    1. Types of Detector 1.1 Standard Detector The Standard Detector may be operated as a stand-alone unit, or may be part of a network of detectors centrally monitored by a Command Module (see section 1.2). It may be programmed via the front panel as in the version shown above. Alternatively, and for detectors ordered without front panel display, the detector may be pro- grammed remotely via the detector’s RS485 terminals using a Command Module, or via the detector’s RS232 port using a PC running...

  • Page 15 If the detector is in FastLearn mode, setting this function to No will stop the FastLearn process. Using the function in this way is neither recommended nor supported by Kidde Products Ltd Setting this function to Yes will start a FastLearn at any time. The bargraph display on the front of the detector will show a rolling segment display on the front panel for the fifteen minutes that it takes to complete.
  • Page 16 3.4.9 Auto FastLearn enable / disable (Yes/No - Address 001-127) Setup menu > Alarm levels As default, this function is set to Yes. This ensures that if the detector is powered down for any reason (e.g. for maintenance or to be moved to a new area), a FastLearn is commenced automatically on power-up.
  • Page 17 3.4.13 Latching faults (Yes/No - Address 000-127) > Setup menu Alarm actions When this function is set to Yes it requires a reset from the front panel or a remote reset to clear fault indications. This is the factory default setting. It may be applied to the Command Module or a Standard Detector.

  • Page 27 5.2 Mechanical The detector body is fitted to a wall-mounting bracket which is attached to the wall via installation the mounting holes E as shown below. The detector is then fitted over the mounting stud D and secured inside the detector body with the nut provided for the purpose. For a more discreet layout, it is possible to allow the sampling pipes and cables to enter the detector from the rear (see illustrations below), with the sample pipes and connection cables channelled into the wall.

  • Page 39: Interfacing

    8. Interfacing Because of the flexible nature of the Stratos-HSSD-2 ® detector and the many possible configurations, there are many options for interfacing the detectors to the Fire Panel. These include many third party interfaces available from various manufacturers. Because of this, it is not possible to give a complete list of all interfacing methods but the following pages will give details of the most common methods that are likely to be used.

  • Page 44: Commissioning

    When multiple detectors are networked together and a Command Module is being used, the PC connects to the Command Module‘s 9-way RS232 port. The cable connections are the same as the Standard Detector cable connections. 9. Commissioning Before commissioning the detector the local standards of aspirating detection systems must be consulted.

  • Page 45: Maintenance

    9.1 Commissioning The following brief checklist allows quick setup of the detector. This procedure will be checklist adequate for most standard installations. Before powering up the detector, visually check all cabling to ensure correct connection. If wire identification is not immediately clear (e.g. by use of different coloured wires or wire identification sleeves) an electrical check should be made.
  • Page 46 As dust contained in the dust separators may expose maintenance personnel to a ‘Nuisance Dust‘ hazard as defined by the ‘Control of Substances Hazardous to Health‘ (COSHH), it is strongly recommended that suitable masks and protective clothing be worn when changing filters. Used separators are not intended for re-use and should be disposed of.

  • Page 48 11.6 Flow fault errors • These occur when the airflow rate into the detector exceeds the pre-programmed parameters. As the detector ‘learns‘ the flow setup from the initial installation, this usually means that there has been some change in conditions. A Flow high fault may indicate that a sampling pipe is damaged, and a Flow low fault may indicate that the pipe has been blocked, e.g.
