PRLM-CH3-AC-F1
3-channel relay controller F1
Introduction
PRLM-CH3-AC is a 3-channel Relay Switch that enables wireless operations of 3 separate connected devices, allowing users to remotely manage facilities inside and outside the home.
The Relay Switch is also equipped with the strain relief clamps for electrical and mechanical integrity and overall performance and safety.

4. LED indicator 1 5. LED indicator 2
6. LED indicator 3
The LED indicator 1/2/3 are used to indicate Relay Channel 1/2/3 status:
- LED 1 On/Off: Relay Channel 1 On/Off - LED 2 On/Off: Relay Channel 2 On/Off - LED 3 On/Off: Relay Channel 3 On/Off When powered on, all LEDs will flash for two times.
When in learning mode, all LEDs will flash slowly.
When learning is successful, all LEDs will flash for 3 times.

Specification
l Power Supply: 100 - 240V AC
l Supported Load Current (for each relay channel): 5A, 250VAC or 5A, 30VDC
l Stranded Wire: 14–22 AWG
l Operating Temperature: -10°C to 45°C (14°F to 113°F)
l Humidity: Up to 85% non-condensing
l Dimension: 110mm x 91mm x 28mm
Installation Environment 
l The Relay Switch should be installed indoors in a dry location.
l It is recommended to install the device in a fire resistant plastic gangbox.
l Do not install the device in a metal gangbox for optimization of RF range.
Caution
l All works on the device, including installation and maintenance, must be performed by a qualified and licensed electrician.
l To prevent electrical shock and/or equipment damage, disconnect electrical power at the main fuse or circuit breaker before installation and maintenance.
l Do not connect the device to loads exceeding supported load current.
Installation
Wire the Relay according to the instructions below.
1. Please turn off the power supply before connection.
2. Remove the top cover and remove the strain relief clamps.
3. Connect the L and N terminals of the power supply to the Line and Neutral terminals of PRLM respectively through the wiring hole.
4. Depending on the device you wish to control via Relay Channel 1, select NO terminal and wire Relay Channel 1 with the device through the wiring hole to establish Normal Open connection with device.
5. In the same way as step 4, connect Relay Channel 2/3 to other wired devices.
6. After completing the wiring, replace the strain relief clamps and the top cover. Turn on the power supply to power on the Relay Switch.
Getting Started
Step 1: Connect the power input to the Relay Switch according to Installation instructions above and power up the Relay Switch.
Step 2: Put the Control Panel into learning mode.
Step 3: Press and hold the Test button for 3 seconds to send a learn code.
Step 4: The three LEDs will start to flash slowly, indicating that the Relay Switch is in learning mode.
Step 5: Upon receiving acknowledgement from the Control Panel, the three LEDs will flash three times to indicate successful learning. The Relay Switch will then exit learning mode.
Note:After entering learning mode, the Relay Switch will not automatically leave learning mode unlesss it receives acknowledgement from the Control Panel, or unless the Test button is pressed.
Walk Test
To test whether the Relay Switch is able to communicate with the Control Panel:
l Put the Control Panel into Walk Test mode.
l Press the Test Button on the Relay Switch.
l The Control Panel should display if the Relay Switch is within the operation range (please refer to the operation manual of the Control Panel).
Mounting
l After you have finished the Walk Test, and you are satisfied that the device is able to communicate with the Control Panel in the chosen location, proceed to mounting.
l Disconnect the main power supply.
l Loosen the bottom fixing screw and remove the top cover of the Relay Switch.
l Use the holes on the base to mark mounting location on the wall.
l Drill holes into marked location and insert wall plugs if required, screw the base onto the mounting location.
l Replace the top cover and tighten the bottom fixing screw.
Operation
l After the Relay Switch is successfully learned in to the Control Panel, the Control Panel can remotely control the Relay Channel 1/2/3 to turn On/Off. Please refer to your Control Panel for details.
l The user can also manually press the Switch Button 1/2/3 to switch ON/OFF the Relay Channel 1/2/3.
Supervision
l After the Relay Switch is successfully learned in to the Control Panel, the device will automatically transmit Supervisory signals periodically to the Control Panel at random intervals of 30 to 50 minutes.
l If the Control Panel has not received the signal from the Relay Switch for the preset period of time, the Control Panel will indicate on its display that the particular Relay Switch is experiencing an out-of-signal problem.
Factory Reset
l Factory resetting the Relay Switch will restore it to factory default settings.
l Press and hold the test button while powering on the Relay Switch, then release the button when LEDs light up to factory reset.
