The Guardian ARFX5 is an addressable RF receiver. This personal alarm system component is housed within a metal IP65 rated weatherproof enclosure, designed specifically to provide coverage for external areas such as car parks, patios and gardens, or to provide back up for the infra red receivers inside a building. The installation and operation of this unit is similar to that of the AIRX3 External IR Unit.
The RF range can be affected by many factors including the weather and local conditions (e.g. location of buildings, large metal objects, cars, vans, chain link fences etc) and it is strongly recommended that a site survey is done to ascertain the correct number and locations of ARFX5 units required.
