With the Homematic IP Combo Signaler, a variety of signaling options with optical and acoustic output can be realized within the Homematic IP system – for example, as a doorbell, passage detector, or status indicator, such as monitoring the opening status of windows when leaving the house. Note: This is a kit that needs to be assembled! Individual sounds, whether voice announcements, sound sequences, or melodies/songs, can be easily stored as MP3 files on a microSD memory card and can then be triggered and played by various transmitters, sensors, etc. The high-quality speaker configuration ensures excellent sound and good speech intelligibility. Optical signals in different colors can be output independently of the sound on the light frame with an upward fading light effect. This allows for a wide range of signaling tasks to be accomplished, and even people with hearing impairments can be reliably notified through the various optical output options, such as when used as an optical doorbell in conjunction with the HmIP doorbell button. The combo signaler can be used for both battery-operated mobile use and stationary operation with power supply. This means you can take it with you in battery mode wherever you are, for example, into the garden. Combo signaler for acoustic and optical messages. Up to 250 acoustic messages in the form of MP3 files (CBR, VBR, ABR) with bit rates of up to 320 kBit/s can be retrieved from the microSD card. Optical display using RGB LEDs in the surrounding light frame with an upward fading light effect (7 colors including white selectable). Can be operated stationary via an external power supply or mobile with batteries. Thanks to the integrated weekly program in the device, time-controlled messages are possible.
