Notifier FCO-951 Multi-Criteria Fire/CO Detector

The IntelliQuad® PLUS FCO-951/-IV and FCO-951A/-IV advanced multi-criteria fire/CO detector is a plug-in, addressable device that provides both fire and carbon monoxide (CO) detection.

The detector combines four separate sensing elements in one unit to sense multiple components of a fire: smoke, CO, light/flame, and heat. This approach enables enhanced sensitivity to real fire with heightened immunity to nuisance particulates. For CO, the detector’s electrochemical sensing cell creates a separate signal for life safety CO detection.

Multiple sensors and communication can greatly reduce nuisance alarms compared to single sensing methods. Sophisticated algorithms maximize the advantages of the sensor types, creating our best detection strategy and offering heightened immunity to nuisance particulate and enhanced sensitivity to real fire.

• Photoelectric sensors detect airborne particles associated with smoke.
• Thermal sensors detect heat and rate-of-rise (135°F fixed temperature threshold).
• Carbon Monoxide sensors detect this by-product of fire for accurate fire detection.
• Infrared sensors discern environmental light patterns as an additional data point for alarm determination.

This ability to reject certain nuisance alarm triggers, such as theater smoke, supports the use of the IntelliQuad PLUS Series detector in applications where moderate to heavy nuisance conditions exist that might cause single sensing detectors to false alarm.

The IntelliQuad PLUS Series detector meets both UL 268 7th edition and UL 521 listing requirements for fire detection as well as the UL 2075 standard for system-connected life safety carbon monoxide detection. Canadian models meet listing requirements of CAN/ULC S529, CAN/ULC S530 and CAN/ULC S588.

Fire Service Access Elevator (FSAE) applications: Intertek performed an independent evaluation to witness that when used with panels that offer FSAE monitoring, the FCO-951/FCO-951-IV can be used to transmit alarms and also to continuously monitor temperature between +80°F and +135°F, meeting requirements of NFPA 72 Section 21.5 and Section A21.5.

Released through the incomplete burning of various fuels, CO is a colorless, odorless and deadly gas that is virtually impossible to detect with the human senses. Because the potential exists for dangerous levels of CO to accumulate in almost any building, legislation mandating the use of CO detection in commercial spaces continues to grow.
B200S series intelligent sounder bases (B200SCOA series in Canada) are recommended for use with FCO-951 Series IntelliQuad PLUS.

These bases can generate either a Temp 3 pattern for fire or a Temp 4 pattern for CO alarm indication. The B200S/B200SCOA series bases recognize the System Sensor synchronization protocol, for use as a component of the general evacuation signal — along with other System Sensor horns, horn strobes, and chimes — when connected
to a power supply or Fire Alarm Control Panel (FACP) output capable
of generating the System Sensor synchronization pulses.
