Two-Zone Remote Keypad Burglar Alarm Control Center (490-0451) Connections Faxback Doc. # 33422 CONNECTING SENSORS INTO LOOPS After you install all sensors in the locations you noted in your floor plan you can connect your alarm system's sensors together into the three types of loops. Instant Loop (Zone) - Causes the alarm center to sound the alarm instantly when a sensor within the loop is violated, if the alarm system is armed. You can have separate groupings of normally-open and normally closed sensors within this type of loop. Delayed Loop (Zone) - Causes the alarm center to sound the alarm after a preset period of time when a sensor within the loop is violated, if the alarm system is armed. You can have separate groupings of normally-open and normally-closed sensors within this type of loop. Panic/Tamper Loop (Zone) - Causes the alarm center to sound the alarm instantly when a sensor within the loop is violated, even if the alarm system is not armed. You can have a group of only normally-open sensors within this type of loop. Note: When you connect sensors to the loops, make sure all of the sensors within each group are either normally-open or normally-closed. You cannot mix different types of sensors within the same group. To make a loop of normally-closed sensors, you must connect them in series. This means you cut one of the conductors and connect the sensor inline with that conductor. To make a loop of normally-open sensors, you must connect them in parallel. This means you connect both conductors to each sensor along the loop. GROUNDING THE ALARM CENTER You must ground the alarm center using a good earth ground such as an 8-foot ground rod (Cat. No. 15-529, not supplied). Secure one end of a 14-gauge or larger ground wire (not supplied) to the hex-head bolt in the alarm center's lower right corner. Then connect the wire's other end to the ground rod. Follow all local wiring codes. NOTES: Improper grounding can cause false alarms. Use only the recommended grounding method to ground the alarm center. Do not ground it to an object such as a water pipe or electrical conduit. Do not connect grounded metal conduit to the alarm center. If you want to use conduit to protect your system's wiring, use plastic conduit. SYSTEM WIRING CONNECTIONS Use this chart and the following sections to connect the system's wiring to the alarm center.

For more information, see "Connecting and Powering a Remote Security Device" below. Connecting Loops of Sensors to the Alarm Center After you have connected all sensors noted in your floor plan in loops, route the ends of each loop of sensors to the alarm center's location. NOTE: To make it easier to connect the loops of sensors to the alarm center, use tape you can write on to mark the end of each loop's wire pair with its zone type and if the connected sensors are normally-open or normally-closed. After you route the wires for each loop to the alarm center, follow these steps to connect the wires to the alarm center. 1. Use a flathead screwdriver to pry open one of the knockout plugs on the alarm center's case. 2. Route each loop's wires through the plug's hole. 3. Use a screwdriver to remove the jumpers between Terminals 2 and 3 and Terminals 3 and 4. NOTE: Save these jumpers, you might have to re-install them after you connect the loops. 4. Strip about 1/4 inch of insulation from the end of each wire. 5. Use a screwdriver to connect each loop's wires to the alarm center as follows: NOTE: Do not connect more than two wires to a single terminal. If there are more than two wires to connect to a terminal, first connect the wires to an external barrier strip (Cat. No. 274-658, 274-659, or 274-670). Then connect a single wire from the barrier strip to the terminal. Instant Zone (Terminals 1,2, and 3) If you connected normally-open sensors to this loop, connect the loop's wires to Terminals 1 and 3. If you connected normally-closed sensors to this loop, connect the loop's wires to Terminals 2 and 3. Delayed Zone (Terminals 3,4, and 5) If you connected normally-open sensors to this loop, connect the loop's wires to Terminals 3 and 5. If you connected normally-closed sensors to this loop, connect the loop's wires to Terminals 3 and 4. NOTE: Terminal 3 provides grounding for instant and Delayed Zone's loops. One wire of both normally-open and normally-closed loops of sensors is connected to Terminal 3. Panic/Tamper Zone (Terminals 6 and 7) Connect the panic/tamper loop's wires to Terminals 6 and 7. Jumpers on Normally-Closed Terminals Your alarm center is provided with two metal jumpers for your alarm system's normally-closed loops. Both of your alarm center's normally-closed loops must have a complete circuit (either one of the supplied metal jumpers or a loop of normally closed sensors) before the system will arm. Depending on your installation, follow these instructions to install the jumpers. If you did not install any normally-closed loops of sensors, install one jumper between Terminals 2 and 3, then install the other jumper between Terminals 3 and 4. If you installed a normally-closed loop of sensors only in the Delayed Zone, install a jumper only between Terminals 2 and 3. If you installed a normally-closed loop of sensors only in the Instant Zone, install a jumper only between Terminals 3 and 4. If you installed normally-closed loops of sensors both in the instant and Delayed Zones, do not connect any jumpers. CONNECTING A PRE-ALARM BUZZER If you connect a pre-alarm buzzer (such as Cat. No. 273-068, 273-060, or 273-066) to the alarm center, it sounds when the system is armed and a delayed zone is violated. CAUTION: You must use a pre-alarm buzzer that uses 12 volts and is rated at 50 mA or less. The recommended pre-alarm buzzers meet these specifications. Using a pre-alarm buzzer that does not meet these specifications could damage the alarm center or the pre-alarm buzzer. Connect the pre-alarm buzzer's negative (-) wire to Terminal 13, then connect the pre-alarm buzzer's positive (+) wire to Terminal 14. CONNECTING AND POWERING A REMOTE SECURITY DEVICE You can power a remote security device by connecting it to Terminals 14 and 15 on the alarm center. CAUTION: