Product Overview
Model OOHC941 is an advanced, multi-criteria fire / CO detector that incorporates a redundant, optical / thermal sensor with a carbon monoxide (CO) sensor. Model OOHC941 uses a unique forward / backward light-scattering technology providing state-of-the-art,
unparalleled fire detection to the widest range of fire types.
For instance, the detector can utilize the optical, heat and CO sensors together for enhanced fire detection (multi- criteria), as well as simultaneously provide independent
outputs for CO gas life-safety and heat detection. Any combination of the sensors is possible. The detector is
extremely versatile and meets the following standards:

Model OOHC941 which provides extremely accurate and reliable fire detection with built-in redundancy utilizes advanced, multi-criteria detection technology known as ASA (Advanced Signal Analysis) that allows the detector to distinguish non-threatening deceptive phenomena.
For instance, the signals from the detector’s sensors are monitored and processed via the ASA-patented algorithm technology, which combines the signals into a neural network to create an intelligent, multi-criteria detector.
The encompassing result is a detector that provides enhanced detection to a wide range of products of combustion while offering unsurpassed rejection to nuisance-alarm sources, such as: dust, steam, aerosols and other deceptive phenomena that could cause false alarms.
Since the multi-criteria, CO detector is a (2) two-wire, addressable device, it is then able to function as a multi- purpose detector satisfying fire, heat and carbon monoxide (CO) gas detection in a singular, aesthetically pleasing package. Further, Model OOHC941 serves as an extremely cost-effective, viable solution that saves product, installation and maintenance costs (compared to other multiple-detector alternatives). Each detector fits into one (1) wall-or-ceiling footprint, and only occupies one (1) address on the signal-line circuit (SLC).
A patented forward-and-backward, light-scattering technology which is able to distinguish both small and large products of combustion operates at the core of each Model OOHC941 detector.
Additionally, each Model OOHC941 provides an environmental-friendly solution to ionization detectors, eliminating the need for a radioactive source and eventual disposal requirements. Thus, each detector is capable of detecting both smoldering and flaming fire all in ecologically efficient manner and is a valid, RoHS- compliant (Restriction of Hazardous Substances) detection alternative to ionization detectors.
Two (2) thermal sensors and an electromechanical CO sensor are also included, making each Model OOHC941 detector a robust, reliable device suitable for the most challenging applications. ModelOOHC941alsoworksasacarbon monoxide (CO) life-safety gas detector, compliant with NFPA 720 and UL 2075.

6. CO sensor
The high-quality, optical-electronic measuring chamber for each Model OOHC941 houses the following components:
Two (2) optical transmitters One (1) optical receiver
Two (2) thermal sensors One (1) CO sensor
The transmitters illuminate the smoke particles from different angles: asabackwardscatterer. Thescatteredlightthenhitsthe receiver (photodiode) and generates a measurable electric signal. facilitates optimum detection, as well as differentiates between light-and-dark particles / particle size.
This type of detection creates standardized, responsive behavior and optimizes the differentiation between wanted signalsanddeceptivephenomena. Inaddition,theheat sensors make it possible to detect fires without smoke generation.
The CO sensor enables faster detection of fires with incomplete combustion, as well as fires with the development of high levels of CO. The combination of optical, thermal and CO sensor signals optimizes detection reliability.
Field-Device Programmer / Test Unit
Model OOHC941 is compatible with the Device Program / Test Unit accessory, which is used to program and verify the address ofthedetector. mode, and enters the desired address. Model 8720 / DPU automatically sets and verifies the address and tests the detector.
Model 8720 / DPU eliminates the need for cumbersome, unreliable mechanical programming methods such as dials or switches and reduces installation and service costs by electronically programming and testing the detector prior to installation.
Model 8720 / DPU operates on AC power or rechargeable batteries, providing flexibility and convenience in programmer and testing equipment from practically any location.
When in ‘test’ mode, Model 8720 / DPU will perform a series of diagnostic tests without altering the address or other stored data, allowing technicians to determine if the detector is operating properly.
Field-selectable application profiles
Model OOHC941 provides 26 user-friendly, field-selectable application profiles, indentified with universally known names (e.g. Hotel, Telco, Office, Parking Garage, Dormitory, and DataCenteretc.) Refertoinstallationmanual: P/N A6V10324657 for a complete list and description of application profiles.
Due to generic-name classification, no cross-reference tables are required as the application name resides in the panel’s configuration tool. This user-friendly feature along with the algorithms provided by ASAtechnology provides a reliable, field-configurable detector suitable for an array of applications.
Field-selectable temperature settings
Model OOHC941 provides five (5) field-selectable temperature thresholds,rangingfrom135°F to175°F(57°Cto79°C),with fixedandrate-of-riseoptions. Theserangesprovidemaximum flexibility to program and easily adjust the temperature settings that suit multiple application needs within a building or changing environmental conditions.
