Product Overview

Model OOH941 is an advanced, multi-criteria fire

detector that incorporates a redundant, optical /

thermal sensor. Model OOH941 uses a distinctive

forward / backward, light-scattering technology

that provides state-of-the-art, unparalleled fire

detection to the widest range of fire types.

Model OOH941 is programmable as a high-

sensitivity detector, meeting the requirements of

NFPA 76 Standard (for the Fire Protection of

Telecommunications Facilities) as a Very Early

Warning Fire Detector (VEWFD).

The Model OOH941 detector is a flexible, multi-purpose

detector that provides a complete solution to meet

detection needs. This type of detector can be field

programmed for simultaneous and / or independent

functionality, depending upon the exact customer and

application requirements.

For example, the detector can simultaneously utilize the

optical and heat sensors for enhanced fire detection

(multi-criteria), as well as provide together independent

outputs for heat detection. Any combination of the

sensors is possible. The detector is extremely versatile

and meets the following standards:

• UL 268 compliant

• ULC Listed;

FM (

3230, 3210), CSFM

(

7272-0067:0258) Approved

Operation ─ (continued) Field-Device Programmer / Test Unit Model OOH941 is compatible with the Device Program / Test Unit accessory, which is used to program and verify the address of the detector. The technician selects the accessory’s program mode, and enters the desired address. Model 8720 / DPU automatically sets and verifies the address and tests the detector.
PAGE 4
Installation All Model OOH941 detectors use a surface-mounting base (Model DB-11 or Model DB-11E), which mounts on a 4-inch octagonal, square or single-gang electrical box. The base utilizes screw-clamp contacts for electrical connections and self-wiping contacts for increased reliability. The Model DB-11 base can be used with the optional Model LK-11 detector locking kit, which contains 50 detector locks and an installation tool to prevent unauthorized removal of the detector head.
