Cable connection instruction:
1. Black cable: Connects the black cable to ground of your intelligent power supply.
2. Red cable: Connects the red able to NC terminal of your intelligent power supply.
ATTENTION 1: Please note that this electric strike can connect directly to access control unit such as   listed below, but we do not suggest buyer to do so because it will shorten the lifespan of your access control unit due to high current passing through the electric strike. Instead, you should connect the strike directly to an intelligent uninterruptible power supply (UPS)  that has NC/NO output. Make sure your UPS is "intelligent" meaning that it has NC or NO power output and can receive "door open" signal input from your access control.
ATTENTION 2: Normally Opened (NO) or Fail-secure rated electric strike remains locked during loss of power supply. Normally Closed (NC) or Fail-safe rated electric strike requires power to stay locked. When power is lost (such as a blackout), NC or fail-safe Electric Lock Strikes will remain unlocked until power is restored. Electric Strike that is NO rated may not be compliant with your local building / fire safety code. We personally feel that NC rated electric strike is safer. Buyer should check with their local safety code before making decision to buy a NC or NO rated electric strike. In order to ensure that power supply is not intentionally lost (in the event of theft/burglary), we suggest buyer to buy an Uninterruptible Power Supply shown below.
