Power Supply and Battery Backup Unit
· System Status Lights
The power supply and battery backup unit powers the network termination device also known as the NTD. It also contains a battery backup to provide emergency power to a standard corded phone using a working voice port. The battery backup will last approximately five hours in the event of an extended blackout. Check with Aconnect to see if this applies to you. The lights indicates that your system is working properly, check the user guide to find out what you see when your power supply and battery backup unit is connected properly and functioning normally. The system standard light should be green and the battery power and battery replace lights both should be off.
· Emergency Power Activation
During an extended blackout the power supply and battery backup unit will switch off when about half of the battery charge still remains, saving about two to three hours charge which can be used later for emergency calls. At this point the battery power indicator will be flashing and the power supply and the battery backup unit will sounds a warning. Before the power supply and battery backup unit turns off to preserve the remaining charge the alarm will stop. In an emergency, this is how you access the remaining charge to make a call using the voice port. Press and hold the blue battery emergency use button for two seconds until the power supply and battery backup unit beeps once and the four lights flash, be aware that after the battery is completely flat the battery emergency use button will not work again until power has been restored and the battery is recharged or replaced.
· Alarms
So what alarm sounds are you likely to hear? The system will beep once if there’s a loss of mains power, the system will beep once every 15 minutes if the battery needs replacing. You hear the beeps, you will hear beeps four times a minute if there’s less than half the battery charge remaining. Please and hold the blue alarm silence button for one to two seconds to silence the alarm for 24 hours. If the battery replace light is on or flashing red the battery must be replaced as soon as possible. Batteries are available at any specialist battery retailer. Always keep your power supply unit connected unless you need to replace the battery or Aconnect asks you to unplug the unit. Keep in mind the life of your battery will be reduced if you turn the mains power on and off regularly or leaves the mains power disconnected for an extended period of time. You’ll be pleased to know the power used by the system is minimal on average less than a 15 watt light bulb.
The system status lights tell you what is happening with your equipment. Using the emergency power activation button will give you about two to three hours charge which can be used for emergency calls using a standard, non-powered telephone service connected to an in service voice port. The alarms will sound to tell you what state your battery is in.
