49-537.fm Page 2 Thursday, August 19, 1999 9:16 AM INTRODUCTION Your Radio Shack Digital Key Switch is a highquality, UL-approved security keypad that connects to your alarm system and eliminates the need for a key to arm and disarm your alarm. Instead, you simply enter your personally selected four-digit code. The keypad’s microprocessor lets you select from 10,000 possible codes. You can change the code as often as you like. Your keypad has these features.

Built-in Tamper Switch— sounds the alarm if someone tries to remove or damage the switch. Wrong Number Lockout —makes you wait 10 seconds between incorrect attempts to discourage random code number entries by unauthorized persons. This product is UL listed under Standard Number 1023, “Household Burglar-Alarm System Units.” Use only with UL-Listed security devices.

49-537.fm Page 5 Thursday, August 19, 1999 9:16 AM READ THIS FIRST Properly connecting and installing the keypad requires careful planning before you begin. Read this entire manual and plan your installation before continuing. This manual includes specific connection drawings for Radio Shack alarm systems as well as general information for use with other security devices. Check your security device’s owner’s manual for specific instructions.
49-537.fm Page 6 Thursday, August 19, 1999 9:16 AM • What other hardware and tools do you need? — you should mount the keypad in a standard single-gang electrical box (the kind used for single wall switches and AC outlets). See “Installation.” Once you install this box, all you need is a screwdriver to complete the keypad’s installation. Note: You can mount the keypad directly on wooden or plasterboard walls, without an electrical box. However, the box gives added security and protection.
49-537.fm Page 7 Thursday, August 19, 1999 9:16 AM CONNECTIONS This section gives basic guidelines for connecting the wires from your alarm system to the keypad. If you are using a Radio Shack alarm system, see the separate wiring diagrams for the exact connections. The keypad is compatible with many alarm systems. However, some systems might not use all the keypad’s features. Also, each system requires some variations in wiring connections.
49-537.fm Page 8 Thursday, August 19, 1999 9:16 AM REMOTE N.O. (Normally Open) Terminals —these terminals connect to your alarm system’s remote arm/disarm terminals. They provide the switch closure needed to arm and disarm the alarm. Note: Some systems require connection to normally closed remote arm/disarm terminals. If your system has a normally closed switch, you must set LATCH to IN and enter your code twice to arm and disarm the system. TAMPER/PANIC (N.O.
49-537.fm Page 9 Thursday, August 19, 1999 9:16 AM ARM LED Terminals (+/–)—these terminals connect to the alarm’s remote arm indicator terminals. Follow the marked polarity (+ and –) to make the connection. When power is applied to these terminals, the red ARM indicator on the front panel turns on. Notes: • Some systems might not have connections for remote arm indicators. These connections are not necessary for operation.
49-537.fm Page 10 Thursday, August 19, 1999 9:16 AM LOOP LED Terminals— these terminals connect to your alarm system’s remote loop indicator terminals. Follow the marked polarity (+ and –). When power is applied to these terminals, the green LOOP indicator turns on. Notes: • Some systems might not have connections for remote loop indicators. These connections are not necessary for operation.
49-537.fm Page 11 Thursday, August 19, 1999 9:16 AM HOW AND WHEN TO USE THE JUMPER The keypad has a three-terminal jumper connected to the positive (+) side of the ARM, LOOP, and POWER terminals. If your system uses a common positive power supply for these three connections, you can route a single wire from your alarm panel and connect it to one terminal. The jumper bridges power to the other two terminals.
49-537.fm Page 12 Thursday, August 19, 1999 9:16 AM If your system has common negative (–) connections for its indicators, move the jumper to the negative ARM, LOOP, and POWER terminals and make connections similar to the drawing below. Illustration: Connection negative common. If your system does not have polarity markings or other means of determining the common terminal, route a separate wire from your alarm system to each terminal.
49-537.fm Page 13 Thursday, August 19, 1999 9:16 AM INSTALLATION Installation Hints: • Before installing the keypad, temporarily connect the alarm and the keypad terminals to confirm proper operation. If you have problems, see “Problem Solving.” • Install the switch indoors away from dust, dirt, and temperature or humidity extremes. Refer to the illustration on Page 16 and follow these steps to install the switch. 1. Select a location on the wall next to a wall stud. 2.
