The SA840 Addressable Indoor Siren is designed for audio\/visual warning in an addressable system. It is ideal for providing warnings in fire and security applications of buildings such as hotels and residences during emergency situations. It emits a loud warning to ensure the evacuation of building occupants. SA840 series sirens can be connected by the loop in the addressable fire alarm system. In addition, in case of a short circuit in the loop line, it isolates the next part of the loop line using the internal isolator. Any address between 1 and 250 can be assigned to the siren. When activated, the SA840 initiates an audible alert; it also provides a visual alert with a red indicator. These indicators have a 360\u00b0 field of view. The device can be reset by de-energizing the power supply<\/p>\n","protected":false},"excerpt":{"rendered":"
