    In addition, if it works in an alarm loop system (see sections 6.2, 6.3), at its input (via an XT T-connector) a current signal can be passed from the next detector – Alpa EcoWent XT or Alpa EcoDet XT. This signal is compared with the local value and a signal corresponding to a status of a higher priority is transmitted to the output (see Table 1).

    www.atestgaz.pl Star layout Within a gas detection system arranged according to the conventional architecture any individual detector is directly connected to a central control unit. Such a solution needs routing of great many cables to a single control unit, which makes installation of a system quite difficult and cost of cabling is pretty large.
