Introduction to the Texecom Exodus RR 4‑Wire Rate‑of‑Rise Heat Detector (AGB-0002)
Texecom Exodus RR (AGB-0002)is a wired, 4‑wire rate‑of‑rise heat detector designed for reliable connection to security and fire alarm control panels. Built around a microprocessor‑based thermal algorithm with electronic drift compensation, this detector triggers on rapid temperature rises or when a fixed threshold above 58C is exceeded. EN54 approved and carrying the BSI Kitemark as part of the Exodus EN54 series, the unit is aimed at installers and end users who need a fast, dependable thermal detection solution for environments where smoke detectors may be unsuitable.

Detailed Specifications and Benefits
Knowing the specifications helps you match the detector to the application. The Exodus RR AGB-0002 operates from a nominal 12 V DC supply (range 916 V DC) and draws around 15 mA in normal operation, making it suitable for typical powered detection loops. The 4‑wire design separates power and signalling, allowing the detector to provide a monitored relay output back to a control panel while maintaining its own power feed.
The detection approach combines rate‑of‑rise (RoR) sensing with a fixed temperature threshold of greater than 58C. Rate‑of‑rise detection identifies situations where temperature increases rapidly — a hallmark of developing fires — while the fixed threshold ensures detection of slower, smouldering but high‑temperature events. A microprocessor‑based digital thermal algorithm and electronic drift compensation minimize nuisance alarms caused by slow environmental changes or sensor ageing. The result is a detector tuned for sensitivity to genuine fire conditions while maintaining immunity to everyday thermal fluctuations.
Mechanically, the detector is compact and installer‑friendly. A ceiling connector base simplifies mounting and wiring, and a built‑in test/alarm simulation button enables on‑site functionality checks without removing the cover. The internal alarm relay is normally closed and opens on alarm (spec: <24 V DC, 50 mA with 18 Ω), useful for straightforward integration with many security and fire panels that monitor the detector relay state. Installers can also configure the latch input for either latched alarms (12 V) or auto‑reset operation (0 V), giving flexibility to match the system behaviour required by site procedures.
Environmentally, the detector is designed to operate between 10C and +55C (storage 20C to +80C), covering most indoor applications. For compliance and peace of mind, the Exodus RR is EN54 approved with BSI Kitemark certification when used as part of the Exodus EN54 range. Texecom offers a manufacturer‑stated 5‑year replacement warranty, which underscores the brands confidence in product reliability.
Use Cases and Scenarios Where the Detector Excels
Rate‑of‑rise heat detectors are particularly valuable in locations where conventional smoke detection may be unsuitable due to dust, steam, fumes, or other particulates that can cause false alarms. Common applications for the Texecom Exodus RR include:
- Industrial workshops and manufacturing areas where dust, oil mist or airborne particles preclude reliable smoke detection.
- Kitchens and cooking areas in commercial premises where smoke and steam are frequent and could trigger smoke detectors falsely.
- Boiler rooms and plant rooms where the environment is prone to temperature swings and where a fast thermal response is advantageous.
- Parking garages and enclosed store rooms where smoke stratification or dust makes smoke sensing less predictable.
- Heritage buildings or specialised installations where minimal false alarms are critical and a robust thermal approach is preferable.
In each of these situations, the Exodus RRs fast response to rapid temperature increases, combined with a high fixed threshold, significantly reduces the chance of nuisance activations while providing a timely alarm in genuine fire events. The ability to set latching or auto‑reset behaviour also helps tailor response protocols for different premises: for instance, latching in high‑security locations (so alarms are retained until manually cleared) and auto‑reset in transient environments.
Comparisons with Similar Products on the Market
When comparing the Exodus RR to other wired heat detectors, there are several factors to weigh: detection modes (rate‑of‑rise vs fixed temperature), approvals, power requirements, integration options, and cost. Many basic heat detectors rely solely on fixed temperature thresholds (e.g., 58C or 65C). These are simple and reliable but can be slower to respond to rapidly developing fires. Conversely, RoR detectors like the Exodus RR add a layer of responsiveness for rapid temperature escalations, which can be critical in some fire scenarios.
Compared with combined smoke/heat multi‑sensors, the Exodus RR is specialised for thermal detection and therefore excels in environments where smoke sensing is problematic. Multi‑sensors are versatile but may be more susceptible to contamination in harsh environments or require more maintenance. In terms of approvals, the EN54 certification and BSI Kitemark position the Exodus RR strongly for projects requiring certified components.
Finally, on price and value: with a suggested retail price around A336.70 (manufacturer cost price noted at A330.82), the Exodus RR sits as a competitively priced, EN54‑approved thermal detector. For installers and system designers seeking certified performance, the combination of RoR processing, drift compensation, and a flexible relay/latch interface delivers strong value compared with basic heat detectors lacking these features.
Customer Feedback and Installer Comments
Direct public customer reviews for specialist detectors can be limited, but feedback from installers and system integrators typically highlights a few recurring strengths of RoR detectors in this class. Common, anonymised remarks reported by professionals include:
- Reliable operation in harsh environments:Installers appreciate that the Exodus RR continues to operate accurately in dusty or steamy conditions where smoke detectors would need frequent cleaning or replacement.
- Quick, predictable responses:The rate‑of‑rise function is often cited as providing faster alarm confirmation in fast‑developing thermal events without increasing false alarm rates.
- Ease of installation and maintenance:Features such as the ceiling connector base and the test/alarm button make commissioning and routine checks straightforward, saving time on site.
These anecdotal points line up with the products technical design: microprocessor processing and drift compensation are intended to lower nuisance alarms, while the mechanical design helps installers keep labour time down.
Conclusion: Why the Texecom Exodus RR Is a Strong Choice
For installations requiring robust, fast, and reliable thermal detection, the Texecom Exodus RR 4‑Wire Rate‑of‑Rise Heat Detector (AGB-0002) is a compelling option. It combines rate‑of‑rise and fixed threshold detection, microprocessor‑based processing with drift compensation, flexible relay and latch options, and recognised EN54/BSI approvals. These characteristics make it well suited to industrial, commercial kitchen, plant room, and other challenging environments where smoke detectors are impractical or prone to false alarms.