49-537.fm Page 14 Thursday, August 19, 1999 9:16 AM 5. Connect the wires to the keypad terminals. If connecting to a Radio Shack system, refer to the supplied wiring diagrams. Otherwise, refer to “Connections.” To make a connection: a. Loosen the keypad’s screw terminal. b. Strip 1/2 inch of insulation from the wire end. c. Wrap the bare wire around the screw terminal. Be sure no stray wire strands touch any other terminal. d. Tighten the screw. 6. Set LATCH IN/OUT to the correct position for your system.
49-537.fm Page 15 Thursday, August 19, 1999 9:16 AM • When set to OUT, the keypad shorts the remote terminals for 21/2 seconds when you enter the code. Use this setting if the original arm/disarm switch is a spring-loaded type, normally-open switch that has a momentary contact. If you are not sure what setting to use with your system, check your system’s owner’s manual or contact the manufacturer. Notes: • Set LATCH IN/OUT before you connect power to the switch.
49-537.fm Page 16 Thursday, August 19, 1999 9:16 AM 8. Secure the keypad to the box using two screws. Then replace the keypad’s front cover and secure it with the screw you removed in Step 7. 9. Connect the other end of the wires to the appropriate terminals on your alarm system. 10. Carefully push the wires into the box and attach the keyboard portion of the keypad to the box using the supplied set screw. Illustration: Installing the Key Switch.
49-537.fm Page 17 Thursday, August 19, 1999 9:16 AM OPERATION AND TESTING SETTING THE SECURITY CODE When you first connect power to the keypad, and any time after the keypad loses power, it uses the preset factory security code (1 2 3 4). Follow these steps to set your own security code. Note: If you take longer than 10 seconds to complete Step 2, 3, or 4, the keypad automatically resets to the old code. Begin again from Step 1. 1. Press Q. 2. Enter the current security code. 3. Press Q again. 4.
49-537.fm Page 18 Thursday, August 19, 1999 9:16 AM • If you make an error when entering your new code, press # to clear the incorrect entry and repeat this step. 5. Press Q to store the new code. Note: If you forget the code number, temporarily disconnect power from the keypad. This resets the code to the factory default code (1 2 3 4).
49-537.fm Page 19 Thursday, August 19, 1999 9:16 AM ARMING/DISARMING THE ALARM To arm the system, enter your code. If you connected the keypad to your system’s remote arm indicator terminals, the ARM indicator should light. Note: If the ARM indicator lights when the system is disarmed, you have probably connected the keypad to the wrong remote arm terminals on the alarm system. Check all connections and try again. To test the system, arm the system, then set off the alarm to confirm its operation.
49-537.fm Page 20 Thursday, August 19, 1999 9:16 AM • If the keypad does not respond to your code, there might have been a power failure while you were away or there might be a loose, intermittent connection at the POWER terminals. In either case, the keypad resets to the factory code (1 2 3 4) when power is restored. ARM AND LOOP INDICATORS The operation of these indicators varies depending on the type of alarm system you use. Some systems use both indicators, while others might use only one or neither.
49-537.fm Page 21 Thursday, August 19, 1999 9:16 AM PANIC CIRCUIT If you connected the keypad’s PANIC terminals to a 24-hour panic/tamper loop on your alarm system, pressing # and Q at the same time trips the alarm, whether or not the system is armed. On some alarm systems, you can silence the panic alarm by entering your code at the keypad. If this does not work, reset it at the main alarm system.
49-537.fm Page 22 Thursday, August 19, 1999 9:16 AM PROBLEM SOLVING If you have problems, these suggestions might help. Keypad does not arm or disarm your system. • Be sure all connections are correct. • Check for the proper setting of LATCH IN/OUT. • The security code resets to the preset factory code (1 2 3 4) if power has been disconnected. You cannot remember your code. • Temporarily disconnect power to reset to the factory code (1 2 3 4).
