Since the AR-727HB-RAY is a two door controller utilising RS485 technology, connections for two RS485 proximity readers have been provided on the main connection circuit board in the unit as well as terminals for two locks. The built-in power supply has a maximum output of 3 amps for the locks. If a standby battery is required, this must be ordered separately as must the gsm modem. We recommend the use of the AR-737HB-RAY proximity reader, which can be mounted in a number of ways - please check the section on this product. The light grey steel box is lockable with a security key. This product was designed to provide installers with a quick and convenient method of installation.
Please Note: This system may be supplied in an alternative metal case with a different power supply as the EAR-727HB-RAY.
Safety Notice No. N2111
Please note that although the earth terminal on a 240V switch mode power supply should always be connected to the earth terminal in any metal enclosure in which is may be mounted, and thereby to a general earth connection, it is still possible to sustain a mild electric shock in the region of 95v at 170µA from the OV terminal of the power supply if it is not also connected to earth. Although this would not normally be regarded as more than uncomfortable, it could be extremely dangerous if it was sustained by an operative either working up a ladder or with a heart condition. We recommend, therefore, that unless there are good technical reasons for not doing so the OV terminal should always be connected to earth.
This is also important for technical reasons in order to ensure stability throughout any system or network utilizing this type of power supply.
