Contact detector prepared for KA
or KCtr by smartbox connection.
• For direct connection to KA/KCtr
• Mounted on the ceiling (surface)
• Size: 60 x 85 x 58mm
Description
This kind of detectors are mounted on the ceiling and detect the presence of smoke in the room where are located.
• Optical detectors are designed to be placed in areas where there is usually the presence of smoke, ie. hallways, rooms, etc.
• They are also installed when you cannot install thermovelocimetric detectors, being areas where although there is smoke,
you cannot wait, in case of a fire, for the temperature to rise above the critical thermovelocimetric value.
Configuration using Development System (SIDE)
• 2 programmable scenes for activation and deactivation of the BUSing® sensor (reference: DH-BUS).
• Up to 60 programmable BUS events for each scene
.
