The SR-740 PG2 is a two-way wireless outdoor siren (IP55), providing the ideal security solution for homeowners with a PowerMaster wireless intrusion alarm system who need an inexpensive, easy-to-install siren. outdoors. It excels in offering cable-free installation and extended battery life.

The SR-740 PG2 siren uses Visonic's innovative PowerG technology, which combines various advanced and field-proven technologies, with the highly reliable AES encryption method. This combination of technologies provides an extended transmission range, much greater than the industry standard, allowing a great distance between the siren and the control panel. It also provides extended battery life, which makes it easy and inexpensive to maintain.

The fully supervised, two-way communication of the siren with the control panel provides visual and audible notifications of intrusions, fire alarms, low battery and communication interruptions.
