They mount on the surface of the door rather than inside it, making them easier to install and retrofit\u2014especially in older buildings or glass doors. When combined with a 2-wire video door phone, they create a seamless entry experience: residents see and speak with visitors, then unlock the door with a card, a button on the indoor monitor, or a tap on their smartphone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The FARHD 2-wire video door phone system is designed for easy integration with electric rim locks. The system uses a single pair of wires to carry power, video, audio, and control signals between the outdoor station and indoor monitor\u2014and includes a relay output specifically for lock control.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This guide explains how to connect an electric rim lock to a FARHD 2-wire video door phone system, and how the three unlock methods work.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 id=\"understanding-electric-rim-locks\" class=\"wp-block-heading\">Understanding Electric Rim Locks<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Before wiring, it is important to understand the type of electric rim lock you have, as this affects how it connects to the relay.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What is an electric rim lock?<\/strong><br>An electric rim lock is a locking device that mounts on the surface of the door. It uses an electric solenoid or motor to control the latch mechanism. When powered, the lock releases; when power is removed, it returns to its locked state (or vice versa, depending on the model).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Two main types:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th class=\"has-text-align-left\" data-align=\"left\">Type<\/th><th class=\"has-text-align-left\" data-align=\"left\">Operation<\/th><th class=\"has-text-align-left\" data-align=\"left\">Power Required to Unlock?<\/th><th class=\"has-text-align-left\" data-align=\"left\">Typical Use<\/th><\/tr><\/thead><tbody><tr><td><strong>Fail-secure<\/strong><\/td><td>Locked by default; requires power to release<\/td><td>Yes \u2013 power is applied to unlock<\/td><td>Most common for rim locks<\/td><\/tr><tr><td><strong>Fail-safe<\/strong><\/td><td>Unlocked by default; requires power to lock<\/td><td>No \u2013 power is removed to unlock<\/td><td>Used in fire safety applications<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">For most residential and commercial applications, <strong>fail-secure electric rim locks<\/strong> are used. These require a power supply to release the latch. The relay on the video door phone acts as a switch to control that power.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Important:<\/strong> The relay on a video door phone is typically a dry contact (NO\/COM). It does not supply power to the lock. A separate power supply for the lock is required. Electric rim locks typically operate at <strong>12V DC<\/strong>.<\/p>\n<\/blockquote>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 id=\"system-components-you-will-need\" class=\"wp-block-heading\">System Components You Will Need<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">To connect an electric rim lock to a 2-wire video door phone, gather the following:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th class=\"has-text-align-left\" data-align=\"left\">Component<\/th><th class=\"has-text-align-left\" data-align=\"left\">Purpose<\/th><\/tr><\/thead><tbody><tr><td><strong>2-Wire Video Door Phone Kit<\/strong><\/td><td>Includes outdoor station and indoor monitor<\/td><\/tr><tr><td><strong>Electric Rim Lock<\/strong><\/td><td>Fail-secure type recommended (12V DC)<\/td><\/tr><tr><td><strong>Power Supply for Lock<\/strong><\/td><td>Matches lock voltage and current (e.g., 12V DC, 1A)<\/td><\/tr><tr><td><strong>2-Core Cable<\/strong><\/td><td>For 2-wire connection between outdoor station and indoor monitor<\/td><\/tr><tr><td><strong>2-Core Cable for Lock<\/strong><\/td><td>For connecting lock to relay and power supply<\/td><\/tr><tr><td><strong>Tools<\/strong><\/td><td>Wire strippers, screwdrivers, multimeter<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 id=\"wiring-diagram-overview\" class=\"wp-block-heading\">Wiring Diagram Overview<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The basic wiring for connecting an electric rim lock to a 2-wire video door phone is as follows:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">text<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">[Power Supply +] ----&gt; [Electric Rim Lock +]\n[Electric Rim Lock -] ----&gt; [COM terminal on Outdoor Station]\n[Power Supply -] ----&gt; [NO terminal on Outdoor Station]<\/pre>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How it works:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>When the relay is not triggered, NO and COM are open. No power flows to the lock, and the door remains locked.<\/li>\n\n\n\n<li>When an unlock command is sent (via card, indoor monitor, or app), the relay closes the circuit between NO and COM. Power flows from the supply, through the lock, and back to the supply. The lock releases, and the door can be opened.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This configuration works for <strong>fail-secure<\/strong> rim locks. For <strong>fail-safe<\/strong> locks, you would use the NC terminal instead, and the logic is reversed (power removed to unlock).<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 id=\"step-by-step-connection-guide\" class=\"wp-block-heading\">Step-by-Step Connection Guide<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Step 1: Mount the Outdoor Station and Indoor Monitor<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Mount the outdoor station at the entrance at a suitable height (typically 1.4\u20131.6 metres).<\/li>\n\n\n\n<li>Mount the indoor monitor in a convenient indoor location.<\/li>\n\n\n\n<li>Run the 2-core cable between them.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Step 2: Connect the 2-Wire Cable<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Connect the two wires to the 2-wire terminals on the outdoor station (no polarity).<\/li>\n\n\n\n<li>Connect the other end to the 2-wire terminals on the indoor monitor.<\/li>\n\n\n\n<li>Power the indoor monitor with the provided adapter. The indoor monitor supplies power to the outdoor station.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Step 3: Connect the Electric Rim Lock<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Locate the relay output terminals on the outdoor station. They are usually labelled <strong>NO<\/strong> (Normally Open), <strong>COM<\/strong> (Common), and <strong>NC<\/strong> (Normally Closed).<\/li>\n\n\n\n<li>Connect the <strong>negative (\u2013)<\/strong> wire of the lock power supply to the <strong>NO<\/strong> terminal.<\/li>\n\n\n\n<li>Connect the <strong>negative (\u2013)<\/strong> wire of the lock to the <strong>COM<\/strong> terminal.<\/li>\n\n\n\n<li>Connect the <strong>positive (+)<\/strong> wire of the lock to the <strong>positive (+)<\/strong> wire of the power supply.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Note:<\/strong> Some electric rim locks are polarity-sensitive.
