Allmatic ASR2 433/AP LED AM: 2-Channel Fixed Code Receiver

Description

The ASR2 433/AP LED AM is a 2-channel receiver for fixed code radio commands, managing two clean contact relays with independent learning capabilities for each relay.

How to Memorize a Transmitter Code

1. Connect power to the receiver at terminals 5 and 6, ensuring the correct power supply voltage jumper (Jumper C) is set.
2. Press the learning button briefly to initiate the radio command learning phase. LED1 indicates the learning phase is active, while LED2/3 indicate the channel being learned.
3. Pressing the button once activates learning for channel 1 (LED2 on). Pressing it again activates learning for channel 2 (LED3 on).
4. Select the desired channel and transmit the radio command to be memorized. The receiver will signal successful memorization with the channel's LED and then reactivate the learning mode.
5. The learning mode exits automatically after 10 seconds of inactivity or upon subsequent presses of the button on the card, indicated by all LEDs turning off.

Attention: If LED 2/3 does not blink during memorization, the code was not stored. Verify the transmitter's frequency matches the receiver's and it uses a fixed code. If the memory is full, the maximum number of transmitters has been learned.

How to Cancel All Transmitters and Settings (Reset)

1. Disconnect power from the receiver card.
2. Press and hold the learning button while reconnecting power. LED 1 will illuminate after approximately 5 seconds.
3. Release the receiver button.
4. Wait for LED 1 to blink (2 or 3 times). All codes are erased when the LED turns off.

Function Selection

The relays can operate in three modes:

• IMMEDIATE: The relay remains active as long as the radio signal is present (button pressed).
• STEP-BY-STEP: The relay activates and remains active until the next command is received (button pressed again).
• ON TIME: The relay activates and remains active for a programmable duration, from 1 second to 18 hours.

Set the jumpers as indicated to select the desired operating mode.

Setting of Functions

Each channel and relay is associated with a jumper:

• JUMPER A: Channel/Relay 1
• JUMPER B: Channel/Relay 2

Mode Selection:

• MODE 1: Jumper closed - STEP-BY-STEP operation.
• MODE 2: Jumper open - IMMEDIATE / TIMED operation.

Timed Function Modality

With the immediate/timed modality activated (jumper removed), the type of timing (immediate or prolonged) can be modified via the configuration menu:

1. Activate the menu by pressing and holding the button on the card until LED2 blinks concurrently with LED1 turning on. The channel LED's blinking indicates the current selection: fast blinking for immediate, slow blinking for timed.
2. To move to the next channel, press and hold the button on the card for at least 3 seconds.
3. Once the channel is selected, modify the timing type by pressing and releasing the button on the card to achieve the desired timed modality, indicated by a slow blink of the corresponding relay's LED.
4. To program the duration, transmit a radio command associated with the active channel. The channel LED will blink every 1 second to indicate the time passing.
5. Once the desired time has elapsed, finish programming by transmitting another radio command. The maximum programmable time is 18 hours.

The programmed time is stored until the next programming or receiver reset. If both relays are configured for timed operation, the activation time can be set identically for both by pressing the button for 3 seconds, causing LED 2 and 3 to illuminate. The menu exits via timeout after 10 seconds of inactivity or by pressing the button for 3 seconds, which turns off all LEDs.

Warning: If the receiver unit is powered by AC voltage, use an isolation transformer (SELV compliant) with limited power or short-circuit protection.

Installation

• Connect according to the diagram, setting Jumper C for the appropriate voltage (12 Vac/dc with jumper closed, 24 Vac/dc with jumper open). This feature is available on the terminal board version.
• Supply power to terminals 5 and 6 (AC or DC).
• If using multiple receivers, space them 3-4 meters apart to prevent interference.
• Connect a good quality ground to terminal 7 (screw terminal version) or terminal 9 (plug-in connector version).
• Position the antenna away from or above metal structures and obstacles. Connect the antenna signal to terminal 8 (screw terminal) or 10 (plug-in), and the shield to terminal 7 (screw terminal) or 9 (plug-in).
• The antenna is crucial for maximum range; without it, the range is significantly reduced.
• If the antenna cable is too short, replace it with a suitable length of 50-ohm impedance cable (e.g., RG58), not exceeding 10 meters. Do not splice cables.
• When wall-mounting, use appropriate screws and anchors to withstand a 50N downward force.

Warnings and Suggestions

• Before powering the receiver card, select the correct supply voltage using Jumper C.
• If the unit is not functioning, check:
• Receiver power supply.
• Transmitter battery condition.
• Correct antenna installation.
• If LED 1 is continuously blinking approximately once per second, the memory module may be disconnected or damaged.
