Power Supply
The Siren is powered by AC power. Plug the Siren into a power socket to activate the Siren. The Siren will enter normal operation mode. For SRV-23B, there is a rechargeable battery inside the Siren that serves as a backup in case of a power failure. During normal operation, AC power is used to power the Siren and at the same time recharge the battery.
Low Battery Detection
After AC power failure, the Siren will transmit a Low Battery signal to the Control Panel when low battery voltage is detected. To restore battery, re-plug AC power into the power socket. After 12 hours, the Siren will transmit a low battery restored notification to the Control Panel.

AC Failure Detection
Whenever the Siren is removed from the power socket, the siren will transmit an AC fault signal to the Control Panel to notify users of the situation. The Siren will then switch to its internal battery for power supply.
When the Siren is re-plugged into the power socket, it will send an AC power restore signal to the Control Panel.
Supervision
The Siren transmits a supervisory signal to the Control Panel once every 30-50 minutes during normal operation.
If this signal is not received with programmed duration, the Control Panel will indicate on its screen that the particular Siren is experiencing an out-of-order problem.
Getting Started
Plug the Siren into the power socket. The LED will flash once to indicate it is now in normal operation mode.
Put the Control Panel into learning mode.
Press the button on the Siren once to transmit a learn code to the Control Panel. The Siren will emit one beep, and the LED will light up to indicate the siren is now in learning mode.
The learning mode of siren will last as long as 1 minute.
If within 1 minute the siren receives acknowledgement from the Control Panel, the Siren will emit four beeps and turn off LED. Learning is now completed.
If within 1 minute the siren receives acknowledgement from the Control Panel and emits only one beep, it means the Siren has been previously learned into the Control Panel.
If after 1 minute the Siren does not receive acknowledgement from the Control Panel, the siren will emit 5 beeps and turn off LED. Learning is unsuccessful. Please repeat the learning process.
