SERVICE INFORMATION

Because replacement Saab Guard Alarm modules are no longer available, a kit containing a modified Alpine alarm module has been developed to permit repair of cars equipped with the Saab Guard (Cobra) system. The Alpine kit, P/N 02 46 512, supersedes the Saab Guard module P/N 02 70 520, and is applicable to the following models:

• 1985-90 Saab 900 3- and 4-door Models (accessory installation)
• 1986-90 Saab 900 Convertible Models (o.e.m. installation)
• 1986-88 Saab 9000 Models (accessory installation)

This replacement Alpine kit has been modified to permit disarming with the ignition switch in the same manner as the Saab Guard alarm. However, the ability of the Saab Guard system to disable the alarm by quickly cycling the ignition key is NOT possible with the modified Alpine kit. This modified module uses a microphone to detect glass breakage (no motion sensor is supplied) and since it is not compatible with the valet switch and starter disable relay of the standard Alpine alarm. These items are not supplied with the kit.

If the kit is used to replace a Saab Guard alarm fitted with the optional remote disarm feature, remote transmitters, an antenna and a ROM-chip kit may be added to the modified Alpine replacement kit in order to add remote arming and disarming capability. However, it may be more cost effective to purchase the complete Alpine accessory kit if the customer desires this feature.

SERVICE PROCEDURE

To replace a Saab Guard Installation equipped with the remote disarm accessory, the complete Alpine Accessory Alarm kit (02 46 538) can be used with the following installation procedure as an addendum to the complete kit instructions. It is also possible to add remote control operation to the replacement module kit by adding the following parts:

• Remote Transmitters (qty. 2) ..... 02 46 165
• Transmitter pouches (qty. 2) ..... 02 46 215
• Antenna .......................... 02 46 280
• 3-ROM chip kit ................... 02 46 322

INSTALLATION PROCEDURE - 1985-90 SAAB 900

1. Remove the original Saab Guard module from under the rear seat. If the module was fastened to the floor using screws, re-install the screws to seal the holes.
2. Remove access cover from alarm module. Set switch 1 to "active" (on/up position) or "passive" (down position) arming per customer's requirements. Set switch 2 to the same position as switch 1. See Fig 3 .
   Fig 3: Setting Arming Mode

   
   NOTE: To control the alarm with the ignition key, set the switches to "Passive". If the customer chooses to use the optional remote transmitters, set the switches to "Active".
3. Mount bracket on module using two machine screws. See Fig 4 .
   NOTE: For -1988 model, proceed to step 7. For Convertible models, proceed to step 8.
   Fig 4: Mounting Bracket on Module

   
4. On 1989- models, a 10-pin test socket and bracket must be moved to the right a distance 55 mm.
5. Using the bracket as a template, drill two 7mm (9/32") holes as shown in Fig 5 .
6. Mount bracket with existing hardware.
   CAUTION: When remounting the bracket, be sure the plastic fuel lines are not pinched between the bracket and seat beam.

9. Mount microphone bracket in the center of the seat pivot rail. Do not tighten completely at this time. See Fig 8
   Fig 8: Mounting Microphone Bracket

   
10. For Convertible models it is not possible to mount the microphone to the seat pivot rail. It can be mounted instead to the vertical carpet surface in the same general area using a shop-supplied sheet metal screw and speed nut.
11. Cut a 1" slit in the carpeting at the base of the seat beam to route wires to module location.
12. If a LED is mounted in the left front speaker grille proceed as follows:
    1. M85-M88 All Models and M89 (except CV):
       • Connect the blue wire from the LED to the violet wire from the Alpine harness.
       • Connect the violet wire from the LED to the black/red wire from the Alpine harness.
    2. M89-90 Convertible: The original LED was supplied with 12 volts directly from Fuse 24 (See Service Manual Sec. 3:2, 1989-90, p. 302). This method is incompatible with the Alpine module.
       • Remove the LH front speaker grille.
       • Unplug the violet wire from the LED in the grille and connect the short lead from the LED to ground.
       • Unplug the blue lead to the LED and connect the short lead from the LED to the violet wire which goes back to the alarm module. Make sure that the violet wire is connected to pin 10 of the large Alpine module connector. (Pin 10 is pulsed, positive output to the LED.)
       • Tape over the end of the long blue wire disconnected from the LED since it leads back to Fuse 24.
         NOTE: ALARM HARNESS CONNECTION (see additional steps for late M89 and M90 Convertibles)
13. Connect 8-pin plug of alarm harness (supplied) to 8-pin car alarm plug located under rear seat beam.
14. Route alarm harness along seat beam to module location.
15. Plug microphone lead into module.
16. If optional remote transmitters are being used, plug the antenna mast into module at this point. Bend mast at right angle to module so that it points towards rear of car.
17. Plug 12-pin connector of alarm harness (supplied) into connector marked "Main" and 6-pin connector of harness into connector marked "Sensor" on module.
18. Secure module to tunnel with two water-proof mounting screws in holes drilled in step 25.
19. Connect car battery.
20. Test all alarm system operations.
21. Fold rear seat back into place. Ensure that it latches securely.
22. Position microphone bracket so that it faces forward with seat in folded position. Tighten microphone bracket into place.

WIRING FOR LATE - M89 AND M90 CONVERTIBLE MODELS

1. Cut and transfer the wires from the 12-pin Saab Guard connector to a new 8-pin connector, P/N 91 24 090, using female pins, P/N 91 24 090. The connections should be made as follows:
   CONNECTOR CHANGES
   
   

   12-Pin Plug Location	Wire Color	Function	8-Pin Plug Location

TESTING ALARM FUNCTION (ALL MODELS)

1. Arming Mode Standard: The system will arm automatically when the ignition is turned off and the last door is closed (also known as "passive arming"). Optional: The system can be armed using optional remote control transmitters ("active arming").
2. Disarming Standard: The system can be disarmed by unlocking the car and turning the ignition switch to the "on" position. Optional: The system can be disarmed using the optional remote transmitter.
   NOTE: If the batteries in the transmitter are too weak, the alarm can still be disarmed by turning the ignition switch to the on position.
3. Entry Delay Standard: The entry delay time is set to 25 seconds for "passive arming" and is not adjustable.
4. Exit Delay Standard: The exit delay time is set for 20 seconds after the interior lights go out. If a door or the trunk is opened during this time, the timer will start counting all over again when the last door is closed.
5. Delayed Door Monitor Standard: The system will not monitor the door circuits for the initial 45 seconds after the alarm is armed.
   NOTE: If you are testing an Alpine alarm system in the "active mode" and you open a door before this 45 seconds has elapsed, the siren will not sound until the 45 seconds has passed.
6. Microphone Sensitivity Standard: A high/low switch is provided on the module for adjusting the sensitivity. Under all but the most extreme conditions, the "high" position should be suitable.
7. Siren Duration Standard: The siren will sound for 60 seconds when the alarm has been tripped. After completing this cycle the control unit will reset and respond to any new sensor inputs. If the original sensor input is still active, the siren will stop for 5 seconds and then continue to sound. After 10 minutes the alarm will ignore the continuously activated sensor until the system has been disarmed and re-armed again.
