Description
The Gent S4-711-V-VAD-HPW is an S-Quad dual optical and heat sensor with a voice sounder and a white High Power VAD for Vigilon Plus, Compact Plus and Nano. At High, its light covers C-6-16; on Nano it runs at Low with C-3-10.8 coverage. It takes power from the loop and has a built-in short-circuit isolator. Stored voice messages give spoken warnings alongside the light. Use the S4-701 base and IP seal plate for IP21C. By default, the light flashes once every two seconds. Across the S-Quad range, the head is 117 mm in diameter and 49.6 mm high. A red LED gives a fire indication at the device.
S4-711-V-VAD-HPW combines forward and backward optical smoke sensing with heat. The panel selects the detection state. States 2, 6, 11 and 12 do not meet EN 54-7; the selected state must match the required smoke and heat response.
Read the full technical description
S4-711-V-VAD-HPW combines forward and backward optical smoke sensing with heat. The panel selects the detection state. States 2, 6, 11 and 12 do not meet EN 54-7; the selected state must match the required smoke and heat response.
Four English speech messages cover emergency evacuation, an incident alert, a system test and fire evacuation, with a bell tone available as well. Audio storage is up to 20 seconds, with additional local attention tones. Speech follows an attention tone, and pauses before and after the message can be programmed. Fault monitoring checks the speech circuit without playing a test sound.
The white High Power VAD offers High, Medium and Low settings. Ceiling coverage is C-6-16, C-3-14 and C-3-10.8 respectively. Medium also supports O-5-14 and Low supports O-4-10.8. On Nano the light is fixed at Low, giving C-3-10.8 coverage. Use the two-second flash interval for EN 54-23 operation.
Supplied with one sensor head and one blue protective dust cover. The mounting base and IP21 mounting plate are not included. Fit the S4-701 base with its IP seal plate to achieve IP21C. S-Quad VAD installations require an IP21 mounting plate for EN 54-23 operation. The voice sounder and visual alarm synchronise across all loops of the same panel. Synchronisation does not extend across a network of panels.
For Vigilon Plus and Compact Plus VAD coverage, use MCC/MCB software v4.52 or later and LPC software v4.48 or later. Use Vigilon Commissioning Tool v1.32 or later for device setting changes. Nano configuration uses Nano Commissioning Tool v3.0 or later. Verify the system design with the Gent Battery Standby and Loop Load calculator.

FAQs
What visual alarm coverage does S4-711-V-VAD-HPW provide?
At High, the S4-711-V-VAD-HPW gives C-6-16 ceiling coverage, equal to 1206.3 m³. Medium gives C-3-14 and Low gives C-3-10.8. The open categories are O-5-14 at Medium and O-4-10.8 at Low. In a C rating, the two numbers give the maximum ceiling height and coverage diameter, both in metres; the covered space is cylindrical. Use a two-second flash interval and the S4-701 base with its IP seal plate. Coverage changes with the selected power setting.
Which voice messages are available on S4-711-V-VAD-HPW?
The S4-711-V-VAD-HPW has four factory English speech messages and a bell tone. The spoken choices cover emergency evacuation, an incident alert asking occupants to wait, a test requiring no action, and fire evacuation. An attention tone precedes each speech message. Audio storage is up to 20 seconds, with additional local attention tones. The pauses before and after speech can be programmed, and factory speech can be replaced with custom messages. Silent monitoring checks the speech function for failure.
How does S4-711-V-VAD-HPW operate on Nano?
The S4-711-V-VAD-HPW works on a Nano loop, where its VAD is fixed at Low. Its ceiling coverage on Nano is C-3-10.8 and its open coverage is O-4-10.8. The High and Medium visual alarm settings are therefore unavailable on Nano. Its sensing and voice functions remain part of the device. Configure the Nano system with Nano Commissioning Tool v3.0 or later. Use the S4-701 base and IP seal plate, and keep the visual alarm flash interval at two seconds.
Which panel software and tools are needed for S4-711-V-VAD-HPW?
For S4-711-V-VAD-HPW on Vigilon Plus and Compact Plus, EN 54-23 coverage needs MCC/MCB software v4.52 or later and LPC software v4.48 or later. Use Vigilon Commissioning Tool v1.32 or later for setting changes. Nano configuration uses Nano Commissioning Tool v3.0 or later, and its VAD setting is fixed at Low. Use the two-second flash interval for EN 54-23 operation. Verify the complete system design with the Gent Battery Standby and Loop Load calculator.
How are S4-711-V-VAD-HPW alarm outputs set up and synchronised?
The S4-711-V-VAD-HPW voice sounder and VAD outputs synchronise with compatible devices across all loops belonging to the same panel. Synchronisation does not extend across a network of panels. The white VAD uses a two-second flash interval for EN 54-23 operation. The sounder provides speech preceded by an attention tone, as well as tone signals. On Nano, this VAD operates at Low with C-3-10.8 ceiling coverage. Fit the S4-701 base and IP seal plate for IP21C.
