Covert lighting system

System description and operation - 2005 Model Year vehicles

WARNING:
^ Unauthorised modifications to this system are not permitted. The manufacturer does not accept any responsibility for this system in the event that unapproved modifications are made.
^ INJURY COULD OCCUR:- High Voltage capacitor needs discharging, WAIT 5 MINUTES after switching system off before attempting service. Warranty void if seal is broken.


System power supply specifications









The covert lamps are fitted behind the front grille, and are secured to a mounting bracket using two screws.

The strobe light system fitted to the Armoured Range Rover is available with front only (2-way) or front and rear (6-way) strobe lights depending on customer requirements.

The power supply module for the system is located in the rear luggage area behind the panel in the RH rear corner. Power is provided by a fused (15 Amp) connection from the auxiliary power supply (from the split-charge system, also located behind the panel in the RH rear corner of the luggage area) to the dashboard mounted on/off switch.

For the 2-way circuit, the red wire from the strobe power supply is connected to the other side of the on/off switch.

For the 6-way circuit, the red wire from the strobe power supply is connected to the fused supply side of the dashboard mounted on/off switch. The yellow, green and blue wires from the strobe power supply unit connect to the other terminal of the dashboard mounted switch. The black, white, grey and orange wires are connected to ground.

These wiring configurations give a flash rate of 140 FPM (Flash Per Minute). The low power mode for nighttime operation is not available.

The system does not require any routine maintenance.

The covert lamps system consists of two grille mounted Blue LED lamps, a switch mounted on the facia and a flasher relay mounted in the rear right hand side of the vehicle behind the trim. The lamps execute an alternating triple flash pattern.

The system is powered via Fuse 3 (5 amp) of the auxiliary fuse box mounted in the rear right hand side of the vehicle. A feed is provided to the switch (C3268) on a PG wire. With the switch in the on position a feed is provided to the Flasher Relay (C1890) on a UR wire. The Flasher Relay has two outputs, which feed the left and right hand Blue LED lamps alternately. The Flasher Relay is grounded (C1891) on an N wire. The left hand lamp is fed from terminal A(C2307) via a US wire; the right hand lamp is fed from terminal B (C2607) via a UG wire. Each lamp is grounded via an N wire. A feed for the switch illumination is provided on a SR wire, and is grounded via an N wire at C556.

Alternating flashing headlamps
The Headlamp Flash system utilises a feature built in to the Lighting Control Module. The feature requires enabling with Testbook/IDS. When the feature is enabled, an LCM output (C2040-46) requires switching to ground to activate the alternately flashing lamps. A switch for this feature is mounted on the facia.

LCM output (C2040-46) is connected to the switch (C3267) on an UW wire. With the switch in the on position, the output is grounded on a B wire. An ignition feed is provided on a GY wire to the switch to illuminate a status lamp when in the on position. A feed from the panel illumination circuit is provided on an SR wire to illuminate the switch.

System description and operation





In order to activate it, use the green switch button on / off.

Communicate as follows :
From the inside to the outside : press the yellow button while speaking. Once you have released it, the outside listening is permanent.

If you want to increase the interior volume of the loud speaker, turn the potentiometer clock wise.

The amplifier is located the rear luggage area inside the 'options box'.

Microphone for the interior





The microphone inside is situated near the driver.

Microphone for the exterior





The microphone outside is situated near the rear view mirror passenger.

The outside loudspeaker is situated under the body.

The inside loudspeaker is situated under the dashboard.

Siren

Description - 2005 Model Year vehicles





The siren system consists of a siren fitted beneath the battery carrier, an amplifier mounted under the spare wheel access cover, a speaker mounted in the left hand side of the engine compartment and a switch mounted in the additional switch pack on the fascia. The system is connected together and integrated into the vehicle with a link harness.

Operation - 2005 Model Year vehicles
An electrical feed from the auxiliary battery positive terminal (C2175-2) is supplied on a red wire to the auxiliary fuse box mounted the rear right hand side of the vehicle.

Fuse 2 (C0632-2) provides a feed to the Power Relay (C0901-30) on a P wire. The siren 'arm' signal (C3128-6) is taken to the Relay-Siren C3129-30 on a G wire. The arm signal is grounded at the amplifier C3128-4 on a B wire via the Relay-Siren.

When the siren switch (C1779) is activated an ignition feed is provided to the power relay coil (C0901-85) on a GW wire, and to the Relay-Siren (C3129-85) on a GW wire. The coils are earthed on N wires. The Power-Relay (C0901) is pulled in connecting a feed to the Siren amplifier C1627 on a PR wire. The amplifier ground connection (C1628) is taken to C1661-0 via an N wire.

At the same time, the Relay-Siren (C3129) is pulled in, and the siren 'arm' signal has its path to ground removed. The siren is now 'armed' and under the control of the vehicle horn switch. When the vehicle horn button is pushed the siren starts in wail mode. A further push toggles the siren into yelp mode. Two pushes in quick succession will cancel the siren, as will returning the siren switch to the off position.

The toggle function is enabled via the vehicle horn circuit connected to the amplifier C3128-15 on a PS wire. The siren speaker (C1771) is connected to the amplifier C3128 via an N and NWwire. A feed for the switch illumination is provided on a SR wire, and is grounded via an N wire at C1661.

Description - 2006 Model Year vehicles
The Siren system consists of a facia mounted switch, a speaker mounted in the engine compartment and an amplifier and two relays mounted in the rear right hand side of the vehicle behind the trim. The system is powered via Fuse 2 (25 amp) of the auxiliary fuse box mounted in the rear right hand side of the vehicle.
