Overview
What it is and how it fits the system.
The Gent S4TB-711-V-VAD-HPR is a black-bodied S4 SELF-TEST Dual Optical Heat Sensor with Voice Sounder and High Power Red VAD from the S-Quad Self-Test (S4T) series. It combines dual optical and heat sensing with an integrated voice sounder and high power red visual alarm device, operating on a 35V-48V loop at 2mA average (4.5mA in Turbo mode) and rated IP21C. The ABS sensor head measures 117mm in diameter by 63mm high and weighs 152g.
Technical overview
The S4TB-711-V-VAD-HPR is a black-bodied S4 SELF-TEST Dual Optical Heat Sensor with Voice Sounder and High Power Red VAD from the S-Quad Self-Test (S4T) series. It combines dual optical and heat sensing with an integrated voice sounder and high power red visual alarm device, operating on a 35V-48V loop at 2mA average (4.5mA in Turbo mode) and rated IP21C.
The ABS sensor head measures 117mm in diameter by 63mm high and weighs 152g. It operates in ambient temperatures from -10°C to +50°C and stores between -20°C to +65°C, with relative humidity tolerance of 95% non-condensing between +5°C and +45°C. The device supports air velocities of 0 to 20 m/s for fire detection and 0 to 1.5 m/s around the unit, with Bluetooth range of 10m and heat self-test effective from 0 to 40°C expected.
Certifications include LPCB approval, CE & UKCA, and compliance with EN54, LPCB, UKCA and CE standards. It requires the Black Base (S4BK-700) and is compatible with recommended accessories such as black IP21 base covers (S4BK-705), semi-flush mounting kit (S4-FLUSH), and remote LED (13449-01).
