  • Page 4: Important Notes - Please Read

    Digilite® fittings generally incorporate an LED which readily displays the current status of the fitting. Green is normal, Flashing green indicates the fitting is being tested, flashing amber indicates the unit has a fault or has failed a test.

  • Page 5: Cabling Requirements

    Loop Wiring The Digilite® loop wiring carries both power and data to the Digilite® fittings. In order for the system to operate correctly the voltage drop along the loop must be kept within certain limits. The loop wiring must be wired from the panel terminal marked ‘LOOP1 A’ round all the fittings and reconnected at the panel terminal marked ‘LOOP1 B’.

  • Page 7 The maximum go and return cold resistance for a spur with 100 fittings may be calculated as follows. = 8 – ( 16 x 340 x 0.0004 ) spur (max) ( 100 x 0.0004 ) = 145 Ω spur (max) N93-561-85 Issue 0 © Copyright Protec Fire Detection plc 2009...

  • Page 8: Insulation Testing Of Cabling Prior To Connection

    Insulation Testing of Cabling Prior to Connection Before connecting any external cables to any field device or the Digilite®, tests must be carried out TM’ using a 500V DC insulation tester (‘Megger ). The readings between each cable core, and each core and earth should be greater than 10MΩ.
  • Page 9 Removal of the Main PCB. NOTES ON ANTI-STATIC HANDLING OF THE PCBs Before handling any of the circuit boards in the Digilite® it is vital that any operatives discharge themselves of any static charge that may have built up on them. This can be done by momentarily touching a solid earth point (a non-painted part of a radiator, for example).
  • Page 10 DO NOT SWITCH MAINS POWER ON AT THIS POINT ! Route the battery cables through to the battery compartment using the channels provided. If fitted reconnect the wire from the rear of the Digilite® main board to the interface fitted in the centre channel of the enclosure.

  • Page 11: Commissioning

    Commissioning Connecting the Loop The Digilite loop wiring must always be connected as a complete loop from the panel to each outstation, then back to the panel again. Please see figure 7.0 The loop wiring carries both power and bi-directional signalling to the Digilite outstations.

  • Page 12: Installing And Connecting The Standby Batteries

    Installing and Connecting The Standby Batteries The panel is designed to house two 12V 3.3Ah Valve Regulated Sealed Lead Acid (SLA) batteries. These fit into the left hand compartment of the Digilite® and should be secured with the Tie-wraps provided.
