Class change on a Gent 4 zone fire alarm panel

[stranded]

The length of pulse is for the duration of the bells sounding, in schools say you wish to have a 4 secound bell for class change, then using a normal digi timer will only switch at 1 minute intervals, so a normal timer will give you a 1 minute bell ring. Using pulse timer you can set out contacts for 1 sec interval...so setting for 4 seconds gives the required bell duration.

Ahh, i see. Its good to learn more, im only starting out
