FireProtect 2 (Heat/CO) is a wireless fire detector that detects temperature increases. It is designed for indoor installation and operates as part of an Ajax system. The detector is equipped with a siren for audible notification of alarms and events.

FireProtect 2 is available in two modifications:

• with non-replaceable batteries (has SB in the name), which last 10 years;
• with replaceable batteries (has RB in the name), which last up to 7 years.

The detector operates as part of an Ajax system, communicating with the hub via the secure Jeweller radio protocol. The communication range with the hub in the absence of obstacles is up to 1700 meters.

The detector is always active, so it responds to fire 24/7, regardless of the system's security mode.

FireProtect 2 is tamper-protected. It monitors the removal of the detector from the SmartBracket mounting panel.

Ajax automation devices can react to a FireProtect 2 alarm and perform user-defined actions using automation scenarios.

Two built-in A1 class thermistors are responsible for detecting a sharp rise and exceeding the temperature threshold in FireProtect 2. They signal an alarm if a rapid temperature increase or a static temperature within the range of +54°C to +65°C is detected.

FireProtect 2 will report an exceedance of the permissible temperature threshold as soon as its value exceeds +64°C. The detector will report a sharp temperature increase if the reading increases by 10°C within one minute. If the temperature reading sharply increases by 20°C or more, the detector immediately signals.

The Test/Mute button allows you to:

• start a detector performance test;
• mute a detector alarm or a synchronous alarm of all fire detectors in the system for 10 minutes;
• mute audible and LED indication for 12 hours.

All FireProtect 2 series fire detectors support the synchronous alarm function. This function activates the built-in sirens of all fire detectors in the system as soon as at least one fire detector registers an alarm.

The Ajax system can transmit alarms and events to the PRO Desktop monitoring application, as well as to a central monitoring station (CMS) in SurGard (Contact ID), SIA DC-09 (ADM-CID), ADEMCO 685, and other protocols.

Brief summary:

FireProtect 2 (Heat/CO) is a reliable wireless fire detector that will help protect your property from fire. It is easy to install and use, and has a wide range of features, including synchronous alarm and support for automation devices.

| Brand | Ajax |

| Model | FireProtect 2 SB (Heat/CO) |

| Detector type | Combined detector |

| Sensor type | Wireless |

| Sensing elements | Temperature sensor, CO (carbon monoxide) sensor |

| Compatibility | Hub Plus, Hub 2 (2G), Hub 2 (4G), Hub 2 Plus, Hub Hybrid (2G), Hub Hybrid (4G), ReX, ReX 2 |

| Detected gas | CO (carbon monoxide) |

| Hazardous temperature detection | Sensing element meets the requirements for A1 class temperature sensors. Complies with EN 54-5 and BS 5446-2 standards. Triggers at temperatures above 64°C. Triggers at a rapid temperature increase of more than 10°C in 1 minute (or faster). |

| Sabotage protection | Tamper against opening. Reports attempts to detach the detector from the surface or remove it from the mounting panel. |

| Communication loss protection | Device authentication. Detection of communication loss within 15 minutes. The time to detect communication loss depends on the settings for the number of unsent data packets (specified in Jeweller or Jeweller/Fibra settings). The polling period is fixed - 300 seconds. |

| CO (carbon monoxide) detection | Sensitive chemical CO sensor. Triggers when the accumulated CO dose exceeds 50 ppm (0.005%) - in no more than 90 minutes. More than 100 ppm (0.01%) - in no more than 40 minutes. More than 300 ppm (0.03%) - in no more than 3 minutes. Potentially dangerous CO concentration - 400 ppm (0.04%) for 3 hours. The sensor stops reporting dangerous CO levels when the concentration drops to 50 ppm (0.005%) within one minute. Sensor lifespan - 10 years. After 10 years of service, the sensor should be replaced with a new one. |

| Communication | Jeweller communication technology. Proprietary wireless technology for transmitting alarm and event signals. Features: - Two-way communication. - Protection against device spoofing. - Block encryption with a floating key. - Instant notifications. - Remote configuration via Ajax. |

| Radio frequency ranges | 866.0 – 866.5 MHz |

| Maximum effective radiated power (ERP) | Up to 20 mW. Automatic power adjustment to reduce energy consumption and radio interference. GFSK radio signal modulation. Radio communication range up to 1700 meters between the detector and the hub (or radio signal repeater) in the absence of obstacles. Radio communication encryption. All stored and transmitted data are protected by block encryption with a floating key. Radio frequency hopping to prevent radio interference and jamming. |

| Connection method to control panel | Wireless |

| Wireless signal transmission range | 1700 meters |

| Additional features | Built-in siren. Volume 85 dB at 3 meters. Audible alarm notification. Active until the cause of the trigger is eliminated or until the user disables the notification. Synchronous fire detector alarms. Fire detectors in the system activate built-in sirens as soon as at least one detector registers an alarm. Synchronous alarm is activated within one "hub - detector" polling interval, but no more than 20 seconds. LED indication: - Green - power indication. The LED indicator on the device body flashes once every 56 seconds. Indication complies with EN 50291 standard requirements. - Yellow - fault indication. The LED indicator on the device body flashes when faults are detected, such as low batteries, smoke chamber contamination, or end of service life. - Red - fire alarm indication. The LED indicator on the device body flashes when the detector detects a fire alarm. Button on the front panel of the detector: In normal mode, pressing it starts a smoke chamber test. During an alarm or fault, pressing it mutes the detector's audible notification. |
