DIGITAL KEY SWITCH
f=iS A F E .
HOUSE
Your SAFE HOUSE Digital Key Switch is a high quality, U.L. approved security device designed and manufactured in Tandy Corporation's own factories. It eliminates the need to carry a key for arming/disarming your alarm system. instead, you simply enter your personally selected 4-digit code. The unit's microprocessor allows you to select from 10,000 possible codes. Note: You may change the code as often as you like. Other features available with the Digital Key Switch are:

Digital Key Switch requires a standard single-gang electrical box for mounting (the same kind used for single wall switches and AC outlets). Once this box is installed, only a screwdriver is needed to complete the installation. Note: This unit may be mounted without the electrical box in wood walls (using wood screws) or on plasterboard walls (using molly bolts). However, the box will give added security and protection. After reading this manual, you should be able to answer the above questions and begin installation.

CONNECTIONS
The Digital Key Switch is compatible with many alarm systems. However, some alarm systems might not use all of the Digital Key Switch's connections and features, and each system will require some variations in wiring connections. Pages 4-9 give basic guidelines for connection. If you are using a Radio Shack alarm system, see the separate wiring diagrams for exact connect ion. REMOTE Normally Open/Normally Closed Terminals connect the appropriate pair of these terminals (N.O. or N.C.) to the remote arm/disarm terminals on your alarm; consult the manual for your system. The center terminal is a common connection for both N.O. and N.C. arm/disarm switches. Note: Systems may vary as to whether the armed or disarmed state of their arm/disarm switch is considered to be the "normal" state. If you are not sure about your system, see "OPERATION AND TESTING." LATCH IN/OUT Switch - set this switch for the type of switch closure necessary to operate your system's arm/disarm switch (latching = IN, momentary= OUT). If you are not sure what type of closure is needed, check your system's owner's manual or contact the manufacturer. Note: This switch must be set before power is connected to the Digital Key Switch. After power is applied, the microprocessor will not recognize a change in the switch setting. nals

ARM LED Terminals (+/-) -connect to the remote arm indicator terminals on your alarm system. Be sure to observe the marked polarity (+ and -). Note: Some systems might not have connections for remote arm indicators. If your system has the schematic symbol for a diode above its terminals instead of polarity markings, use the following drawing to determine the correct connections.
LOOP LED Terminals - connect to the remote loop indicator terminals on your alarm system. Be sure to use the marked polarity (+ and -). Note: Some systems might not have connections for remote loop indicators. If your system has the schematic symbol for a diode, instead of polarity markings, use the drawing on previous page to determine the correct connections. POWER Terminals (DC 1 0-20V)-connect to a constant source of 10-20 volt DC power provided by your alarm system. Be sure to observe the marked polarity (+ and -). Jumper (on + terminals) - allows for one connection to the "common" side of the alarm circuit. If your system uses a negative (-) common, move the jumper to the negative ARM, LOOP, and POWER terminals. If you cannot determine which terminal is "common" on your system, remove the jumper and make separate connections for each terminal.

HOW AND WHEN TO USE THE JUMPER
The Digital Key Switch is supplied with a three-terminal jumper connected to the positive (+) side of the ARM, LOOP, and POWER terminals. This eliminates multiple connections to the "common" indicator terminals. If your system has common positive (+) connections for its indicators, leave the jumper as it is and make connections similar to the drawing below. Alarm System with Positive (+) Common Circuits

INSTALLATION
Installation Hints
I 1
Before installing the Digital Key Switch, make temporary connections between the alarm system and the Digital Key Switch to confirm proper operation. If you have problems, see "OPERATION AND TESTING." Install the Digital Key Switch indoors where it will not be subjected to dust, dirt, or extremes in temperature or humidity. Set the LATCH IN/OUT switch before power is connected to the Digital Key Switch. 1. Select a location on the wall that is next to a wall stud. 2. Using a single-gang electrical box as a template, make a hole just large enough to accept the electrical box. 3. Run the necessary wires from the alarm system to the hole (through attic, walls etc.) and through one of the knock-out plugs in the electrical box. Be sure to leave enough extra wire to allow for connection to the Digital Key Switch. 4. Insert the box into the hole and nail it to the wall stud; the box should be recessed slightly below the surface of the wall.
5. Connect the wires to the Digital Key Switch terminals, as described in the manual. Be sure to avoid stray wires that touch other terminals or the sides of the box. 6. Carefully push the wires into the box and attach the keyboard portion of the Digital Key Switch to the box using the two supplied screws. 7. Hang the Digital Key Switch cover plate at the top of the Digital Key Switch and secure it at the bottom using the supplied set screw. Note: The cover plate holds in the tamper switch plunger. If the tamper switch is connected to a 24-hour panic/tamper loop on your alarm, the alarm will be tripped if the cover plate is removed, even if the alarm is not armed.

OPERATION AND TESTING
IMPORTANT
To prevent false alarms when testing your system, be sure to disconnect security dialers or any other devices that sends a message to a remote location. It is also a good idea to temporarily replace bells or other sounding devices with a 1 Z-volt bulb that draws less than 1 amp. SETTING YOUR SECURITY CODE When power is first connected to the Digital Key Switch, the preset factory security code will be in effect. This code is [ 1 2 3 4]. 1. Press [*]. 2. Enter the current security code -the preset factory c o d e ([1 2 3 4]) or any code you have previously selected. 3. Enter your personal code - the code may be any four digits; you may repeat a digit as many times as 9 S 3 you like. For example: [3 5 6 4], [5 5 5 9],, or [9 8 2 2]. Note: We suggest you avoid obvious numbers such as your street address, birth date, etc. Also, it is a good idea to periodically change your code. 4. Press [ *] a final time to complete the code entry.

Notes
l If you take more than 10 seconds to complete step
2, 3, or 4, the Digital Key Switch will automatically reset to the old code. You must begin again with step 1.
0
If you make an error before completing step 4, press [ # ] (clear) and begin again with step 1. If you realize you made a mistake in the new number after completing all steps, you must repeat the process using the incorrect code number in step 3. If you do not know, or remember, the code number, temporarily disconnect power from the Digital Key Switch. This will reset the code to the factory code number ([ 1 2 3 4]). Then begin with step 1.

ARMING/DISARMING THE ALARM SYSTEM
After your code is selected, enter the number to arm the system; the ARM LED indicator should light (if such connections were made during installation).
1.
ARM AND LOOP INDICATORS The operation of these indicators will vary depending on the type of alarm system you use. Some systems will use both indicators; others might use only one or neither. I n most cases, these indicators should respond in the same way OS corresponding indicators on the main alarm unit. If connections are made and the indicators do not work, check for loose connections, incorrect polarity, etc. PANIC CIRCUIT If the PANIC terminals on the Digital Key Switch are connected to a 24-hour panic/tamper loop on your alarm system, simultaneous pressing of. [ # ] . and [ * ] should trip the alarm at any time, whether or not the system is armed. On some alarm systems (49-450, for example) you may reset the alarm by entering your code at the Digital Key Switch. If this does not work, you will have to reset it at the main alarm unit.
Note: If the action of the ARM LED is reversed (the indicator lights when the system is disarmed), you have probably used the wrong REMOTE Normally Open/ Normally Closed terminals. Change the connections and try it again. 2. Trip the alarm and confirm that it is, in fact, armed. 3. Enter your code again to disarm the system. If the Digital Key Switch does not respond to your code, it is possible that there was a power failure while you were away or that there is a loose, "intermittent" connection at the POWER terminals. In either case, the Digital Key Switch will reset to the factory code ([1 2 3 4]) when power is restored.
