4-Channel Control
Four independent buttons trigger separate relay outputs for multiple doors, gates or switching tasks from one fob.
Reliable 433MHz
Bosch 433MHz transmission delivers stable, everyday handheld operation with a practical working range.
Relay-Based Flexibility
Works with compatible Bosch receivers to drive relay outputs — perfect for automation and simple arm/disarm.
Compact & Pocketable
Slim keyfob format that carries easily on a keyring for convenient daily use.
Which receiver does the HCT-4 need?
It works with compatible Bosch relay-based receivers such as the WE800EV2 and RE005EV2 — the receiver drives the relay output.
How many buttons does it have?
Four channels, each able to trigger a separate relay output for different doors, gates or functions.
What frequency does it use?
433 MHz, the standard Bosch remote-control band in Australia.
Can I use it to arm and disarm an alarm?
Yes, via a relay input on your panel. It is a relay-triggered remote rather than a native RADION alarm fob.
Is it the same as the HCT-4UL?
No — the HCT-4 and HCT-4UL are different Bosch remotes with different receiver compatibility. Match the remote to your receiver.
Does it need a battery?
Yes, it is battery powered and includes low-battery indication on supported versions.
