  • Page 6: Topic 1: Vs-Mkii Control System

    VS-MKII Control System Topic 1: VS-MKII Control System Introduction Designed to comply with and tested to the requirements AS 5062, the VS-MKII Control System (“MKII”) comprises a control module, a remote display panel and audible alarm unit. The display panel provides visual indication of system status, alarms, and faults and also allows manual extension of the equipment shutdown delay.

  • Page 7: Standard Features

    VS-MKII Control System Standard features • • IP 65 rated control box Variable engine shutdown delay periods 0 - 240 seconds • • Cylinder low pressure switch input Variable shutdown delay extension period 0 - 240 seconds • • Discharge pressure switch input Slimline operator display •...

  • Page 8: Power Supply

    VS-MKII Control System Power Supply The MKII operates on a 24 Volt primary power supply (20-30 Volt range). If the system is installed in equipment that uses a 12 Volt power supply, a separate voltage converter will need to be installed to boost the voltage.

  • Page 9: Rechargeable Back Up Battery

    VS-MKII Control System When the panel receives > 31 volts for a period in excess of 10 seconds the amber ‘POWER’ LED • will light up (Fig. 6) but no audible or visual fault will be generated. In this state, the batteries will not be under charge.

  • Page 10: Topic 2: Installation

    VS-MKII Control System Topic 2: Installation Depending on the type and size of equipment requiring protection, the MKII can be configured with multiple actuation and detection devices. Figure 8 – Typical fire system configuration The MKII can be customised to suit just about any application. The settings that can be altered and the degree to which they can be customised are detailed in the ‘Channels’...

  • Page 11: Control Module

    VS-MKII Control System Control Module The control module (Fig. 4) comprises an IP65 rated enclosure and IP69 rated Deutsch DT series connectors and is the heart of the system. It can be installed with the factory (“default”) settings or configured to suit a specific requirement.

  • Page 12: Configuring The Module

    VS-MKII Control System Configuring the module It is recommended that any configuration changes that are required to the default settings be carried out before installation. It is preferable to use an external power supply to make configuration changes. When a stable primary power supply is present the ‘PRIMARY POWER OK”...

  • Page 13: Channels

    VS-MKII Control System LED’s The user interface is surrounded by a thick white border and the controls and indicators consist of; • A push button labelled ‘Channel’. • A push button labelled ‘PROG/SAVE’. 7-Segment • A 7-segment display. display • 8 LED indicators numbered 1 to 8 from left to right.

  • Page 14: Programming - Configuration Channels

    VS-MKII Control System Programming - configuration channels If the factory default settings are acceptable, no additional programming is required to the MKII before installation. If a new configuration is required your will need to re-program the system. It is recommended that a stable and constant power supply be present when programming the MKII.
  • Page 15 VS-MKII Control System Step 2 - Pre-programming When the desired channel is selected, change the dip switch positions using a flat bladed screwdriver (Fig. 20) to mirror the illuminated LED’s. (On LED = On switch.) some channels have configurations more then function, failure to perform this step may result in a undesirable configuration...
  • Page 16 VS-MKII Control System Step 5 - Saving changes After you have set the dipswitches to the desired positions, press and hold the “PROG/SAVE” button for 3 seconds to save the new configuration (Fig. 25). The system will now generate a fault which is designed to prompt a user to perform the next step.

    VS-MKII Control System Configuration channels (A-Y) A. Inputs and Outputs 1. The manual actuation input can be disabled when not in use. The equipment shutdown output can be disabled when not in use. Upon alarm, the alarm indicator on the Display will be activated and the buzzer output will start to sound once every second but the shutdown sequence will not start and the shutdown indicators will remain in inactive state.

  • Page 19 VS-MKII Control System Description - Auxiliary Mode The MKII incorporates an auxiliary output ‘AUX’ that can be interfaced with the engine management system of a third party device to signal one of the following events; 1. Alarm 2. System Fault 3.
  • Page 20 VS-MKII Control System C. Shutdown delays Shutdown Delay – Initial The default setting for the shutdown delay (the time it takes for the shutdown relay to operate after a fire alarm) is 30 secs. Shutdown delay times can be chosen in 5 second intervals from 0 to 20 seconds, 10 second intervals from 20 to 40 seconds, 20 second intervals from 40 to 180 seconds and 30 second intervals from 180 to 240 seconds.
  • Page 21 VS-MKII Control System d. Discharge delays Immediate discharge gives the suppression system the best chance of suppressing the fire in its early stages; however, in special circumstances delaying the discharge of the suppression system may be desirable. To cater for such circumstances, (such as operator safety) a discharge delay timer is provided with selectable delay periods - see Table 7.

  • Page 36: Electrical Manual Release Unit

    VS-MKII Control System Electrical Manual Release Unit The manual release unit consists of an IP65 rated metal enclosure with a glanded cable entry. A M18 cable gland and two bolts are also provided with each unit. It incorporates a switch fitted with a series and a parallel EOL resistor to allow it to be monitored for both open and short circuit faults.

  • Page 37: Operation

    VS-MKII Control System Operation When activated, the switch will change the circuit resistance (to approx 33 ohms) so that the panel can no longer see the EOL resistor (1000 ohms). The panel will interpret this new resistance as an Alarm condition. If the circuit is disconnected or shorted, the panel will interpret no resistance as a Fault condition in this circuit.

  • Page 38: Installation - Multiple Units

    VS-MKII Control System Step 5. Thread the cable through the gland and check that length and flexibility of the wires. Step 6. Connect the wires to the terminal block. A slight tug on the cable will confirm that the wires are securely clamped.
  • Page 39 VS-MKII Control System Step 3. Remove safety pin and loosen lock nut. Rotate switch assembly so that the circuit card is accessible. Remove resistor (R1) on each unit before the last. The last unit’s resistor remains to act as the EOL. Step 4.
