ADVANCED SYSTEM SOFTWARE
The Alpha 500 series utilizes advanced microprocessor control with highly evolved system software That has redundant error-checking and correcting capabilities to ensure 100% error-free encoding, transmitting, receiving, decoding, and controlling all of the output relays. This highly evolved system software includes CRC (Cyclical Redundancy Check) and Hamming Codes (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-detention - auto-shutoff. and receiver MAIN relay auto disconnect then system is in sleep mode, radio interference. system run of receiving range and when transmitter low voltage condition is detected
Both transmitter and receiver utilize advanced microprocessor control. The availability of 32.768 sets of unique ID codes + 20 distinct RF channels ensure 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 receiver MAIN relay circuits If the receiver MAIN relay is defective (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.
Power Saving Circuits
The transmitter utilizes advance power-saving circuits providing more than 150 hours of continuous operation between battery replacements using just Iwo (off-the-shelf “AA' alkaline The extremely long battery life eliminates the need for frequent replacing or recharging of batteries
20/30 User-Selectable RF channels
The receiver IS equipped a PLL. (Phase Lock Loop) synthesized
RF module with 20(301MHz) / 30(433MHz) sets of user selectable RF channels (narrow band FM) adjusted via simple dip-switch settings. The transmitter is equipped with a unique removable transmitting RF board for easy replacement of transmitting RF channels.
Lightweight and Compact
The keypad arrangement results in a transmitter that is ultra lightweight and compact in design. Including batteries the transmitter handset is weighted at only 200g for the 4-button models. 240g for the 6-button models. and 290g for the 10-button models. This optimized design is almost 50% smaller and tighter than most competitive models and much easier to carry and operate
Waterproof and Durable
The transmitter and receiver enclosure are constructed from high grade composite materials that resist cracking and deformation commonly occurred from frequent drops and long term exposure to heat, sunlight and harsh environments. The enclosures are fully sealed and impervious to dust, water, oil, acids, alkaline, heat and sunlight, which provide trouble-free operation in high moisture environments and outdoor applications
Industry's Best 2-speed Push button
Custom in-house designed 2-speed pushbuttons are extremely durable and reliable for a minimum of one million press cycles Unlike most s-speed pushbuttons available from other radio control manufacturers these pushbuttons are easily manipulated even when the operator is wearing gloves. The snap action steps provides positive tactile feedback to the operator.
The Alpha 500 series are designed and manufactured in accordance with FCC Part 15 Rules, European directives (CE/CB). Industry Canada Specifications (IC) and ISO[
9001 guidelines. No site license is required
