Use the Chuango Keychain Remote Control to easily arm and disarm your Chuango H4 alarm system (with or without sound notification). There is also a handy 24 hour panic button that will instantly trigger the H4 alarm in case of an emergency (even if the system is not armed). Two Chuango Keychain Remote Controls are included.

Signal repeaters repeat the communication signal of any sensors, strobe/sirens, remote controls etc. Signal repeaters can be used in larger applications to enable the alarm control panel to protect a larger premises or location.
