AES E-TRIGGER-K, Wireless Relay Transmitter includes eTrans50 Transceiver
The AES E-TRIGGER-K is a wireless relay transmitter kit that includes the AES E-TRIGGER transmitter and an ETRANS50 transceiver. It is designed for compatible AES wireless access control applications where a trigger signal needs to be sent from one location to another without running a direct control wire between the access device and the gate motor or door controller.
This kit is commonly used with intercoms, keypads, card readers, access control panels, and third-party trigger devices that need to activate a relay at a gate operator, automatic door, or controlled entry point. The E-TRIGGER acts as the wireless transmitting side, while the included ETRANS50 transceiver is installed at the receiving side near the controlled equipment.
The E-TRIGGER-K should be ordered by exact AES part number, kit contents, operating frequency, input method, and relay requirement. Do not choose this kit only because a site needs wireless control. Frequency, transceiver compatibility, relay mode, wiring method, voltage, range, antenna placement, and safety requirements all need to be checked before installation.
What This Wireless Relay Kit Does
The AES E-TRIGGER-K creates a wireless relay bridge between a trigger device and the equipment being controlled. When the intercom, keypad, access controller, or third-party device activates the E-TRIGGER input, the signal is sent wirelessly to the paired ETRANS50 transceiver.
The ETRANS50 then provides the relay output used to activate the approved input on the gate operator, door controller, or access control equipment. This can save installation time where trenching, conduit, or long trigger wire runs are difficult, expensive, or not practical.
This kit does not make the controlled device safe or properly configured by itself. Gate or door operation still depends on correct relay wiring, operator programming, access control settings, monitored safety devices, entrapment protection, and proper field testing.
Compatible With
Use the AES E-TRIGGER-K only where the AES documentation, site design, receiver/transceiver requirements, or supplier cross-reference confirms compatibility. Compatibility depends on the E-TRIGGER input, ETRANS50 transceiver setup, relay output requirements, power source, and site radio conditions.
- Select AES wireless relay bridge applications where E-TRIGGER-K or E-TRIGGER-KIT is listed as the required kit
- Installations requiring one E-TRIGGER wireless transmitter and one ETRANS50 transceiver
- Gate operator trigger applications where the ETRANS50 relay output is wired to an approved open, push-button, radio, free-exit, or access control input
- Automatic door or access control applications where the receiving relay output is approved for the controlled equipment
- Intercom, keypad, card reader, telephone entry, or third-party trigger devices that provide a compatible trigger input to the E-TRIGGER
- Applications using AES 433.39 MHz wireless communication where range and site conditions allow reliable operation
- Repairs or upgrades where the original kit is marked, listed, or cross-referenced as E-TRIGGER-K, E-TRIGGER-KIT, or AES E-TRIGGER kit with ETRANS50
Important Compatibility Warning
The AES E-TRIGGER-K is the kit version and should not be confused with the E-TRIGGER transmitter-only item. If the site already has a compatible ETRANS50 or other supported AES transceiver, the transmitter-only version may be the correct item instead. If the site does not have a compatible receiving transceiver, the transmitter-only version will not complete the wireless bridge.
Do not assume this kit works with every gate operator, door controller, intercom, or generic 433 MHz receiver. The ETRANS50 relay output must be wired to an approved low-voltage control input, and the E-TRIGGER input must match the trigger device being used.
Wireless range is site-dependent. Metal gate posts, electrical enclosures, masonry walls, long driveways, underground wiring areas, antenna placement, nearby electronics, and radio interference can reduce performance. Test the kit from the intended mounting locations before finalizing the installation.

Technician Note
If the AES E-TRIGGER-K does not activate the gate or door, troubleshoot both sides of the wireless bridge. Check the trigger device output, E-TRIGGER input wiring, E-TRIGGER power or battery, ETRANS50 power, pairing, relay mode, antenna placement, range, interference, and the gate operator input.
If the ETRANS50 relay clicks but the gate does not move, the problem is usually not the wireless transmitter. Check the operator input wiring, input programming, access control wiring, fire access interface, lock controller, safety circuit, and operator status before replacing the kit.
If the wireless link is intermittent, inspect mounting location and radio path before assuming the electronics are defective. Metal posts, steel cabinets, long cable runs, buried devices, and nearby electrical noise can create range issues even when the kit is functioning normally.

Installation and Service Notes
- Install and program the E-TRIGGER-K only on systems you are authorized to service.
- Follow AES instructions for pairing the E-TRIGGER to the included ETRANS50 transceiver.
- Confirm wiring polarity, input type, relay output, and power requirements before energizing the system.
- Do not connect the relay output to high-voltage circuits or unsupported operator inputs.
- Set the ETRANS50 relay mode only as required by the controlled equipment, such as Pulse, Latch, or Hold where supported.
- Mount the transmitter and transceiver where the radio path is as clear as practical and protected from water intrusion.
- Test the wireless link from the final mounting locations before completing the installation.
- After setup, test the trigger device, wireless transmission, ETRANS50 relay output, and controlled gate or door response.
- Do not bypass monitored gate safety inputs, photo eyes, safety edges, emergency access equipment, fire access wiring, access permissions, or required entrapment protection during testing.
Professional Advisory
A qualified gate, access control, or low-voltage technician should install or service the AES E-TRIGGER-K when it is connected to a gate operator, automatic door, magnetic lock, electric strike, intercom, telephone entry system, fire access system, or monitored safety circuit. A wireless relay bridge should not be used to bypass required safety devices, access permissions, fire access requirements, or gate operator protections.
Product Questions & Answers
What is included with the AES E-TRIGGER-K?
The AES E-TRIGGER-K is the wireless relay transmitter kit version and is commonly listed with one E-TRIGGER wireless transmitter and one ETRANS50 transceiver. Confirm the package contents before ordering.
What is the AES E-TRIGGER-K used for?
The AES E-TRIGGER-K is used to create a wireless relay bridge between an intercom, keypad, access control device, or third-party trigger and a compatible gate motor, door controller, or relay input.
Is AES E-TRIGGER-K the same as AES E-TRIGGER?
No. E-TRIGGER usually refers to the wireless relay transmitter only. E-TRIGGER-K or E-TRIGGER-KIT refers to the kit version that includes the ETRANS50 transceiver where supplied as listed.
Does the E-TRIGGER-K include the ETRANS50 transceiver?
Yes. Current kit listings identify the E-TRIGGER-K / E-TRIGGER-KIT as including an ETRANS50 transceiver along with the E-TRIGGER wireless transmitter. Always verify the physical package before ordering.
Can AES E-TRIGGER-K replace a direct trigger wire to a gate motor?
In compatible installations, yes. The kit can send a trigger signal wirelessly to the ETRANS50 transceiver at the gate motor or controlled device, but the relay output still must be wired to an approved operator input.
What power does the ETRANS50 transceiver require?
The ETRANS50 is commonly specified with 10-36V DC input, low standby current, 433.39 MHz operation, and a 1A relay contact. Confirm the current manual and installation requirements before wiring.
What should I check before ordering AES E-TRIGGER-K?
Confirm the exact E-TRIGGER-K or E-TRIGGER-KIT part number, included ETRANS50 transceiver, compatible trigger device, relay requirements, power source, wireless range, mounting location, package contents, and whether the job needs the kit or transmitter-only version.
