This means:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Normal State<\/strong>: The lock is continuously powered, generating a strong magnetic force that holds the door securely closed.<\/li>\n\n\n\n<li><strong>Unlock State<\/strong>: When the outdoor station verifies the credentials, it&nbsp;<strong>briefly cuts off<\/strong>&nbsp;the power supply to the magnetic lock. The magnetic force disappears, and the door is released.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding this&nbsp;<strong>&#8220;Normally Closed (NC)&#8221;<\/strong>&nbsp;mechanism is the core of successful wiring. The magnetic lock is typically connected to the outdoor station via its relay contacts (such as NC and COM \u2013 Common terminal).<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 id=\"preparation-before-wiring\" class=\"wp-block-heading\">\ud83d\udee0\ufe0f Preparation Before Wiring<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Before you start wiring, ensure you have the following components ready:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>IP Apartment Outdoor Station<\/strong>: The core of the system, responsible for verifying identity and sending the unlock signal.<\/li>\n\n\n\n<li><strong>Magnetic Lock<\/strong>: Ensure its operating voltage (usually 12V DC) is compatible with the outdoor station or power supply.<\/li>\n\n\n\n<li><strong>Dedicated Access Control Power Supply<\/strong>: Recommended to provide stable, independent power to both the outdoor station and the magnetic lock.<\/li>\n\n\n\n<li><strong>Cables<\/strong>: Prepare sufficient power and signal cables. It is recommended to use cables of 0.5mm\u00b2 or larger.<\/li>\n\n\n\n<li><strong>Exit Button (Optional)<\/strong>: For manually unlocking the door from the inside.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 id=\"step-by-step-wiring-guide\" class=\"wp-block-heading\">\ud83d\udcdd Step-by-Step Wiring Guide<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The wiring logic of the entire system is clear and straightforward, centering around two main lines:&nbsp;<strong>&#8220;Signal Control&#8221;<\/strong>&nbsp;und&nbsp;<strong>&#8220;Power Supply&#8221;<\/strong>&nbsp;. Below is a standard wiring procedure:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Step 1: Connect the Access Control Power Supply<\/strong><\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>Connect the 220V AC input (L, N) of the power supply to the mains electricity.<\/li>\n\n\n\n<li>Connect the 12V DC output (+12V, GND) of the power supply to the power input terminals of the outdoor station. This provides the operating power for the outdoor station.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Step 2: Connect the Outdoor Station to the Magnetic Lock (Critical Step)<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is the most crucial step, using the outdoor station&#8217;s relay to control the on\/off switching of the power supply to the magnetic lock.<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>On the outdoor station, locate the terminals for controlling the door lock, typically labelled&nbsp;<strong>NC<\/strong>&nbsp;(Normally Closed),&nbsp;<strong>COM<\/strong>&nbsp;(Common), and&nbsp;<strong>NO<\/strong>&nbsp;(Normally Open).<\/li>\n\n\n\n<li>For a &#8220;fail-safe&#8221; (power-to-lock) magnetic lock, you should use the&nbsp;<strong>NC<\/strong>&nbsp;und&nbsp;<strong>COM<\/strong>&nbsp;terminals.<\/li>\n\n\n\n<li><strong>Magnetic Lock Power Positive<\/strong>: Connect the red wire (positive) of the magnetic lock directly to the&nbsp;<strong>+12V<\/strong>&nbsp;output terminal of the access control power supply.<\/li>\n\n\n\n<li><strong>Magnetic Lock Power Negative<\/strong>: Connect the black wire (negative) of the magnetic lock to the&nbsp;<strong>COM<\/strong>&nbsp;terminal of the outdoor station.<\/li>\n\n\n\n<li><strong>Connect the Control Signal<\/strong>: Use a wire to connect the&nbsp;<strong>NC<\/strong>&nbsp;terminal of the outdoor station to the&nbsp;<strong>GND<\/strong>&nbsp;(negative) terminal of the access control power supply.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Step 3: Connect the Exit Button (Optional)<\/strong><\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>Connect the two wires of the exit button to the&nbsp;<strong>GND<\/strong>&nbsp;und&nbsp;<strong>PUSH<\/strong>&nbsp;(or open signal) terminals on the access control power supply. The button wires are non-polarity.<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 id=\"configuration-and-testing\" class=\"wp-block-heading\">\u2699\ufe0f Configuration and Testing<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">After completing the wiring, basic configuration and functional testing are required.<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Power-On Check<\/strong>: Verify that all devices are powered on correctly.<\/li>\n\n\n\n<li><strong>Funktionstest<\/strong>:\n<ul class=\"wp-block-list\">\n<li><strong>Card\/Password\/Face Unlock<\/strong>: Authenticate at the outdoor station. Upon successful verification, the magnetic lock should briefly release, and the door should open.<\/li>\n\n\n\n<li><strong>Indoor Monitor Unlock<\/strong>: Test unlocking the door via the indoor monitor&#8217;s unlock button.<\/li>\n\n\n\n<li><strong>Exit Button Unlock<\/strong>: Press the exit button to ensure the door opens normally.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Parameter Adjustment<\/strong>: If the unlock time is too short or too long, adjust the &#8220;Unlock Delay&#8221; parameter on the outdoor station or the access control power supply.<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 id=\"troubleshooting-common-issues\" class=\"wp-block-heading\">\u26a0\ufe0f Troubleshooting Common Issues<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Door Cannot Open<\/strong>:\n<ul class=\"wp-block-list\">\n<li>Check if the NC and COM terminals on the outdoor station show a change in state (continuity) when credentials are verified.<\/li>\n\n\n\n<li>Verify that the magnetic lock is receiving the correct on\/off power signal.<\/li>\n\n\n\n<li>Check if the access control power supply is functioning correctly.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Door Cannot Lock<\/strong>:\n<ul class=\"wp-block-list\">\n<li>Check if the magnetic lock is receiving power; confirm the power cable connections.<\/li>\n\n\n\n<li>Check for foreign objects or misalignment on the magnetic lock&#8217;s contact surface.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Wiring Precautions<\/strong>: Immer&nbsp;<strong>disconnect the power<\/strong>&nbsp;before performing any wiring operations to ensure safety. If unsure, consult a professional.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 id=\"summary\" class=\"wp-block-heading\">\ud83d\udc8e Summary<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Connecting an IP apartment outdoor station to a magnetic lock essentially involves using the&nbsp;<strong>dry contact signal<\/strong>&nbsp;from the outdoor station&#8217;s relay to control the&nbsp;<strong>on\/off switching<\/strong>&nbsp;of the power supply circuit to the magnetic lock. By understanding the core concepts of &#8220;fail-safe (power-to-lock)&#8221; and &#8220;Normally Closed (NC),&#8221; and by following the clear wiring logic, the entire process becomes straightforward and manageable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For specific device manuals or unique issues, it is advisable to consult FARHD&#8217;s official product documentation or contact their technical support directly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udce7&nbsp;<strong>E-Mail<\/strong>:&nbsp;info@farhd.com<br>\ud83c\udf10&nbsp;<strong>Website<\/strong>:&nbsp;<a href=\"https:\/\/farhd.com\/de\/\" target=\"_blank\" rel=\"noreferrer noopener\">www.farhd.com<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Connecting an IP apartment outdoor station to a magnetic lock is a critical step in building a modern smart access control system.
