Alpha 3000 Series

Quesco is a leading name in the sales industry, particularly renowned for their Alpha 3000 series which features industry's best 2 & 3-speed pushbuttons. The Alpha 3000 series operates on advanced "risc" microprocessors and advanced system software, making it a preferred choice for many. Quesco’s Alpha 3000 series is encased in a metal receiver which is 100% water-resistant, exemplifying their commitment to creating durable, rugged, reliable and safe products. The Alpha 3000 series is also appreciated for its ultra power-saving capabilities. Trust Quesco for the best in the sales industry - where innovation meets safety and durability.

Advanced System Software

The Alpha 3000 series utilizes advanced RISC microprocessor control with highly evolved system software that has redundant error checking and correcting capabilities to ensure 1001 error-free encoding, transmitting, receiving, decoding, and control of all output relays. This highly evolved system software includes CRC (Cyclical Redundancy Check) and Hamming Code (Error Recovery).


Safe and Reliable Operation

To ensure maximum operating safety the system incorporates numerous important safety features, which include transmitter pushbutton fault-detection - visual warning - auto-shutoff, transmitter low­ voltage detection • visual warning - auto-shutoff, receiver fault-detection - auto-shutoff, and receiver MAIN relay auto-disconnect when the system is in sleep mode, radio interference, system out of receiving range, and when transmitter low-voltage condition is detected.


Secure Operation

Both transmitter and receiver utilize advanced 16+1 bit microprocessor control. The availability of 65,536 sets of unique ID code + 20 distinct RF channels ensures that only commands from a matching control transmitter can be carried out, reducing the risk of interference from outside sources.


Safety MAIN Relay Circuits

For added safety, the receiver system utilizes a special 'Safety Relay' for the MAIN relay circuits, If the receiver MAIN relay is defective (for example: fails to open or close during operation or not responding to a Stop' command) a fault will be detected and the system will be shut down immediately to avoid possibility of any accidents occurring.


Ultra Power Saving Circuits

The transmitter utilizes advanced power-saving circuits providing more than 250 hours of continuous operation between battery replacements using just four (4) off-the-shelf 'AA alkaline batteries, The extremely long battery life eliminates the need for frequent replacing and recharging of batteries.


Industry's Best 2 & 3-speed Pushbuttons

Custom in-house designed 2 and 3-speed pushbuttons are extremely durable and reliable for a minimum of one million press cycles. Unlike most 2 and 3-speed pushbuttons available from other radio control manufacturers, these pushbuttons are easily manipulated even when the operator is wearing gloves. The snap­-action steps provide positive tactile feedback to the operator.


20 User-Selectable RF Channels

The receiver is equipped with PLL (Phase Lock Loop) synthesized RF module with 20 sets of user­-selectable RF channels (narrow band FM) adjusted via simple dip-switch settings.


Durable and Rugged Transmitter

The transmitter enclosures are constructed from industrial-strength composite materials (Nylon + Fiberglass) that resist cracking and deformation commonly occurring from frequent drops and long-term exposure to heat, sunlight, and harsh environments


100% Sealed Enclosure

Both transmitter and receiver enclosures are fully sealed and impervious to dust, water, oil, grease, acids, alkaline, heat and sunlight, which provide trouble-free operation in high moisture environments and outdoor applications. The receiver enclosures are fully painted inside and out with stainless steel hinges and key lock.


Modular Receiver

The modular design of the receiver provides easy service maintenance of all internal components. The RF module, decoding module, upper/lower relay boards and power transformer are all placed independently inside ( the metal enclosure,


Full Compliance

The Alpha 3000 series are designed and manufactured in accordance with FCC Part-15 Rules, European Directives (CE/CB), Industry ,Canada specifications (IC) and ISO 9001 guidelines.
