Overview
What it is and how it fits the system.
The Gent S4-720-V-VAD-HPR is an S4-family loop-powered addressable heat sensor combined with a voice sounder and a high-performance red Visual Alarm Device. It integrates heat detection, audible voice alarm and high-performance red visual signalling in a single unit. With a load factor of 17.5, up to 55 are supported per loop.
Technical overview
S4-720-V-VAD-HPR is a Gent by Honeywell addressable heat detector from the S4 Detectors range, integrating a voice sounder and high-performance red Visual Alarm Device in a single loop-powered unit. It combines heat detection, audible voice alarm, and visual signalling with a load factor of 17.5, allowing up to 55 devices per loop.
The device operates within a temperature range of -10°C to +50°C and holds EN54 certification covering Smoke Part 7, Heat Part 5, VAD Part 23, Sounder & Voice Sounder Part 3, Isolator Part 17, and Input/Output Part 18. Its dimensions are 49.6 mm diameter (63.8 mm with base) and 117 mm height (140 mm with base and IP21 plate), with an approximate weight of 0.11 kg (0.17 kg with base).
Compatibility requires the IP21 base (S4-701) for EN54-23 compliance, while the common S-Quad base (S4-700) and IP21 base covers (S4-705) are also specified for proper installation and certification. Wiring details are referenced in the installation manual.
