LOREX LR-MUNZAM Telephone Ringer Relay Switch
LOREX LR-MUNZAM is a telephone ringer relay switch designed to activate external warning or indication devices whenever an incoming call is received on a telephone line.
Once connected to your phone line, the onboard relay can be used to activate an external siren, buzzer, bell, light or similar equipment that will switch on and off in synchronisation with the incoming ringing signal.
The relay is rated to switch loads up to 230Vac or 28Vdc at 3A maximum current and is completely isolated from the telephone line, helping provide safe and reliable integration with external devices.
The board does not affect normal telephone operation and can remain permanently connected to the line. It is powered directly from the phone line itself, so no external power supply is required. It is suitable for use on PSTN (Public Switched Telephone Network) land lines.
