switch' UP and DOWN terminals. Centre-off, three-way, latching wall switches should be connected to the ON and OFF terminals. Each command actioned by the switch is addressed to all devices programmed to operate on either Zone 1 or Zone 2 of the MLS Bus System. All other Zones remain unaffected by the switch inputs.

Important Additional Notes

1. All terminals on this product are provided for final connections. It is not intended that the product be used as a junction box for looping cables.
2. A means for disconnection must be incorporated in the fixed wiring in accordance with the current wiring regulations.

Commissioning

The RB2000LT has two modes of operation, depending on what range of equipment the unit is being used in conjunction with.

Located at the bottom, left-hand corner of the unit is a four-way DIL switch. Switch number 4 determines what bus type is being used. For 1200 Series detectors and equipment (e.g. MLS1200DIS) this switch should be set in the ON position. By default it is set to OFF - for use with 2000 Series equipment (e.g. MLS2000PF).

Switch number 1, when set in the ON position, allows the RB2000LT to operate in 'Commissioning' mode. In this state, any detector or device in the system which is programmed to any zone (via an HP2000) can then be turned OFF by infrared override. This override command will filter down to every device in the system enabling the operator to see that the bus cabling is installed and functioning correctly.

Switches 2 and 3 have no function.

1. 4-way DIL switch. All switches set to OFF by default. Switch 1 enables commissioning mode; Switch 4 determines bus type.
   Switches 2 and 3 - no function.
   
2. MLS Bus connections. Do NOT connect mains to the MLS Bus. Polarity must be maintained.
   
3. Switch input connections.
