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 additional wireless sensors (see below).
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 backup 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 override key. It can, therefore, be placed 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 deadlock.
It also has some clever ways to flash the hazard light as it supports conventional left and right power blinker outputs, as well as single wire hazard level and hazard logic.
