Battery:

• The device is equipped with a high-capacity lithium battery with an impressive lifespan of 20 years on the shelf.
• Intelligent software is employed to conserve battery life. In the event of an alarm persisting for longer than 60 minutes, the IS-AB goes into a lowered output mode with only a 20% duty cycle. This allows the battery to last for almost a month under continuous alarm conditions.
• The alarm box includes a low battery signal, providing a warning when it’s time to replace the battery.
• The battery replacement process is simple, involving plugging in a replacement, and it can be done in a hazardous location, ensuring ease of maintenance.

Other points:

• Operating temperature: -40ºC to 60ºC, suitable for outdoor use.
• Low temperatures may halve battery life (details on the website).
• Low battery signaled by rapid 5-second beeping every 30 seconds.
• Second sensor (LS2) has a slower beeping/flashing pattern than the first.
