intro18e and OWNER’S HANDBOOK 2008 M.Y. SUPPLEMENT To be read in conjunction with handbook D121T0324 LSL529 lsl529_oh_USA 08 supp.indd 128/09/2007 01:10:43 ‘08 M.Y. Supplement Vehicle Security Alarm The Lotus Elise/Exige for ‘08 model year onwards is fitted as standard with a PFK 457 immobiliser/alarm which includes the following features: • U.K. approval to Thatcham category 1. • ‘Dynamic coding’ of the transmitter keys; Each time the transmitters are used, the encrypted rolling code is changed to guard against unauthorised code capture. • Passive activation of immobiliser, central locking and alarm system. • Ingress protection using sensing switches on the latches of both doors, the front body access panels, and the engine lid/tailgate. • Selectable cockpit intrusion sensing using a microwave sen- sor. • Self powered siren to maintain protection if the vehicle battery is disconnected. • Personal protection by ‘on demand’ activation of the siren. • Emergency alarm override and transmitter key programming using an alarm/owner specific Personal Identification Number (PIN). Transmitter Keys Two transmitter keys are provided with the car, and combine a mechanical key blade with a three button transmitter unit incorpo - rated into the key head. The mechanical key operates the ignition switch, emergency manual door locks and Elise engine/boot lid. Manual siren, aux. Disarm, mobilise, u nlock Arm & Lock TRANSMITTER KEY ohs128c 2 lsl529_oh_USA 08 supp.indd 228/09/2007 01:10:44 ‘08 M.Y. Supplement The transmitter operates the electronic immobiliser, alarm system and the central locking. The two transmitter keys should be kept separate, and a replacement obtained immediately after any loss to ensure that a spare is always available. The 4-digit code for the mechanical key, the unique serial number of the immobiliser/alarm, and the vehicle owner’s 5-digit alarm Personal Identification Number (PIN), are supplied on plastic tags attached to the key ring of a new vehicle. In order to allow replacement transmitter keys to be ordered, it is essential that these numbers are recorded and kept safely with the vehicle documents. If the codes are not available on receipt of the car, enquire with the dealer immediately. Disarming the Alarm/Unlocking When approaching the car, it is likely that the vehicle is locked and the alarm armed. The alarm red tell tale lamp in the speedometer face will be triple flashing. To disarm the alarm and unlock the doors: - Press the central, unlock, button on the transmitter key. The first press will unlock just the driver’s door. Two presses in quick succession will unlock both the driver and passenger doors. - This command will be acknowledged by a double flash of the hazard lamps. - The engine will be mobilised (see below). - The interior lamp will fade on, and remain lit for up to 2 minutes (if set to the ‘courtesy’ position). - The alarm tell tale will be extinguished. If a door is not opened within 2 minutes, the doors will pas - sively re-lock and the alarm system re-arm. Passive Immobilisation In order to provide a measure of automatic vehicle security, independent of any driver initiative, the system will ‘passively’ immobilise the engine’s cranking and fuel pump circuits after the ignition has been turned off for 40 seconds, or a similar period has elapsed since the last mobilising command. With the ignition off, the alarm tell tale will indicate that immobilisation is in effect by briefly flashing every second. With ignition on, immobilisation is indicated by a continuously lit tell tale. 3 lsl529_oh_USA 08 supp.indd 328/09/2007 01:10:44 ‘08 M.Y. Supplement To mobilise the car (i.e. allow engine starting) with ignition on or off, press once the transmitter centre button; the alarm tell tale will be extinguished. Arming the Alarm/Locking the Doors To lock the doors and arm the alarm, remove the ignition key, close both doors, and check that the engine lid/tailgate and body front access panels are secure: - Press once the raised logo button on the transmitter fob. - This command will be acknowledged by a single flash of the hazard lamps. - Both doors will be locked, the engine immobilised and the alarm system armed. A settling period of 40 seconds must expire before the ingress sensors become active. - The alarm tell tale will repeatedly triple flash. Note: i) If the system is armed when a door is not fully shut, three triple beeps will sound as a warning and the doors will not be locked. Opening a door will not trigger the alarm. ii) If the system is armed when the engine lid/tailgate or a front access panel is not fully closed, three warning double beeps will be heard, and the doors will not be locked. Opening a door in this instance will trigger the alarm. iii) If one transmitter is used to disarm the alarm, and a second transmitter to re-arm, a system test mode will be initiated, and operational variations will occur. Allow an undisturbed period of 2 minutes to elapse to restore normal operation. When fully armed, and after the settling period of 40 seconds has expired, the alarm will be triggered by any of the following actions: - Interruption of the car battery power supply or siren cables. - Energising the ignition circuit (‘hot wiring’). - Opening a door; - Opening the engine lid/tailgate or a front access panel. - Movement detected within the cabin (unless de-selected). If the alarm is triggered, the hazard warning lamps will flash and the wailing siren will sound for a period of approximately 30 seconds before closing down and resetting, ready for any further triggering input. If a trigger is continuously present (e.g. door left 4 lsl529_oh_USA 08 supp.indd 428/09/2007 01:10:44 ‘08 M.Y. Supplement open), the alarm will repeat for a maximum of eight 30 second cycles before excluding the triggering sensor for the remainder of the armed period. To silence the siren, press once the central, disarm button on the transmitter key. If necessary, press a second time …

ID Label/Location Info

457 800 Key Fob Label Location Justification The position chosen for the FCC label is on the main part of the unit under the battery cover. The reasons for this choice are as follows: The battery cover is easily removable by unclipping the cover from the main unit. No special tools are required for screws or any additional fastening devices. The only space available on the outside on the unit is on the removable battery cover. In the event of the cover being left off or lost the FCC qualification would not be evident. For practical and aesthetic reasons the label could not be placed on the front or sides of unit because of limited space and the position of the press buttons. In the position chosen, the FCC Label will be easily seen when the battery cover is removed. The label is positioned such that it can be seen without removing the battery. The Key Fobs are normally supplied with batteries to the new owner when the vehicle for which it is intended is purchased. In the event of a spare or replacement Key Fob being purchased it would be necessary to fit the battery at the time of purchase and the FCC label would then be seen. E. A. B. Ulett Project Coordinator

Operational Description

457 800 TRANSMITTER OVERVEIW . The product is a low power transmitter used to control the vehicle alarm and convenience features. CIRCUIT DESCRIPTION . Power is derived from a single CR2932 Lithium cell. IC 1 is an encoder. It is programmed with the Keeloq algorithm and unique manufacturer’s key. When a switch is pressed the IC outputs the next code in the sequence together with the switch information to pin 6. Tr1 and associated components form a Colpitts oscillator. SAW1 sets the frequency. L1 is an inductor etched onto the PC Board. It is the DC path for the oscillator and also acts as the radiating element. C2 and C3 provide feedback and are resonant with L1. R3 prevents parasitic oscillations. The PWM output from pin 6 of IC1 provides the base bias for the oscillator. The oscillation is turned on and off by this signal. C1 is a de-coupling capacitor. The ground plane on the PC board and the battery provide the ground reference for the radiating element.
