Ajax 6V PSU power supply board for Hub 2 and Hub 2 Plus

The security alarm system is a key element of the premises security system. It is important that this security system works without failures and includes video surveillance, motion sensors, fire sensors, etc. The most common option for providing a security system with power is to connect devices to the electrical network, but in the event of an emergency power outage or interruptions, the object will remain unguarded. In order to avoid the occurrence of such situations, it is necessary to install an uninterruptible power supply unit for a security alarm. The use of this device guarantees object protection, which will not depend on the operability of the power supply line.

What functions does the power supply perform for alarm

  • The power supply for the alarm system supports the operation of the security system when the voltage drops in the network.
  • Protects the safety system from surges and increases in current consumption, and the resulting overloads of the output circuit.
  • Automatic transition to power supply from the battery of the unit, in case of a power outage.
  • Protects the alarm from output voltage surges above 16 Volts.
  • Protects the burglar alarm battery from being completely discharged.

The principle of operation of the Ajax 6V PSU power supply board

The use of a 6V PSU power supply board for Hub 2 and Hub 2 Plus protects the alarm from power surges in rooms with unstable power supply. With the help of a power supply unit, the hub and repeaters are connected to the low-voltage electrical networks, and the board itself is installed inside the case of the required device. The 6V PSU power supply for the Hub 2 and Hub 2 Plus control panels is capable of operating from an external battery for several years, without connecting the protected object to the electrical network. With the help of the power supply for the alarm system, the protection of the premises in an emergency condition is ensured. Installing the power supply will be advisable in rooms that will not be used for a long time. Such a system in combination with video surveillance will be able to warn about the penetration of intruders into the protected area. The device is only compatible with Hub 2 and Hub 2 Plus. The power cable is connected to the unit using a standard size plug. The 6V PSU also comes with a terminal adapter. The power supply board is installed inside the alarm control panel housing, in place of the 110/230 V power supply, which is pre-installed in the device. When using the Ajax 6V PSU power supply board, the security system can be installed even on objects that are in motion, such as mobile stalls or cars. The main features of the Ajax 6V PSU power supply board When installing the board, please note that power consumption depends on the following parameters:
  1. battery self-discharge current;
  2. stability of mobile communications;
  3. the number of currently active modules;
  4. temperature in the room where the alarm control panel is installed;
  5. battery capacity.
