0312-PS1-T3 Sounder Issue 1.2, 200902
Operation:
The panel Bell circuit connects to the
PS1-T3
Sounder as shown below.
Bell terminals ‘+’ and ‘-’ connect to the corresponding Sounder ‘+’ and ‘-’ terminals.
If the Bells are not active, the panel monitors the Bell circuit by applying a negative
voltage to the
PS1-T3
‘+’ terminal. The quiescent current drawn by the
PS1-T3
under
this condition is less than 0.4
µ
A.
When the panel Bell circuit activates, the panel Bell circuit voltage reverses (applying
positive voltage to the
PS1-T3
‘+’ terminal), sounding the
PS1-T3
. The ‘T3’ tone is
generated if the ‘Alert’ terminal is open or J3 link not fitted. If the ‘Alert’ terminal of the
PS1-T3
is connected to 0V (negative) or the J3 link is fitted, the ‘AS2220’ tone is
generated instead.
