Technical data
4.4 Lintel-mounted smoke switch GC 151
Lintel-mounted smoke switch GC 151
ID 142250
Functional principle
Scatter light, adaption of the alarm threshold, no alarm saving (self-
resetting as soon as there is no longer any smoke in the measuring
chamber)
Input voltage
24 V ± 0,5 V DC
Input current
maximum 15 mA
Installation position
Wall (lintel) installation, horizontal
Output hold-open device
Transistor output, short-circuit proof
Free-wheeling diode for inductive load, maximum 24 V, 200 mA
in the event of an alarm switch-off of the hold-open device for at least 4 s
Additional detectors
Connection of up to 3 ceiling-mounted detectors using 3-line technology
Line monitoring (can be switched off) using two terminating resistors
(43 kΩ each) at the end of the cable
Manual trigger switch
Line monitoring (can be switched off) using terminating resistor
(43 kΩ) at the end of the cable
Alarm output
Potential-free relay output, changer
maximum 24 V DC / maximum 1 A
Test button
The hold-open device is switched off as long as the key is pressed
(for at least 4 s)
Reset of the smoke switch by activating the button
Detector test
Alarm triggering: with test button or with test aerosol
Line monitoring may only be deactivated when used as a spare part in old systems without line monitoring
(ORS 141).
Switch the supply voltage off before changing the jumper setting (remove terminal clamp KL1).
The new jumper setting only becomes active after the mains voltage has been switched back on again.