You must use a remote security device that uses 12 volts and is rated at 750 mA or less. Using a device that does not meet these specifications could damage the alarm center or the device. NOTE: The voltage supplied from Terminals 14 and 15 varies from 10 to 18V DC, depending on the AC voltage, battery voltage, and the amount of accessory power being used. Connect the device's negative (-) wire to Terminal 15, then connect the device's positive (+) wire to Terminal 14. CONNECTING A REMOTE SECURITY DEVICE TO THE ALARM RELAY CONTACT SWITCH You can connect a remote security device, such as a telephone dialer, that will be activated when the alarm center is triggered. NOTES: Terminals 11 and 12 do not provide power to the device. They simply turn it on or off. The device you use must have contact switch connections that cause the device to trigger when the alarm center contact switch closes. Connect the device's switch connections to Terminal 11 and Terminal 12. CONNECTING REMOTE KEYPADS You must connect at least the supplied remote keypad to the alarm system to arm and disarm it. You can connect up to three additional Cat. No. 490-0452/or Cat. No. 49-484 remote keypads, in any combination. See "Using a 49-484 Keypad with the Alarm Center" on Faxback Doc. # 33427 for more information about the 49-484 keypads. IMPORTANT: You must connect each remote keypad to the alarm center before you connect power to the alarm system. The alarm center recognizes all connected keypads when it is first turned on, then responds only to those keypads. When the alarm system is on, the alarm center constantly confirms that each keypad is still connected to the system, and vice versa. Setting the Keypad's Address NOTE: If you connect only the supplied remote keypad to the alarm center, you do not need to set the keypad's address. If you connect remote keypad(s) other than the supplied one, you must set the switches on the back of each keypad to assign it a unique address. Set the switches for each remote keypad as follows: Cat. No. 490-0452 Keypad Keypad ADDR1 ADDR2 Number 1 Off Off 2 On Off 3 Off On 4 On On Cat. No. 490-0484 Keypad ADDR1 ADDR2 Number 1 Off Off 2 On Off 3 Off On 4 On On NOTES: 3 (the 3rd switch) on the back of the Cat. No. 490-0484 remote keypad has no function with your alarm center. 4 (The 4th switch) on the back of the Cat. No. 490-0484 remote keypad lets you turn on or off the pre-alarm that sounds during an enter delay. Mounting the Keypad Follow these steps to mount the supplied remote keypad on a wall. NOTE: You need 4-connector phone wire (Cat.No. 278-0386) to connect remote keypads to the alarm system. 1. Select a location on the wall next to a wall stud that is not directly over the stud. NOTE: Radio Shack stores sell an electronic wall stud finder (Cat. No. 640-2825). 2. Using a single-gang electrical box as a template, cut a hole in the wall the size of the box. 3. Route the connection wires for the remote keypad from the alarm center through the hole. Be sure to label each wire to be connected to the remote keypad, and leave enough slack in the wires so you can attach them to the keypad later. 4. Insert the electrical box into the hole. Then secure it to the wall by nailing it to a nearby wall stud, or using metal strips designed for mounting an electrical box in wall board. Make sure the electrical box is recessed slightly below the surface of the wall. 5. Use a Phillips screwdriver to remove the screw from the bottom of the keypad. Then remove the keypad's front cover. 6. Connect the wires to the keypad. For both types of remote keypads, connect POWER (+) on the keypad to Terminal 9 on the alarm center, POWER (-) on the keypad to Terminal 7, SERIAL DATA 1 on the keypad to Terminal 10, and SERIAL DATA 2 on the keypad to Terminal 8. 7. Use the two supplied keypad mounting screws to secure the keypad inside the electrical box.. Then replace the keypad's front cover and replace the screw you removed in Step 5. NOTES: If a Cat. No 490-0452 keypad is disconnected from the alarm center while the system is armed, ARM flashes and the alarm sounds. If a Cat. No. 490-0484 keypad is disconnected from the alarm center while the system is armed, all LEDs flash, the buzzer on the keypad sounds, and the alarm sounds. Press CANCEL on the keypad to silence the buzzer. If either type of keypad is disconnected from the alarm center, you must disconnect the AC adapter and the batteries from the alarm center, then reconnect the power. Then you can use the keypad with the alarm center again. CONNECTING AN ALARM SIREN AND/OR LIGHT You can connect an alarm siren (such as Cat. No. 490-0488 [recommended], 490-0487, or 490-0525) and security strobe or other light (such as Cat. No. 490-0527) to Terminals 15 and 16 on the alarm center. When the alarm system sounds the alarm, it activates the alarm siren and light. NOTE: When you test the system, we recommend you connect a test lamp (Cat. No. 272-1141) to the alarm center instead of the alarm siren and/or light. This lamp will let you see if the alarm siren and/or light will work properly during the test without producing a false alarm. We explain this in detail in "Completing and Testing the Installation" on Faxback Doc. # 33423. CAUTION: If you connect both an alarm siren and light to the alarm center, they must be connected in parallel and the combined rating of both devices must be 1A or less. The recommended siren and light meet this specification. Using a siren and light together that do not meet this specification could damage the alarm center, siren, and light. STOP! Do not connect the alarm siren and/or light to the alarm center yet. You will connect them while testing the alarm system. CONNECTING AC POWER Use a screwdriver to attach 14-gauge hookup wire to both terminals on the back of the AC adapter, then connect one wire to Terminal 17 and the other wire to Terminal 18 on the alarm center. It does not matter which wire you connect to Terminal 17 or Terminal 18. NOTE: Make sure the AC outlet you use is not controlled by a wall switch. STOP! Do not plug the AC adapter into the AC outlet yet. You will plug it in while testing the alarm system. (SP/EB 5/25/96)
