LOW BATT output
Terminal no. 10
This open collector output collects all low battery events from the memorized sirens. When a low battery transmission
arrives from one of the memorized sirens, the output is switched to low level. The display and the
low battery LED DL3
display and memorized the event. This condition persists until the flat batteries of the siren are replaced.
Button P1
This button allows to transmit constantly a radio signal to be memorized on the outdoor sirens.
In this phase, the display shows the letter “t” flashing.
During programming it is used to delete a siren code. During power-on (first start-up) it generates a new 16-bit code.
In this phase it displays horizontal dashes in continuous rotation.
Button P2
This allows to access programming, select the 8 zones to be memorized and to exit programming.
