Please note: The Kidde Firex KF30 (previously KF3 / 4899 / H230CT) and KF30R (previously KF3R / 4892 / HR230CT) are replacements for the Kidde 323/9HI and 323/9HILL series and can be electrically interlinked. However, the new models cannot be used on the old base plates for the 323/9HI and 323/9HILL series as they use different style connector blocks. This means that base plates must be swapped over on those stated models and connectors need to be replaced.
