.NOTE

(see electrical characteristics sheet)

Initial supply voltage (VSI) is the supply voltage required to start the tone ringer oscillating.

Sustaining voltage (Vsus) is the supply voltage required to maintain oscillation.

VTR and ITR are the conditions applied to trigger in to start oscillation for VSUS≤ Vcc ≤VsI

VDIS and IDIS are the conditions applied to trigger in to inhibit oscillation for VSI ≤Vcc

Trigger current must be limited to this value externally.
