Motion detectors indoors form the second layer, well-considered arming zones the third \u2014 at night, for instance, only the envelope, so that you can move about freely. This logic follows proven VdS principles and works more reliably than any retrofit kit.<\/p><\/div><div class=\"pcard reveal\"><h3>Part of the house, not an island<\/h3><p>Linked into KNX, the alarm system becomes part of the house: on an alarm the shading goes up, the lighting goes to full inside and out, the camera image appears on your phone. While you are away, the house simulates occupancy with realistic lighting and shading patterns. And the window contacts do double duty \u2014 they report open windows to the heating as well.<\/p><\/div><div class=\"pcard reveal\"><h3>Quiet instead of false alarms<\/h3><p>A system that goes off for no reason gets switched off \u2014 and then protects nobody. So we put planning time into the operating logic: arming by fingerprint or code, automatic disarming on authorised entry, clear acknowledgement. Good sensors and careful configuration keep the false alarm rate low. The aim: a system you trust and therefore use consistently.<\/p><\/div><\/div>\n<\/div><\/section>\n<section class=\"nvs pad\" style=\"padding-top:0\"><div class=\"wrap\">\n  <div class=\"sec-h\"><span class=\"eyebrow\">Two starting points<\/span><h2>Planned in at shell construction, or retrofitted with a sense of proportion<\/h2><\/div>\n  <div class=\"ngrid\">\n    <div class=\"ncard a reveal\"><span class=\"nlab\">New build<\/span><h3>The best moment: the shell construction phase<\/h3><p>Contacts disappear into the window frame at the factory, cables run where they should, the control unit has its place in the technical room.<\/p><ul><li>Magnetic contacts integrated at the factory<\/li><li>Window order agreed with the window manufacturer<\/li><li>Wired, battery-free, tamper-proof<\/li><li>Control unit in the technical room<\/li><\/ul><\/div>\n    <div class=\"ncard b reveal\"><span class=\"nlab\">Existing &amp; listed buildings<\/span><h3>Properly retrofitted<\/h3><p>A sound concept comes about without shell construction too: wired where routes exist \u2014 good wireless technology where cabling would be out of proportion.<\/p><ul><li>Cable and wireless combined<\/li><li>Listed building fitted out by wireless<\/li><li>Manor house Cologne: alarm in a listed building<\/li><li>The logic counts, not the transmission method<\/li><\/ul><\/div>\n  <\/div>\n<\/div><\/section>\n<section class=\"gew\"><div class=\"wrap\">\n    <div class=\"sec-h\"><span class=\"eyebrow\">Alarm &amp; intruder protection<\/span><h2>An alarm system nobody arms protects nothing at all.<\/h2><p>Most systems fail not because of the burglar but because of themselves: after the third false alarm at three in the morning the system stays permanently disarmed, and from then on it is decoration. So we plan intruder alarm systems from everyday life outwards \u2014 which areas, which detectors, which form of arming suit people who come home late, keep dogs and like to leave the terrace door open. And we mesh them with lighting, shading, cameras and access control instead of putting yet another island into the house.<\/p><\/div>\n    <div class=\"gwgrid\"><div class=\"gwcell reveal\"><span class=\"gwnum\">01<\/span><h3>The envelope before the interior<\/h3><p>We monitor the shell first: every window, every door, roof windows, light wells, side entrances. Interior monitoring comes on top as the second layer. The advantage is that it works in daily life \u2014 you live in the house and still arm the system, because the alarm sits at the fa\u00e7ade and not in the living room.<\/p><\/div><div class=\"gwcell reveal\"><span class=\"gwnum\">02<\/span><h3>Opening and bolt contacts<\/h3><p>Magnetic contacts report the open window, bolt contacts additionally report that it is actually locked. On lift-and-slide units and slim frame profiles we settle the contact position and the cable route early with the window manufacturer. Nothing gets routed out of a four-metre sliding door once it is installed.<\/p><\/div><div class=\"gwcell reveal\"><span class=\"gwnum\">03<\/span><h3>Glass breakage on large areas<\/h3><p>Floor-to-ceiling fixed glazing cannot be opened, so it needs monitoring of its own. Structure-borne sound detectors on the pane pick up the break directly, acoustic detectors pick up the frequency pattern in the room. The build-up of the pane, laminated safety glass and the bonding surface decide the type of detector, its position and the area it covers.