Indendørs sirene SONOFF SenseGuard Zigbee

SONOFF SenseGuard Zigbee indoor siren

The SONOFF SenseGuard SNZB-09P is a smart Zigbee indoor siren that helps enhance the security of your home, garage, store, or other spaces. The device emits a loud alarm of up to 105 dB, offers customizable audio and visual alerts, and can work with other Zigbee devices to create an automated threat response system. With a choice of different alarm modes and integration with sensors and cameras, the siren allows you to tailor the alert method to a specific situation.

Loud alarm and flexible alert settings

The siren ensures effective notifications with an audible alarm reaching up to 105 dB. Users can select one of the available volume levels and customize the device’s operation to suit their needs. SONOFF SenseGuard also offers 10 built-in alarm sounds that can be assigned to different events or zones, making it easy to quickly identify the type of alert. Additionally, the device allows you to use sound only, light only, or a combination of both forms of signaling.

Zigbee smart security system

Zigbee 3.0 IEEE802.15.4 communication allows you to connect the siren to other smart home components, creating a cohesive security system. When paired with compatible Zigbee sensors and cameras, the device can automatically respond to detected events by triggering an alarm at the appropriate time. You can create security scenarios in which the siren activates, for example, upon detecting an open door or window, a water leak, motion, or the presence of an unauthorized person.

Dual power supply and reliable operation

SONOFF SenseGuard is equipped with two power sources, allowing it to continue operating even during power outages. The device uses a 5 V ⎓ 1 A USB-C power supply and a built-in 600 mAh battery, which provides up to 300 days of operation in silent mode. Once power is restored via the USB-C cable, the battery automatically begins charging, ensuring the siren remains ready for action.

Quick setup and convenient operation

Adding the siren to the system is simple and is done using the eWeLink app and a compatible Zigbee gateway. Just download the app, scan the QR code on the device, select a previously added Zigbee hub, and wait for the pairing process to complete. Once connected, you can manage the device’s settings and customize the alarm’s behavior to suit your needs.

Protection in various situations

Its versatile integration capabilities allow SONOFF SenseGuard to serve as the central component of an alert system in many scenarios. When paired with a water leak sensor, it can alert you to a flood risk; with a door/window sensor, it can respond to a door or window being opened; and with a motion sensor or camera, it can trigger an alarm upon detecting unauthorized activity. This solution allows you to create a customized security system for your home, office, store, or garage.

Compact design for indoor installation

The ABS plastic housing combines compact dimensions of 81 × 81 × 35 mm with a lightweight design weighing 106 g. The siren is designed for indoor use and can communicate with Zigbee devices at a distance of up to 100 m in open space. An operating temperature range of 0°C to 45°C and resistance to relative humidity of 0–90% (non-condensing) ensure stable operation under typical household conditions.
