The Kidde KI-OSD is an intelligent addressable optical smoke detector from the Kidde Intelligent Optica Series. Specifically, it uses multi-criteria optical sensing technology to reduce nuisance alarms in dusty, steamy, or otherwise variable environments. As a result, it suits commercial spaces that require both early warning and low false-alarm rates.
In addition, the KI-OSD communicates on a standard two-wire SLC loop. Therefore, it draws operating power and reports its status over the same pair of conductors.
How the Kidde KI-OSD Detects Smoke
First, the sensor uses two optical wavelengths instead of a single one. Then, it analyzes light scatter from multiple detection angles. As a result, the algorithm can tell common nuisance particulates (dust, steam, cooking aerosols) apart from genuine smoke.
Furthermore, the detector reports individually to the panel. Therefore, the system identifies the exact device in alarm, not just the zone.
Important Panel Compatibility Note
The KI-OSD operates ONLY with control panels that use a Kidde Intelligent Loop controller. Therefore, this detector is not interchangeable with detectors from other manufacturers or other Kidde product lines. Specifically, before ordering, confirm your panel uses a Kidde Intelligent Loop card.
Specifications
- Function: Intelligent addressable multi-criteria optical smoke detector
- Series: Kidde Intelligent Optica Series
- Sensing technology: Dual optical wavelengths, multiple detection angles
- Communication: Kidde Intelligent two-wire SLC loop
- Standards: UL 268 7th Edition; CAN/ULC-S529
- Panel requirement: Kidde Intelligent Loop controller
Mounting Box Compatibility
The KI-OSD mounts to standard North American electrical boxes:
- 1-gang electrical box
- 3-1/2″ octagonal box
- 4″ octagonal box
- 4″ square box, 1-1/2″ (38 mm) deep
In addition, European installations can use BESA boxes or 1-gang boxes with 60.3 mm fixing centers. However, always verify the depth of the box against the specific Kidde base being installed.
Typical Applications
- Office buildings and conference centers
- Schools and university facilities
- Healthcare environments with nuisance-prone spaces
- Hotels and multi-occupancy residential buildings
- Retail and commercial environments with broad daily activity
Related Variants
Specifically, the KIR-OSD is the same optical sensing technology in an isolator-base form. Therefore, where the system design requires loop isolation, consider the KIR-OSD instead of the KI-OSD.
