Gira Alarm and security systems

In modern buildings — commercial offices, residential complexes, smart‑homes or system‑integrated properties — the security and alarm infrastructure is no longer an after‑thought. The Gira alarm and security systems range provides motion detectors, presence sensors, alarm sirens, intrusion‑protection modules, security control units and the accessories needed to tie them into building management. From my field experience: specifying the right product family up‑front saves integration issues later, avoids false alarms, and aligns the system with wiring, sensor zones and serviceability.

Gira Motion Detectors — Outdoor & Indoor Movement Detection

When the task is to monitor movement and trigger lighting, alarms or automation, you’ll look at Gira motion detectors. For instance, Gira’s “Motion and presence detectors” page describes their detectors that switch lights automatically based on movement or brightness.
In practice: you’ll check detection angle (e.g., 120° or 240° for outdoor models), mounting height, IP‑rating (for outdoor or wet zones), compatibility with your bus or wiring system (KNX, System 3000, etc.). A detector that’s over‑sensitised or badly placed leads to nuisance trips, especially in stairwells or glazed zones.

Gira Presence Sensors — Occupancy, Light & Alarm Integration

For zones where presence rather than mere motion matters (meeting rooms, corridors, control rooms) you’ll deploy Gira presence sensors. These devices remain active while people are present, and can tie into lighting, HVAC or security logic. Gira’s System 3000 series for presence detection is cited in online‑data. 
On installation: you’ll validate coverage area, minimum detection speed, ambient brightness cut‑offs, and whether the sensor can integrate an alarm‑output or report absence. Specifying the correct presence sensor ensures you reduce false “no‑occupancy” alarms and keep lighting/ security systems aligned.

Gira Alarm Sirens & Security Control Units — Audio/Visual Alerting and System Logic

When an intrusion or security event must be signalled, you’ll use Gira alarm sirens and Gira security control units — the hub that receives zone‑faults, triggers alarms, handles access control or remote monitoring. For example, Gira’s “Alarm Connect G1 interface” is shown as a security‑system control module.
From a systems viewpoint: you’ll check the siren’s decibel rating, mounting location (internal vs external), cable entry/sealing, back‑up power or battery behaviour, control‑unit compatibility (firm‑ware, zones, remote access). Choosing the right control unit from the start ensures the wiring, zones and installer‑logic match your wider building system.

Gira Intrusion Protection & System Accessories — Complete Security Infrastructure

Beyond the active devices, the category of Gira intrusion protection and Gira system accessories encompasses wiring modules, zone interface boards, tamper sensors, remote keypads, and mounting kits—all the “behind the scenes” parts that make the system reliable.
In procurement you’ll check: the number of input zones, compatibility with existing bus or BMS, spare interface modules, mounting and cable accessories. From installation experience: missing system accessories cause the installer to improvise and that often leads to warranty or maintenance issues.

Procurement Insights for B2B Buyers

When purchasing Gira alarm and security systems in volume (multi‑unit buildings, retrofit programmes, smart‑home roll‑outs), the key evaluation points are:

• Detection coverage vs building geometry: motion vs presence vs zone‑type sensor.
• Environmental rating: IP/IK for outdoor or exposed zones, tamper detection, surge protection.
• System integration: Can sensors and alarms link to your BMS, access‑control or automation bus? Are firmware, remote management supported?
• Spare modules & accessories: ensure the full range (sensors, sirens, control units, mounting kits) is available from the same brand.
• Stock and logistics: security systems are often commissioned late in the schedule—delayed delivery of sensors or control units holds up hand‑over.
• Brand‑ecosystem: using Gira for the entire security chain (motion, presence, siren, control, accessories) simplifies spares, training and documentation.
  From real project work: I’ve seen hand‑over delayed because the siren’s mounting bracket or wiring accessory was missing—even though devices were onsite. Specifying the full kit in one go avoids this.
