Gira 2399 02 Operating Instructions Manual page 5

Presence detector and motion detector 360° compact
– Indoor ceiling mounting, surface-mounted
Product characteristics
– 2-point light control
– Functions settable with IR remote controls
– Restriction of the detection field by switching off individual sensors or push-on
cover
– Operation with IR remote control, 2-wire extension or push-button
– Teach function for adjustment of the brightness threshold, in combination with
IR remote controls
– Switch-off warning
– Short time operation, e.g. to activate acoustic signal encoders
– Display LEDs
– Presence simulation
– Function as twilight switch
– Dynamic run-on time
– Extension of the detection field through parallel switching of multiple devices
The extension of the detection field with 3-wire extensions is not possible.
Automatic operation
The device detects heat motions of people, animals and objects.
– The light is switched on if a person enters the detection field and the bright-
ness threshold is below the set brightness threshold.
The run-on time restarts with each detected motion.
– The light is switched off when it is no longer required because:
no more movement is detected in the detection field and the run-on time has
elapsed or the ambient light is bright enough.
The switch-off brightness is calculated from the set brightness threshold and
the connected light.
To avoid brief shading from causing switch-off, switch-off only takes place
when the set run-on time has elapsed. The run-on time does not restart on
movement detection for as long as the switch-off brightness is exceeded.
The minimum switch-off brightness is 100 lux, even if a lower value is set.
To avoid any switch-on caused by a cooling lamp, no movement signals are evalu-
ated for a brief lockout time after switching off. The motion detector adjusts itself to
the ambient conditions to keep the time as short as possible.
Short-time operation
If motion occurs, then a short pulse of approx. 0.5 seconds is triggered depending on
the brightness. The pulse is cyclically repeated as long as motions are detected.
