Owner's manual for the X10 Supervised Security System, Model SC1200 — a console-based wireless home security system with automatic telephone dialer, remote arm/disarm, and light/appliance control.
Owner's manual for the X10 Supervised Security System, Model SC1200 — a console-based wireless home security system with automatic telephone dialer, remote arm/disarm, and light/appliance control.
The X10 Supervised Security System Console with automatic dialer calls neighbors or friends in the event of a break-in. Battery-powered wireless Door/Window Sensors trigger the alarm when a door or window opens; a battery-powered RF Motion Detector protects an indoor area. A Keychain Remote Control arms and disarms the system, and can also turn lights on/off (requires X10 Modules). All sensors and remotes use random digital security coding.
The system supports:
Note: The security functions of this system have not been tested by Underwriters Laboratories.
Choose a central Security Console location with access to a modular telephone jack and AC outlet; it can sit on a shelf/table or be wall-mounted. Plan sensor/detector locations so the RF path to the Console isn't obstructed by large metal objects (e.g. refrigerators) and passes through as few walls as possible. Door/Window Sensors may be hidden behind drapes for discreet installation.
A telephone cord with RJ11 connectors is provided. The Console should ideally have its own phone line; alternatively use the supplied 'T' adapter to share a line with an existing phone. Note: not designed for RJ31X connections. Attach the power supply cord to the connector labeled "power supply" and plug it into an unswitched AC outlet — you must use the included power supply (it contains circuitry for controlling X10 Modules; a standard 8V DC supply will not work).
Open the battery compartment at the top right of the Console and install 4 AA alkaline batteries (not supplied) — no need to disconnect power. An indicator turns on if batteries are low or not installed.
Can sit freestanding on a table/shelf or be wall-mounted using the two slotted holes on the back. If not wall-mounting, insert the included rubber plugs into the slots to tilt the console forward for better display viewing.
After connecting power, the display shows the time with "HOME CONTROL" on the top line. All features except Home Control require Menu mode: press either Menu up/down button, enter the default PIN 0000 (changeable later), then use Menu buttons to step through options 1–9 or press the corresponding number directly.

| 2 | SET CLOCK | Enter time followed by am/pm |
| 3 | PHONE NUMS | Store up to six 16-digit phone numbers |
| 4 | MESSAGE | 1. RECORD your alarm message; 2. REPLAY it |
| 5 | NEW PIN | Enter new 4-digit PIN |
| 6 | MEMORY CLEAR | Clear all Sensors, Remotes, Timers, or Master Clear |
| 7 | OPTIONS | Set Chime On/Off, Siren On/Off, Housecode, Light Code |
| 8 | DELAYS | Set Exit, Entry, Dial, and Answer Delays |
| 9 | SET TIMER | Enter unit code, On/Off times, Daily/Once/Random |
Removing a sensor: at the ZONE screen, press the zone number then CLEAR; confirm YES.
Mounting tips: mount as high as possible at the top of the door/window; ensure the sensor and magnet arrows face each other and separate cleanly when opened. For two doors/windows close together, use an additional magnetic switch pair (sold separately) to register as its own zone. Set the internal DELAY slide switch to MIN for instant alarm triggering (windows) or MAX to trigger after the entry delay when armed Away (doors).
The console's 1–32 zone display shows open (steady on), problem (slow flash), or bypassed (fast flash) zones. Attempting to arm with an open/problem zone triggers continuous beeping; press Clear to bypass and move to the next problem zone.
Installation: mount at 5–6 ft. height using the included bracket, angled slightly downward. Set the rear slide switch to position 1 (instant trigger, max sensitivity) or position 2 (triggers after two detected movements).
Testing: set switch to position 1, press and hold TEST about 1 second (LED flashes twice), wait 20 seconds to settle, then walk in front of it — the LED lights on each detected movement. Press TEST again to return to normal mode (or wait ~2 minutes for automatic return).
Two additional hard-wired magnetic contact switches can be connected as zones 31 and 32 (treated as delayed zones with exit/entry delays when armed Away). Remove the shorting link before installing hard-wired contacts. Combined with wireless sensors, total zones supported: 30 wireless + 2 hard-wired = 32.
Menu > SET CLOCK (option 2): enter time, then am/pm, then OK.
Menu > PHONE NUMS (option 3): select PHONE 1–6, enter up to 16 digits (Off/pm inserts a pause), press OK.
