installation points to remember This product represents many years of research and development. It is very sophisticated and should be installed by experienced security installers only. Please do not attempt installation of this product without reading this guide. The system has been designed to provide the ultimate in security, coupled with limitless convenience and expansion options.
deciding on component locations locations for the siren Some things to remember when mounting the siren: ■ Keep it away from heat sources. Radiators, exhaust manifolds, turbochargers, and heat shields are all things to avoid. ■ Mount it where a thief cannot easily disconnect it, whether the hood is open or shut. Both the siren and its wires should be difficult to find. This usually involves disguising the wire to look like a factory harness.
■ The higher the control module is in the vehicle, the better the transmitter range will be. If you put the control module under a seat or inside a metal dashboard, range will suffer. ■ Some good control module locations: Above the glove box, inside the center console, above the underdash fuse box, above the radio, etc. locations for valet/program switch Ensure that the location you pick for the switch has sufficient clearance to the rear. The switch should be well hidden.
locations for the status LED Things to remember when positioning the Status LED: ■ It should be visible from both sides and the rear of the vehicle, if possible. ■ It needs at least 1/2-inch clearance to the rear. ■ It is easiest to use a small removable panel, such as a switch blank or a dash bezel. Remove it before drilling your 9/32-inch hole. ■ Use quick-disconnects near the LED wires if the panel is removable. This allows mechanics or other installers to remove the panel without cutting the wires.
finding the wires you need Now that you have decided where each component will be located, you’re going to find the wires in the car that the security system will be connected to. IMPORTANT! Do not use a 12V test light to find these wires! All testing described in this manual is described using a digital multimeter. obtaining constant 12V We recommend two possible sources for 12V constant: The (+) terminal of the battery, or the constant supply to the ignition switch.
4. Turn the ignition key switch to the run position. If your meter reads (+)12V, go to the next step. If it doesn’t, probe another wire. 5. Now turn the key to the start position. The meter display should stay steady, not dropping by more than a few tenths of a volt. If it drops close to or all the way to zero, go back to step 3. If it stays steady at (+)12V, you have found an ignition wire.you have found an ignition wire.
How to find a door pin switch trigger wire with your multimeter: 1. Set to DCV or DC voltage (12V or 20V is fine). 2. In most cars, fasten the (+) probe of your meter to (+)12V constant. 3. Probe the wire you suspect of being the door trigger wire. If the meter reads (+)12V when any door is opened, you have found a trigger wire. NOTE: Make sure the wire you use “sees” all the doors! Some newer GM vehicles lack standard-type pin switches.
making your connections When connecting the security system’s wires to the wires in the vehicle it is important that the connections are tight and no bare wire is exposed. In this section, two types of connections are described that may be used to connect the wires from the security system into the vehicle’s wiring. Both types of connections are electrically acceptable if made correctly. Other types of "tap-in" connections, such as T-Taps are not acceptable. solderless butt connections 1.
solder connections 1. Using your wire strippers and razor knife, strip approximately 1/2-inch of insulation off the wire to be connected to, without cutting the wire. Stripped Vehicle Wire 2. Twist the security module’s wire around the bare section of the vehicle’s wire. Vehicle Wire Module Wire 3. Solder the bare connection thoroughly using rosin core solder. Vehicle Wire Module Wire 4. Completely insulate the connection with electrical tape. 12 © 1999 Directed Electronics, Inc.

