Dahua- ARA12-W2

  DAHUA WIRELESS INTRUSION ALARM ARA12-W2  

FEATURES

• Signal Strength Detection & Two-Way Wireless Communication

• The siren monitors its wireless link quality and uses two-way communication so the panel and siren can verify connection, enhancing system reliability.

• Low-Battery Alarm & Test Mode

• Built-in battery-level monitoring triggers a low-battery alarm, and the device includes a test mode so installers can validate functionality prior to commissioning.

• Temperature Monitoring

• The unit measures ambient temperature and reports it, allowing the siren to be used in applications where environmental conditions are important.

• Frequency-Hopping & AES-128 Encryption

• Uses a frequency-hopping spread-spectrum wireless protocol and AES-128 encryption to reduce interference and secure communications against tampering.
