Safety Precautions
Radionics (now Bosch) panels may be outdated and old-fashioned, but they were robust panels. Unfortunately, they’re not DIY friendly; you need a programmer in order to make changes such as adding/delete zones.
Command 4 is used to acknowledge trouble conditions on 6112 and related systems, and to silence beeping keypads. Furthermore, it can be followed up with additional digits for diagnostic functions within either system or keypad.
Entering Command 4 and 5 together, for example, can reset a 2-wire smoke detector loop. Consult the burglar alarm manual or fire alarm manual for further instructions regarding this and other Command 4 functions. Commands 7 and 8 bypass or unbypass specific points on the system temporarily arming around faulted points until service can be scheduled.
Operation
Radionics panels can be difficult to navigate without proper knowledge. Unlike most alarm panels, there’s no “jumper”, “special key combination”, replacement chip”, or reset button that can reset them back to their default state. Most Radionics panels feature datalock technology; popular programmers include the 5100/5200. Earlier 4112/6121 panels don’t feature datalock but the only way to program them with RPS or handheld programmers and compatible keypads may also be hard to locate.
Maintenance
Radionics alarm panels differ from most alarm panels in that they do not contain jumpers, key combinations, replacement chips, or special passcodes for resetting them to default. Therefore, in order to regain access you will require either the original installing dealer’s programmer, or downloading and uploading an account directly through RPS or another programer (such as handhelds like 5100/5200 handhelds). A dead lithium battery or lost datalock could potentially prevent accessing it, however these situations can typically be remedied either by Norb at Obsolete Radionics or myself depending on its vintage and type.
