We have power supplies of various amperage ratings for connection to AI devices and other accessories. In addition, the Falcon XTHardware controller used in conjunction with StorLogix software to control AI Devices at a site. has a built-in supply that can power some AI devices. All PTI power supplies have battery backup.

|Hardwired Door Alarm MuxDoor Alarm Multiplexers take multiple inputs from individual door contacts and convert them to a single output back to the controller. Camera Multiplexers are similar in that they take multiple inputs from different cameras and create a single output back to the recorder. (16 - 96 Ch)

- When powering other equipment (such as a proximity reader or pinhole camera) from an AI device, be sure to consider the current draw specifications from that equipment as well.
- For best results in most situations, do not exceed 75% of the amperage load on any given power supply.
- Also, remember that line length, wire condition, splices, number of devices connected, humidity, temperature, and other factors cause voltage drop; so do not assume that three 300 mA devices can be powered from one 1A power supply. Always make it a point to check the voltage at every device once the site is completely up and running to ensure that no device is below 12V at any time.
- For example – 2A power supply (2250 mA max. load) can support seven keypads equaling 2100 mA OR four keypads and two 8-channel relay boards totaling 2200 mA. If you wanted to add any other devices, you would have to move to the next larger power supply OR add an additional 1A power supply. If you are unsure, always use the next size larger remote power supply.
- It is always better to have more available amperage than less as an AI device will only draw to its capacity and no more.
- Always power sirens, maglocks, and door strikes from power supplies that are separate from the ones that power AI devices. Never use the controller or any remote power supply that is connected to an AI device to power these types of devices (sirens, maglocks, door strikes) as they have significant amperage draw and can lock up the entire system. A remote power supply can be used to power these items in some cases, but it needs to remain separate from the AI devices.
Battery BackupAn electronic file containing historical events, data, and setup information for a site. This should be kept in a separate off-site location to allow the quick repair of a site in case of catastrophic data loss such as physical destruction of the computer or office, computer crash, employee error, etc. Calculation
- Battery backup time is equal to the current draw (amps) divided by the amp hour rating of the battery.
- For example: if the system draws 2 amps and the battery is rated at 4 amp hours; the battery backup should last for 2 hours if the battery is fully charged and all other conditions are right (4 ÷ 2 = 2). Certain external issues can influence this length of time, such as the age and condition of the battery, battery temperature, damage to the battery or power supply, power surges, and/or the level of charge in the battery.
- Also, each time the AI device is used while the AC power is out will reduce the total backup time as the current draw increases slightly when the keypad is in use.
