    In Use In Use An Entry Control Officer (ECO) is a competent person nominated to control and monitor an Entry Control Board (ECB) and to direct and instruct all wearers of breathing apparatus (BA) at an incident. A safe and secure entry control point (ECP) for the ECB should be established from which the ECO is able to effectively control the adopted procedures.
  • Page 14 In Use  During the logon sequence the following visual changes take place on the ECB and the electronic monitoring system: 1. The channel screen momentarily displays the electronic monitoring system identification number, followed by the time elapsed count (E :00), then changes to the default Time of Whistle (TOW).

  • Page 15: Monitoring Data

    In Use Making Contact ‒ Manual 5.2.2 An unsuccessful logon identified by an initial momentary display of the fault code (Et) followed by the display changing to E :00 (time elapsed count), indicates a probable defective transponder in the tally (a faulty tally must be reported and replaced as soon as possible). A single audible beep alarm is emitted until the manual logon is started.

  • Page 39: Appendix D - Manual Operation Of Ecb

    Manual Operation of ECB Appendix D – Manual Operation of ECB ® ® As outlined in the introduction section of this Instruction for Use, the Dräger PSS Merlin Entry Control Board (ECB) provides a means of remote two-way digital data and alert status communication between the ECB and electronic monitoring system on breathing apparatus.

  • Page 40: After Use

    Manual Operation of ECB  Refer to the appropriate Working Duration table to establish the remaining time (in WORKING DURATION minutes) available to the wearer. This can be interpreted and recorded as either: BASED ON 55 BAR WHISTLE SETTING AT 40 L/MIN BREATHING RATE 6.8 L 300 Bar A time elapsed to whistle activation.

  • Page 41: Appendix E - Propagation

    Propagation Appendix E – Propagation The signal power of a radio frequency transmission diminishes over distance. Signal power will also decrease in strength as the radio wave passes through solid objects such as terrain, trees, walls, windows and the floors of buildings, storage tanks, underground (tunnels), etc.
  • Page 42 Propagation To maximise propagation of the transmitted radio signal at an incident, the antenna of the ECB should be positioned as high as possible above the ground to minimise transmission losses that may be caused by objects on the ground and also to reduce the effects of radio waves reflected from the ground.

  • Page 43: Enhancing Transmission

    Propagation Enhancing Transmission E.2.1 Repeaters As outlined in the preceding sections, the critical factor influencing the maintenance of positive radio contact is the location of the antennas. There are some instances where an RF propagation problem could result in some, or all, of the electronic monitoring units losing radio contact and becoming unable to communicate directly with the ECB.
  • Page 44 Propagation Possible locations for Repeaters are inside the entrance of a building, at the top of basement stairs, the bottom of stairs, at the entrance to, or at a sharp corner in a corridor or tunnel, etc. In reality, as illustrated, the actual spread of the radio signal may mean that the optimum position may be at some point further down the stairs, or in the case of a tunnel, further into the entrance.

  • Page 45: Customer Evaluation Trials

    Propagation The following illustrations show two possible system layouts. For clarity the coaxial cable is shown coiled on the winding reels but for operation the cable would be fully unwound from the reel. Single Repeater 2852 Two Repeaters 2853 Refer to the Instructions for Use provided with the Repeaters and Leaky Feeders for full details. Customer Evaluation Trials It is important to be aware that radio communication can be affected by a breakdown in the transmission signal due to extremes of application such as long distances, building construction, below ground structures, etc.
