The Guardian AIRX3 is an addressable external infra red receiver unit. This component of the personal alarm system is housed within an IP65 rated weatherproof case, designed specifically to provide coverage for external areas such as courtyards, patios and gardens. The installation and operation of this unit is similar to that of the AIRX4 and AIRX7 units, with the addition of extra connections for external call and reset buttons.
All cable entry points are made through the cable gland at the bottom of the unit to ensure that no moisture ingresses into the electronics.
The design of the Guardian AIRX3 , along with the sun filter, means that it is immune to interference from sunlight. The unit should be mounted high on an external wall to prevent tampering. In the event of tampering with the AIRX3, the unit has a tamper switch built into it, which will alert the Display units.
As with all the Guardian addressable IR receivers, the unit is addressable. It has a removable jumper to disable the two colour reassurance LED which, when active, indicates that the unit is operational.
