Run your GSM intercom or Z4 Controller if the power fails...
This Battery back up kit suits SimEntry Z4 GSM controllers only.
The battery fits neatly inside the Z4 enclosure (see image) and the seperate 14V battery charging power supply runs the Z4 controller and trickle charges the battery.
Charging is regulated by the Z4 controller and also monitered so when the mains power fails, the controller will send an SMS alert. As the battery level decreases, the Z4 will send SMS alerts at set intervals to indicate the battery level.
When mains power restores, Z4 will send a power restored SMS alert also with the battery level.
