N9KSMARTECRF1252R900MHz Transceiver of Intercom Unit

Thank you for purchasing the GTO Wireless Gate Entry Intercom/Keypad. Be sure to read the directions carefully and completely. Before permanently mounting the keypad, please program the keypad and test its range. IMPORTANT: Your intercom/keypad may need to be hard wired due to the fact that it must accept interference accord- ing to FCC regulations listed below. For example, applica- tions that are relativity close to cell towers or airports may receive intermittent interference and require hard-wiring. As a wireless intercom/keypad it can be used with any gate opener that receives a 318 MHz RF signal. SAFETY NOTE: Never install the keypad portion of this unit where a person can reach through the gate to activate it, or where a person can touch the gate while activating the key- pad. The recommended minimum distance between the gate and keypad is 10 ft. Wireless Gate Entry Intercom/Keypad Instructions for Wired and Wireless Installations Features of the Intercom/Keypad The intercom/keypad has two separate units. The outside unit should be mounted outside the gate allowing the driver of the vehicle approaching the property to press the CALL button from their vehicle and the inside unit with it’s rechargable battery can be plugged into any 110 Volt AC outlet for use while charging or it can be disconnected form the electrical cord allowing it to go anywhere within range for convenience. When someone without an access code approaches the gate they will press the CALL button on the outside keypad unit which will ring the inside unit. To answer the CALL, the person inside presses and holds the ANSWER button to talk to the person at the gate, releasing the ANSWER button it to listen. To allow the person calling to open the gate the GRANT PERMISSION button must be pressed then the person at the keypad can press any key to open the gate. Up to 25 different personal entry codes may be programmed into the outside keypad, allowing you to give different entry codes to dif- ferent users. For example, you can give a delivery person their own entry code, which you can easily change after they have made the delivery. This will prevent them from being able to regain access, while still allowing those to whom you gave other entry codes full access. After entering a valid code, pressing any key while the gate is opening will stop the gate; pressing any key while the gate is stopped and the gate will reverse direction. The keypad will not affect the auto-close setting of your gate opener system. The keypad face will light up and beeper will beep at the press of any key. The keypad memory will recognize your entry code in a string of up to 20 digits; if it fi nds the correct sequence it will activate the gate opener. As a security feature, the keypad will shut down for 40 seconds if it does not fi nd the correct code sequence within a 20 digit string. This will discourage an unauthorized person from trying to use random numbers to access your property. Your entry codes will remain stored in memory even when the batteries go dead. The keypad will remember your entry codes as long as you don’t press the RESET button. ©2005 GTO, Inc.rev - 02-28-05 FCC WARNING: Changes or modifi cations to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in particular installations. If this equipment does cause harmful interference to radio or television recep- tion, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or replace the receiver antenna. • Increase the separation between the equipment and the receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. Wired Installation of the Keypad NOTE: If you also plan to power the keypad with the gate opener’s power source, run two pairs of wires as described below. One pair to hard-wire the keypad and the other pair to connect the keypad to the gate opener’s battery. Step 1: Turn the gate opener’s power switch OFF. Use 16 gauge, stranded, direct burial low voltage wire (part no. RB509) to connect the keypad to the opener control board. Run wire through PVC pipe from the ground to keypad and from the ground to the opener control board to protect the wire from lawn mowers or grazing animals. Determine how the wire will enter the keypad (i.e. from the back through a hole drilled in the mounting post or running the wire on the surface of the post). Remove the small rectangular knock-out on the back of the keypad cover and pull the wire into the cover. Then mount the cover to the post using the screws provided. Keypad Description Installing Batteries NOTE: 3 AA batteries are required to power the keypad unless an external power supply such as the gate openers power source is used. Low voltage wire from the external power source must be connected to the POWER IN terminals on the keypad control board, if batteries are not installed. Step 1: Remove the two screws from the bottom of the keypad and sepa- rate the keypad from its housing. Step 2: Install 4 AA batteries (not included). �� ��� � ��� � ��� � ��� � ��� � ��� � ��� � ��� � ���� ������ ������� ������� ������� STATUS Light: This led will blink once when any key is pressed and provides visual feedb…

Utilizing a unique direct-conversion, zero-intermediate frequency (zero-IF) receiver architecture, WE904/905 provides radio designers a high performance RF transceiver solution with low external component count and small PCB footprint. The receiver section of the WE904/905 provide all of the required receiver functions including local oscillator synthesis (VCO), down-conversion, filtering, automatic gain control (AGC), automatic frequency control (AFC), FM/FSK demodulator and RSSI functions. The transmitter section contains a directly modulated VCO and RF power amplifier (PA). Internal, dual, high-performance phase locked loop (PLL) synthesizers/VCOs allow full duplex or half- duplex operation over the entire RF tuning range. Tuning, power management, and gain control (manual) functions are accomplished via serial interface.
