Assembly / Installation

The Message Diffuser product is attached through a wall with a 55 mm diameter hole.

The silicone gasket is placed between the housing and the wall to seal. The nut behind the wall allows the unit to be attached by hand tightening.

Operation

The product has up to 6 recorded messages.
At the power on, the indicator on the front panel is green.

To broadcast a message, a voltage of 24V must be applied to the input associated with the message, for example: 24V on pin n°1 of the M12 connector for the broadcast of message n°1.

Message number	Pin number M12
1	1
2	3
3	4
4	5
5	6
6	8

While the message is being broadcast, the light on the front panel turns red.

The message is played as long as the 24V voltage is maintained on the input.
The message can be repeated up to 10 times if the command is maintained. At the end of the broadcast, the LED flashes red as long as the input is at 24V.

When the input is no longer controlled, the indicator turns green again.
If the 24V voltage is interrupted on the input during the broadcasting of the message, the message will be broadcast in its entirety.
At the end of the broadcast, the LED on the input turns green again.
