Replace existing installation at an apartment
Please distinguish between your own home and common areas in advance. For work on a shared entrance or cable route, coordination with the appropriate management authority is required. Include existing connections before a proposal assumes free access to a shaft or meter box. For replace existing installation, we first discuss detection zones, access points and who responds to alerts with residents. We determine which parts are still usable and where replacement is really needed. The quality mainly lies in positioning and sun logic; a poorly positioned alarm remains to give false alerts. We also consider how authorized users can arm and disarm the system and know who handles an alarm.