Menu > MESSAGE (option 4) > RECORD: speak your message into the Console's microphone (12 seconds max), e.g. "There's an alarm in progress at [address]; please press any button on your touch-tone phone to listen in." Select REPLAY to play it back. Note: messages cannot be recorded remotely via telephone.
Menu > NEW PIN (option 5): enter a new 4-digit PIN and press OK. Choose something memorable — if forgotten, contact x10.com for reset instructions.
Menu > MEMORY CLEAR (option 6): CLEAR ALL SENSORS, CLEAR ALL REMOTES, CLEAR ALL TIMERS, or MASTER RESET (returns immediately to Home Control).
Menu > OPTIONS (option 7):
Menu > DELAYS (option 8), values in seconds up to 99:
Menu > SET TIMER (option 9): enter a Unit Number (1–16), then an ON time (am/pm) and OFF time, then choose DAILY, ONCE ONLY, or RANDOM (varies time within the programmed hour). Up to 12 timer "pairs" total. Cycle through stored timers with Menu up/down; press Clear on a displayed timer to delete it, or OK to replace it.
Attempting to arm with an issue shows one of: OPEN ZONE # (door/window open), PROBLEM ZONE # (sensor hasn't reported in 4 hours), or TAMPER ZONE # (sensor cover open). Press Clear (Bypass) to skip that zone and continue arming; a bypassed zone stays bypassed until the system is disarmed. If the Console's own tamper door is open, it must be closed before arming.
Arming (Home or Away) and then opening a protected door/window, triggering a Motion Detector (Away mode), or pressing Panic (Arm + Disarm together on the Keychain remote) trips the alarm: a loud siren sounds and configured security lights flash.
With one or more Lamp Modules installed, press the module's assigned number button on the Console (while displaying HOME CONTROL) then On/Off to control that light. The Keychain Remote's A/B buttons control lights set to the Console's Security LIGHTCODEs.
Rating: Lamp Modules support incandescent lamps up to 300W only — not fluorescent, energy-saving, low-voltage, or dimmer-controlled lamps. Caution: Do not connect appliances (coffee pot, heater) to a Lamp Module — use an Appliance Module instead to avoid damage or fire hazard.
Calling home: the Console answers and says "Please enter PIN." Enter your PIN via touch-tone; it confirms "PIN accepted" or says "Error."
If you own an answering machine: the security system will not answer if the machine (or a person) picks up first — wait for the outgoing message to finish, then enter your PIN as usual. Note the answering machine will record any touch tones and the security system's spoken responses.
| Problem | Solution |
|---|---|
| System does not arm | Check the Remote's indicator lights when pressing ARM; replace batteries and reregister if needed. |
| Console displays PROBLEM + zone number when arming | A sensor hasn't reported in 4 hours — check its batteries, or check for an open door/window. Press CLEAR to bypass the zone, then ARM, to arm the rest of the system. |
| Repetitive trouble alarm when trying to arm | Press DISARM and check each sensor / closed doors and windows, or press CLEAR during the alarm to bypass the problem zone, then arm again. Check TAMPER zones' sensor covers, and the Console's own lid. |
| Alarm trips when entering before you can disarm | Arm the system in AWAY mode to get an entry delay. |
| Lights won't turn on/off from the Keychain Remote | Confirm the SECURITY LIGHT code is set correctly; check the light's switch and bulb; try plugging the Module into another outlet; verify the Remote's indicator and Module dial settings. |
| Door/window opened but alarm doesn't trip | Confirm the system is armed; test the sensor's internal TEST button and check its indicator; replace batteries/reinstall if the indicator doesn't light. |
| Appliances turn off during an alarm | The system flashes lights by repeatedly transmitting the SECURITY light codes; any Appliance Modules on the same codes will also toggle. Use separate codes if this is undesired. |
| No beep from Console when registering a Remote | Re-initialize the remote (hold ARM 3–4 sec). |
| No beep when registering a Door/Window Sensor or Motion Detector | With the system disarmed, confirm it chimes on sensor TEST (or alarm trips on Motion Detector TEST while armed) — if not, reregister the device. |
| Battery indicator on Console is lit | Replace the 4 AA backup batteries (provides ~12 hrs backup); replace at least yearly. |
| Lost a remote control | Clear and reinitialize the complete system to prevent unauthorized use of the lost remote. |
| System arms/disarms by itself | A neighbor may have a compatible system on the same RF codes; reinitialize the complete system to select different codes. |
| Alarm cause remains on display after disarming | Arm and disarm again from a remote, or disarm via the Console menu/PIN, to clear it. |
