The Mercury EL500 series animal immune detectors use digital technology to actually look at objects in the protected area and positively recognise them.They are able to tell the difference between an animal and a human over full area multiple zone coverage right down to floor level.

The Mercury EL500 series detectors are installed as simply as any other Pir there is only difference they recognise and ignore animals.

No microwaves, no masked lens, no tricky installation just digital immunity.

Can you Tell the difference

Most PIR’s fail to detect or give false alarms when the ambient temperature of a
room gets close or matches body temperature 37°C ( 98.6°F).

The 500 with an enhanced temperature compensation system designed for harsh environments, actually adjusts to ensure that the high levels of detection are maintained.

Ideal for use in CONSERVATORIES & KITCHENS