primary harness wire connection guide This guide describes in detail the connection of each wire. Also included are possible applications of each wire. This system was designed with the ultimate in flexibility and security in mind. Many of the wires have more than one possible function. Please read carefully to ensure a thorough understanding of this unit. H1/1 ORANGE (-) ground-when-armed output This wire supplies a (-) ground as long as the system is armed.
H1/3 WHITE/BLUE 200 mA (-) channel three output This wire provides a 200 mA (-) output whenever the transmitter button(s) controlling channel three is pressed. This output can be programmed to provide the following type of outputs (see System Features Learn Routine section of this guide): ■ A validity output will send a signal as long as the transmission is received. ■ A latched output will send a signal continuously when channel three is pressed and will continue until channel three is pressed again.
H1/4 BLACK/WHITE 200 mA (-) domelight supervision output Connect this wire to the optional domelight supervision relay as shown below: IMPORTANT! This output is only intended to drive a relay. It cannot be connected directly to the domelight circuit, as the output cannot support the current draw of one or more bulbs. H1/5 GREEN (-) door trigger input Most vehicles use negative door trigger circuits. Connect the green wire to a wire which shows ground when any door is opened.
H1/7 VIOLET (+) door trigger input This wire is used in vehicles that have a positive (+) switched dome light circuit . Connect the violet wire to a wire that shows (+)12V when any door is opened, and ground when the door is closed. H1/8 BLACK (-) chassis ground connection Connect this wire to bare metal, preferably with a factory bolt rather than your own screw. Screws tend to either strip or loosen with time.
H1/9 YELLOW (+) ignition input Connect this wire to the (+)12V ignition wire. This wire must show (+)12V with the key in Run position and during cranking. Take care to insure that this wire cannot be shorted to the chassis at any point. H1/10 BROWN (+) siren output Connect this to the red wire of the siren. Connect the black wire of the siren to (-) chassis ground, preferably at the same point you connect the control module’s black ground wire.
IMPORTANT! Never use this wire to drive anything but a relay or a low-current input! The transistorized output can only supply 200 mA of current. Connecting directly to a solenoid, motor, or other high-current device will cause it to fail.
door lock harness (H2) wire connection guide type A: (+) 12V pulses from the switch to the factory relays The system can control a Type A system directly, with no additional parts. The switch will have three wires on it, and one will test (+)12V constantly. The others will alternately pulse (+)12V when the switch is pressed to the lock or unlock position.
type B: (-) pulses from the switch to the factory relays This system is common in many Toyota, Nissan, Honda, and Saturn models, as well as Fords with the keylessentry system (some other Fords also use Type B). The switch will have three wires on it, and one wire will test ground all the time. One wire will pulse (-) when the switch locks the doors, and the other wire will pulse (-) when the switch unlocks the doors. This type of system is difficult to mistake for any other type.
type C: reversing polarity Interfacing with a reversing polarity system requires either two relays or one 451M (not included). It is critical to identify the proper wires and locate the master switch to interface properly. Locate wires that show voltage on lock and unlock. Cut one of the suspect wires and check operation of the locks from both switches. If one switch loses operation in both directions and the other switch operates in one direction only, you have located one of the target wires.
type D: after-market actuators In order for this system to control one or more after-market actuators, a 451M or two relays (optional) are needed. Vehicles without factory power door locks require the installation of one actuator per door. This requires mounting the door lock actuator inside the door. Other vehicles may only require one actuator installed in the driver's door if all door locks are operated when the driver's lock is used.
type E: mercedes-benz and audi (1985 & newer) Door locks are controlled by an electrically activated vacuum pump. Some Mercedes and Audi models use a Type D system. Test by locking doors from the passenger key cylinder. If all the doors lock, the vehicle's door lock system can be controlled with just two relays (optional). The control wire can be found in either kick panel and will show (+)12V when doors are unlocked and (-) ground when doors are locked. To interface, see diagram below.
type F: one-wire system This system usually requires a negative pulse to unlock, and cutting the wire to lock the door. In some vehicles, these are reversed. It is found in late-model Nissan Sentras, some Nissan 240SX, and Nissan 300ZX 1992-up. It is also found in some Mazda MPV's and some Mitsubishi's. One relay (optional) is used to interface to this type of system as follows: © 1999 Directed Electronics, Inc.
on-board doubleguard shock sensor There is a Doubleguard® shock sensor inside the control unit. Adjustments are made via the rotary control as indicated above. Since the shock sensor does not work well when mounted firmly to metal, we recommend against screwing down the control module. The full trigger of the on-board shock sensor reports zone 2. (See Table of Zones section of this guide.
H3/2 VIOLET/BLACK (-) 200 mA channel 4 output This wire supplies a 200mA (-) output whenever the button(s) controlling Channel Four is pressed and will continue until the button(s) is released. This output can be used to control optional accessories. IMPORTANT! Never use this wire to drive anything but a relay or a low-current input! This transistorized output can only supply 200 mA (-), and connecting directly to a solenoid, motor, or other high-current device will cause the module to fail.
four-pin optional sensor harness RED wire The red wire supplies constant power to the optional sensor. BLACK wire The black wire supplies ground to the optional sensor. BLUE, GREEN wires The blue and green wires are multiplex inputs. They are both tied to the same zone. If an input of less than 0.8 seconds is supplied to either wire the Warn-Away® response will occur. An input longer than 0.8 seconds to either wire will initiate the triggered sequence and report zone 4.
system features learn routine The System Features Learn Routine dictates how the unit operates. It is possible to access and change any of the feature settings using the Valet®/Program switch. However, this process can be greatly simplified by using the optional Personal Computer Interface, or DEI® Bitwriter™. Any of the settings can be changed and then assigned to a particular transmitter, up to four, a feature called Owner Recognition.
once a feature is programmed ■ Other features can be programmed. ■ The Learn Routine can be exited if programming is complete. to access another feature Press and release the Valet®/Program button the number of times necessary to advance from the feature you just programmed to the next one you want to program. Then press the Valet®/Program button once more and hold it.
feature descriptions 1 ACTIVE/PASSIVE ARMING: When active arming is selected, the system will only arm when the transmitter is used. When set to passive, the system will arm automatically 30 seconds after the last door is closed. To alert the consumer of passive arming, the siren will chirp 20 seconds after the door is closed. This provides the consumer with an audible warning prior to the system actually arming. At the 30 second mark, the system will arm but the siren will not chirp.
10 VALET® PULSE COUNT 1-5 PULSES: The system can be programmed to count the number presses of the Valet® switch before disarming the security system. The factory default setting is one pulse. The unit can be set for 2 to 5 pulses using the Channel Two button (or disarm only button on an OEM transmitter) to select the setting. Ghost Switch™ Option: For added security, the GRAY wire on the two-pin Valet®/Program button can be connected to any switch in the vehicle that provides a positive (+) momentary pulse.

WIRE COLOR Press the transmitter button: While holding the Valet®/Program button, press the button from the transmitter that you wish to assign to that channel. The unit will chirp indicating successful programming. It is not possible to teach a transmitter button to the system more than once.
table of zones When using the diagnostic functions, use the Table of Zones to see which input has triggered the system. It is also helpful in deciding which input to use when connecting optional sensors and switches. Zone Number Trigger Type Input Description One Instant H1/6 BLUE wire.

rapid resume logic This DEI® system will store its current state to non-volatile memory. If power is lost and then reconnected the system will recall the stored state from memory. This means if the unit is in Valet® mode and the battery is disconnected for any reason, such as servicing the car, when the battery is reconnected the unit will still be in Valet® mode. This applies to all states of the system including arm, disarm, and Valet® mode.
■ The Valet® switch doesn’t work. Is it plugged into the correct socket? (See Plug-In Harnesses section of this guide.) Check the System Features Learn Routine for the programmed Valet® pulse count. (See System Features Learn Routine section of this guide.) ■ Status LED doesn’t work. Make sure that it is plugged in. (See Plug-In Harnesses section of this guide.
