The 458RL is a remote upgrade alarm that meets with Thatcham CAT 2 to 1 standards. It’s similar to the 446RLi Premium, but is designed for vehicles that have an existing immobiliser, yet require remote locking.
It comes with a 4 button remote that is well designed. Has lock, unlock and boot pop buttons as well as one that will turn the hazard lights on solid for two minutes *, which can be useful for night vision around the car.
It also allows for silent arming with the remote plus gives you the option to isolate the ultrasonic sensors, or addition wireless sensors (see below) on arming.
Fixed Eye Ultrasonic Sensor
A fixed eye ultrasonic sensor come as standard. Whilst not as factory looking as the Cobra Ultrasonics the sensor is still neat and has a red LED build into the centre of the housing.
The Battery back-up siren is the same as the one found on the 446RLi Premium and 695CAN.
It’s a true digital siren which means it does not require an over-ride key. It can therefore be place in a hard to access location which can make it effective unlike most of the 5 star alarm sirens that the likes of AVS and Mongoose still offer.
Wireless Sensor Options
A great alarm from an installation point of view.
From an installation point of view the 458RL is great to work with. It has built in central locking relays, supports vehicles that have selective unlocking as well as those that require a double lock pulse to dead lock.
It’s also has some cleaver ways to flash the hazard light as it support conventional left and right power blinker outputs, as well as single wire hazard level and hazard logic.
