The PDS-PRM presence detector switches are designed to provide automatic control of
lighting, heating or ventilation loads. They detect movement using a PIR sensor and
turn the load on. When an area is no longer occupied the load will switch off after an
adjustable time out period.
An internal light sensor provides additional energy saving in lighting applications. When
an area is occupied lighting is only switched on when the level of natural light is below a
preset level.
A selectable security mode switches the lights on for a period of 2 hours when it gets
dark, regardless of occupancy, to give the impression of a building being occupied.
The PDS-PRM/S comes with longer mounting screws and countersunk holes on the
cover plate. This is to allow the installer to secure the unit and cover plate with external
screw fixings.
