Ajax FireProtect 2 SB (Heat/Smoke/CO) Jeweller

Overview

The Ajax FireProtect 2 SB (Heat/Smoke/CO) Jeweller is a ceiling fire detector that watches for smoke, a dangerous rise in heat and carbon monoxide (CO) from one housing, and reports to your Ajax hub. SB means sealed battery: the two lithium cells are built in and rated for 10 years, after which the whole detector is replaced. It suits homes, offices and rented units where nobody wants to climb up and change ceiling batteries.

Is it right for you?

• It suits a home or office on an Ajax system that wants smoke, heat and CO cover from a single detector per room.
• Choose it when you would rather replace the detector after 10 years than change batteries; the cells cannot be swapped.
• It is indoor only (IP20, 0 to 50 °C), so it is not for garages open to the weather or unheated outbuildings.
• It needs a hub on OS Malevich 2.14.1 or later, or 2.28 or later on Hub (4G); it works with Hub (4G), Hub 2, Hub 2 (4G), Hub 2 Plus, ReX and ReX 2.

Key features

• Double-spectrum optical smoke sensor that ignores water vapour, in a chamber that keeps out dust and insects, so steam from a bathroom or kettle is less likely to set it off.
• Heat sensing to Class A1R: it alarms above 64 °C or when the temperature rises by more than 10 °C within one minute.
• Chemical CO sensor with a 10-year life that alarms on accumulated dose, from more than 50 ppm over 90 minutes to more than 300 ppm within 3 minutes.
• Built-in 85 dB siren (at 3 m), a front button that tests the smoke chamber and silences alarms or fault sounds, and indicator lights for power, faults and fire.
• Interconnected alarms: when one Ajax fire detector triggers, the hub starts the alarm on the others within 20 s.
• Sealed lithium batteries rated for 10 years with the hub’s Battery Life Optimization setting on (the default), or 5 years with it off.
• Jeweller radio to the hub, up to 1,700 m in open space, with communication loss reported within 15 minutes.
• Tamper alarm if it is taken off its SmartBracket panel.

What else you need

An Ajax hub from the compatible list, updated to OS Malevich 2.14.1 or later (2.28 or later for Hub (4G)), and the Ajax app. It can also work without a hub. More FireProtect 2 detectors in other rooms give you interconnected alarms through the hub.

Installation

A ceiling mount on the SmartBracket panel, indoors. An Ajax installer can place it, add it to the hub and check the radio signal. Press the front button after fitting to test the smoke chamber.

Software and licences

Alerts, tests and the Battery Life Optimization setting are managed in the Ajax app.

Before you buy

• The batteries are sealed and cannot be replaced: at the end of their life the detector is replaced as a unit.
• Battery life drops to 5 years if Battery Life Optimization is switched off on the hub.
• Indoor use only, IP20, 0 to 50 °C and up to 80% humidity.
• Check your hub firmware before ordering: OS Malevich 2.14.1 or later, or 2.28 or later on Hub (4G).
