SR-740 PG2 is a two-way wireless outdoor siren (IP55). It provides the perfect security solution for home owners with a PowerMaster system who are looking for an affordable and easy to install outdoor siren. It excels in offering cabling-free installation and optional extended time between battery changes.

SR-740 PG2 uses Visonic's ground-breaking PowerG technology, which combines several field-proven, advanced technologies and the highly reliable AES encryption method. The combination of technologies delivers an extended transmission range, far greater than the industry standard - enabling a very large distance between the siren and the control panel. It also provides an extended battery life that makes it easy and affordable to maintain.

The sleek design ensures the SR-740 PG2 siren is clearly visible from almost every angle. This makes it highly effective at alerting and deterring potential intruders, while maintaining the clean external look of any building.
