- Supply voltage:9 6 V DC (typical 12 V) compatible with standard wired control panels and power supplies used in security and fire systems.
- Current consumption:Approximately 15 mA typical low standby draw reduces load on auxiliary power supplies and batteries.
- Wiring:4‑wire (power + signalling) provides reliable, supervised connections and straightforward integration with panel inputs.
- Alarm relay rating & resistance:<24 V DC, 50 mA; relay resistance approximately 18 Ω suitable for signalling conventional control panel inputs or relay-expander modules.
- Latch input:12 V for latching mode or 0 V for auto-reset flexible behaviour to match site requirements (manual reset vs automatic recovery).
- Packed weight & storage:Packed weight roughly 200 g and storage temperature range 6C to +80C robust for common warehouse and transport conditions.
- Certification:EN54-7 (optical smoke detector standard) third-party recognition for installations in regions that require or prefer EN-conformant devices.
Benefits that follow from these specifications include earlier detection across a wider range of fire types (smouldering and flaming), reduced false alarms due to algorithmic drift compensation, flexible installation options with latch/auto-reset selection, and easy verification via the built-in test button during commissioning and maintenance.
How the multisensor approach improves detection
The AGB-0001 uses an optical chamber to detect smoke particles combined with a thermal sensing element. The optical sensor responds well to smoke from smouldering fires and slow-developing combustion, while the thermal sensor can respond faster to rapid temperature rise associated with open flaming fires. Local microprocessor algorithms compare and weigh inputs from both sensors, and apply drift compensation to prevent gradual contamination of the optical chamber from causing nuisance alarms. The result is a detector that offers faster, more reliable detection across diverse fire profiles and in challenging environments where single-sensor devices may either alarm late or trigger falsely.
Use cases and scenarios where the AGB-0001 excels
The Texecom Exodus multisensor detector is suitable for a broad range of installations, especially where reliable detection and low nuisance alarm rates are priorities:
- Commercial offices and retail spaces:Busy environments with dust, HVAC movement or kitchen fume pathways benefit from the multisensor approach to avoid unnecessary evacuations while maintaining safety.
- Residential blocks and communal areas:EN54 certification and wired integration make it a fit for apartment corridors, common rooms and concierge areas protected by conventional wired fire systems.
- Light industrial or storage areas:Facilities where welding, light dust or temperature fluctuations occur can use the thermal element and algorithmic filtering to reduce false alarms while still detecting genuine events.
- Security-integrated installations:Where fire detection is incorporated into broader security panels, the detectors 4‑wire interface and NC relay provide straightforward connection and supervised signalling.
- Refurbishments and discreet installations:The low-profile ceiling mount makes it suitable for retrofit projects where maintaining aesthetics is important.
Comparisons with similar products in the market
When choosing a detector, specifiers typically weigh multisensor detectors like the Texecom AGB-0001 against three main alternatives: optical (photoelectric) smoke detectors, heat-only detectors, and other multisensor models from competing manufacturers. Key comparative points follow.
Vs optical-only detectors:Optical detectors are excellent at detecting smoky, smouldering fires but are more vulnerable to nuisance alarms caused by dust, insects or steam. The AGB-0001s additional thermal sensor and processing algorithms help discriminate true alarm conditions from common environmental triggers, reducing downtime and maintenance calls.
Vs heat-only detectors:Heat detectors respond to a rapid rise in temperature or a fixed high temperature and are less likely to false alarm from dust or steam, but they detect smouldering fires late. The multisensor approach improves early detection for smouldering fires while retaining robust performance against fast-flaming fires.
Vs other multisensor models:Many major manufacturers offer multisensor detectors with similar aims: combining smoke and heat elements and applying signal processing. The AGB-0001 distinguishes itself through a compact profile, low current consumption (about 15 mA), and EN54-7 certification for optical detection. When comparing specific models, installers should consider certification (EN vs local standards), power consumption, relay characteristics, wiring topology and local support/documentation. The AGB-0001s latch input (12 V latching vs 0 V auto-reset) and built-in test button are practical features that ease commissioning and maintenance compared to some basic detectors that lack such flexibility.
Wired vs wireless choices:The AGB-0001 is a wired 4‑wire detector, which is often preferred for fixed commercial installations where supervised circuits and direct panel signalling are required. Wireless multisensor detectors offer installation flexibility but may introduce considerations around battery life, RF reliability and compliance in large commercial systems.
Choose the Texecom AGB-0001 when you need EN54-7-compliant optical detection, improved false alarm immunity through multisensor logic, and a wired, low-profile device that straightforwardly integrates with conventional control panels. For projects where wireless or addressable detection schemes are mandated, consider those architectures and compare feature parity with the AGB-0001.
Customer feedback and installer impressions
Direct online reviews for specific detector models can be limited because most units are purchased through trade channels and installed by professionals. Where industry feedback is available and where installers have reported on their experience with the AGB-0001, common themes include:
- Appreciation for reduced nuisance alarms in mixed-use environments thanks to multisensor processing.
- Positive comments about the compact, unobtrusive design and easy ceiling mounting during retrofit projects.
- Recognition of the EN54-7 certification as a valuable feature for specifiers and compliance-minded projects.
- Practical benefits from the latch/auto-reset option and the built-in alarm-test button for commissioning and site testing.
Because customer reviews are typically indirect (installer and system integrator feedback rather than retail consumer reviews), prospective buyers should consult local installers or system integrators for site-specific performance anecdotes and reference installations.
