2. Scorpion is a remote tester specifically designed for testing ASD systems. Scorpion is compatible with the FAAST aspirating smoke detector. It is particularly useful for ASD testing in hard-to-access locations, such as in lift shafts, secure or hazardous facilities or in areas which are in use 24-7 such as airports and processing plants. Please take care when installing Scorpion at height and observe any safety requirements.   The Scorpion system includes a Control Panel, a rechargeable Battery Pack and a Head Unit.

3. Installation of the Control Panel The Control Panel is normally positioned adjacent to the ASD test unit. If there is a recessed cable box you can screw the Control Panel directly to the box, or you can use the surface mounting box provided in the kit. Remove the back of the Control Panel by undoing the two screws on the top. Feed through the cables and secure the Control Panel to the mounting box with the two screws.

4. Note the terminals A, B, C and D
Note the terminals A, B, C and D. These will later be connected to the corresponding terminals in the Head Unit once it is installed. Take note of the cable colours as they are connected to the terminals.

5. Installation of the Head Unit The Head Unit can be installed at the end of the ASD pipe or adjacent to one of the air sampling holes. Use the appropriate Smoke Presenter.
In this case we will mount the Head Unit at the end of the ASD pipe.
It is important that the Head Unit is mounted “downwind” of the ambient air movement within the room. Crosswinds or turbulent air may blow the smoke away from the sampling hole.

6. Fit the Smoke Presenter to the ASD pipe end cap making sure that it does not obstruct the sampling hole.
Make sure the bracket is the correct way up by ensuring the fold at the end of the bracket is turned upwards.

7. Fit the brackets to the ASD pipe “un-locked” so that the Mounting Bracket can be adjusted later.

8. Remove the Head Unit from the polythene bag and hold it with the labels facing upwards. It is very important that from this point you keep the Head Unit facing this way up and horizontal. It contains fuel which could leak out once the transport plugs are removed. First remove the yellow transport pin by turning it clockwise and pulling out. There are two separate parts. Rotate the outer pin clockwise while pulling firmly. Once this is removed, twist the inner pin counter-clockwise slightly - about one eighth of a turn, and then pull out. The inner pin needs less force than the outer pin.

9. Now unscrew and remove the fuel breather plug.
Be sure to keep the Head Unit the correct way up and horizontal as you and offer it up to the mounting bracket.
If the bracket is the correct way up, the Head Unit should slide onto it. Push it on as far as it will go. It should grip tightly onto the bracket.

10. Insert the flexible tube between the Smoke Presenter and the Head Unit
Insert the flexible tube between the Smoke Presenter and the Head Unit. Make sure it is a tight fit by sliding the head towards the end pipe. Check that the Head Unit is horizontal and “lock” the pipe brackets to secure them to the ASD pipe.
Squeeze it gently and “wriggle” it free if necessary.

11. Loosen the cable clip. Strip back the cables by approximately 10mm
Loosen the cable clip. Strip back the cables by approximately 10mm. Push them into the terminals with the colours corresponding to the letters A, B and C of the Control Panel, as we mentioned earlier. The terminals will ‘grab’ the wire a you push it in. If you need to remove the wires, use the tool provided by locating the lugs in the space beneath the white terminal blocks and pushing upwards. Or, you can use a screwdriver to push individual blocks inwards.

12. Replace the cable clip and fit the terminal cover back onto the Head Unit. Check once more that everything is tight and the Head Unit is horizontal. You may find it easier to wire the Head Unit before pushing it onto the bracket. This is not a problem provided that there is sufficient slack cable and you keep the Head Unit with the labels facing upwards and holding it horizontal to prevent any fuel leakage.

13. Using the Scorpion System Refer to the Scorpion User Manual online or in the Control Panel Installation and Operation Guide for instructions on charging the battery and using the Control Panel. A fully charged Scorpion Battery Pack (or a Solo 760 Battery Baton) can be connected to the Control Panel to test the system.

14. Technical Specification
The following specification should be used for project planning / quotation purposes
The tester must be capable of conducting a functional smoke test on aspirating smoke detection (ASD) systems from a wide range of manufacturers. The smoke generating head unit must be suitable for testing at either the end sampling hole or a sampling hole along the length of the pipe. It must be capable of delivering in excess of 240 smoke tests of 15 seconds duration each.
The head unit should capable of being wired to a controller at least 100m cable length away. It shall be possible to connect at least eight (8) head units to each controller.
The controller should be powered from a removable battery to prevent unauthorised testing. The controller should allow each head unit to be selected individually and start/stop the smoke test.
The duration of the smoke time must be configurable from the controller, from 5 seconds to at least 45 seconds. It should be possible to measure the transport time from the control panel for ASD systems using an integral timer display
