Esser 804902 Non-Latching Conventional Fire Button Electronic Module

Shares the same electronic design as 804900; the difference is that the trigger element does not mechanically latch after being pressed. Thus the button returns to its initial position after test and drill without requiring special intervention. Connected to a conventional detection zone and makes the alarm visible via red LED. VdS approval is valid together with blue housing model number 704901; this distinction ensures the bill of materials is set up correctly from the start.
