DANLERS - Model CESFA PIR -Ceiling Surface-mounted PIR Absence Switch

Ceiling surface-mounted PIR absence switch. When someone enters a room the lights are turned on using a wall switch. When the occupant leaves the room or area of detection the CESFA PIR automatically switches the lights off after a pre-selected time. The override OFF function allows the occupant to turn the lights off from the wall switch (while the CESFA PIR is in the ON state) without waiting for the pre-selected time lag to time out. The lights can be switched back ON by operating the wall switch in the usual way.