<\/p><\/div><div class=\"gwcell reveal\"><span class=\"gwnum\">04<\/span><h3>Motion detectors with pet immunity<\/h3><p>Dual detectors combining infrared and microwave, curtain lenses along the glazed fronts, a defined mounting height and detection direction. Dog and cat stay below the trigger threshold. An open fire, underfloor heating and moving curtains we deliberately plan out of the detection field, rather than taping over lenses later.<\/p><\/div><div class=\"gwcell reveal\"><span class=\"gwnum\">05<\/span><h3>Tamper, fault, standby power<\/h3><p>Cover and removal contacts on every device, monitored lines with an end-of-line resistor, and with wireless, encrypted transmission with link supervision and jamming detection. On top of that, battery back-up with a defined standby time and charge monitoring. Router, switch and recorder run off the uninterruptible supply as well, otherwise the signalling path dies with the incoming supply.<\/p><\/div><div class=\"gwcell reveal\"><span class=\"gwnum\">06<\/span><h3>Arming with a mandatory interlock<\/h3><p>Full set, part set and night zone are three states with their own detector allocation, planned to proven VdS logic. The mandatory interlock, using a blocking element and a bolt contact, prevents arming with a cellar window open and prevents anyone walking into an armed area by accident. Operation is by transponder, code, fingerprint or a switch in the hall.<\/p><\/div><div class=\"gwcell reveal\"><span class=\"gwnum\">07<\/span><h3>Alarm paths planned in stages<\/h3><p>An internal sounder to drive an intruder out, an external sounder and strobe so the house can be located, a push message with camera image to the phone, a silent alarm where nobody is meant to be warned. Who is reached in which order, what happens if nobody acknowledges, which path is left if the internet fails? We prepare the technical side for a connection to an alarm receiving centre.<\/p><\/div><div class=\"gwcell reveal\"><span class=\"gwnum\">08<\/span><h3>Ruling out false alarms systematically<\/h3><p>False alarms almost always arise at interfaces: external venetian blinds moving in front of an interior detector, cleaners in an armed area, the position of the sun on the conservatory detector. We link detector zones with presence, shading and scenes, give outside staff their own sub-areas and verify critical activations against the camera image.<\/p><\/div><div class=\"gwcell reveal\"><span class=\"gwnum\">09<\/span><h3>Hazard alarms, not just intrusion<\/h3><p>Smoke alarms, water detectors in the technical room and the utility room, leak protection with a motorised shut-off valve, temperature and frost monitoring in the wine cellar: the same control unit, the same alarm chain, the same app. Water damage in an empty house regularly does more damage than the break-in.<\/p><\/div><div class=\"gwcell reveal\"><span class=\"gwnum\">10<\/span><h3>Linked with lighting and shading<\/h3><p>On an alarm the panic lighting goes to full brightness inside and out, external venetian blinds move to a defined escape position, video entry and cameras supply the picture. In the period building in D\u00fcsseldorf-Oberkassel this runs with Occhio lighting, DoorBird and shading through one shared interface.<\/p><\/div><div class=\"gwcell reveal\"><span class=\"gwnum\">11<\/span><h3>Credible occupancy simulation<\/h3><p>Instead of a rigid time switch we record the real switching patterns and play them back with a random offset and an astronomical clock: light moves through the rooms, the shading runs in the evening, music plays briefly. A house in which the same thing has happened at 19:30 for four days running looks empty.<\/p><\/div><div class=\"gwcell reveal\"><span class=\"gwnum\">12<\/span><h3>Retrofitting in an existing building<\/h3><p>In the 400-year-old manor house in Cologne every core drilling was a discussion with the heritage authority, so wireless it was: measured field strengths, planned battery changes, concealed mounting in reveals and in furniture, alarm and access control together with the Siedle camera. In the detached house in Br\u00fchl the same logic ran over Homematic IP Wired.<\/p><\/div><\/div>\n    <p class=\"gwclose\">Security does not come from more detectors, but from a concept that stays armed in daily life.<\/p>\n  <\/div><\/section>\n<section class=\"spez\"><div class=\"wrap\">\n    <span class=\"eyebrow\">Protected rooms<\/span><h2>Panic room, safe room, walk-in vault.<\/h2><p class=\"splead\">For clients with a heightened need for protection we plan retreat rooms that work when it matters \u2014 technically self-sufficient, securely connected and unremarkable day to day.
