Foam turret
An activatable turret for extinguishing fires. The turret stands idle until someone approaches and activates it, after which it will automatically spray large amounts of firefoam on any flames in sight.

Foam turrets are security turrets that fire firefoam at nearby fires when activated by a pawn.
Acquisition[edit]
Foam turrets can be constructed once the Foam turret research project has been completed. Each requires 30 Stuff (Metallic, 300 for SVMs), 70 Steel, 3 Components, 140 Chemfuel, 1,800 ticks (30 secs) of work modified by the construction speed of the builder and the work to build factor and offset of the material, and a construction skill of 5.
Summary[edit]
The foam turret is used to rapidly extinguish fires within its range. Foam turrets must be manually activated, by either selecting a pawn, right-clicking the turret, and selecting "Activate," or by using the turret's "Order Activation" gizmo, which allows selection of a pawn to come and activate the turret. Activation does not require the pawn to have any work type enabled and can be done by pawns who are otherwise incapable of firefighting, such as pyromaniacs. Drafted pawns will perform the task and remain drafted, even when selected via the gizmo.
When activated, it will consume one of its charges and briefly spray fires within line of sight and range with firefoam for 82 ticks (1.37 secs), covering the ground in firefoam filth. After activation, it will enter a 3,600 ticks (1 min) cooldown before it can be activated again. It cannot be activated unless there is fire present within range and line of sight. It has a maximum range of 20 tiles.
Pawns on fire are considered fire by the foam turret, and can be activated to extinguish them. However, there are no guarantees the turret will extinguish the pawn. Pawns hit by the foam attack will be covered in foam, extinguishing them, however it is possible for an ignited pawn to evade a foam turret's attack while it runs around.
The foam turret has 10 charges, all filled on construction. Chemfuel must be fed to it in order to refill expended charges. The turret can be rearmed at charge value below 10 and at any time, including when the turret is repressurizing. Rearming requires 7.2 chemfuel required for each charge to be rearmed, rounded up with any excess wasted. That is, rearming one charge would required 8 chemfuel but two charges would require 15 chemfuel. 72 chemfuel is required to fill the turret from empty to full. The turret is rearmed by haulers or lifters.
Unlike other turrets, they will not explode if damaged below 20% health. While they do 'explode' when destroyed, it is instant, damageless, and will cover pawns within a 4-tile radius in foam. This explosion does not produce firefoam filth, but it will extinguish fires.
In addition, raiders do not consider foam turrets priority targets, and will ignore them in favor of attacking other turrets or pawns. However, they will target them, similar to other pieces of furniture, if there are no active threats nearby.
Analysis[edit]
Foam turrets are best used for cheap, targeted firefighting in situations where area coverage or component availability is a concern. They have a range of 20 tiles, significantly larger than their firefighting brother, the firefoam popper, which only has a range of 10 tiles. Additionally, firefoam turrets only consume chemfuel on use. This is in contrast to a firefoam poppers, which require steel and components to build or rebuild, making them much more resource intensive in situations where either are in short supply, or where fires are common.
However, there are a few trade offs. The turret requires 80 W of power to use, limiting its use to home firefighting or strict defensive combat. Additionally, their time spent dousing fires per activation is rather low. Combined with a slow turret rotation speed, a foam turret may only realistically douse a quarter of it's circumference in foam (see image right). Compared to a popper, which will douse every tile within range and line of sight with foam. A foam turret cannot be relied upon if fires are particularity massive or encompass a large portion of the turret's circumference. Additionally, foam turrets have a cooldown of one in-game hour (3,600 ticks (1 min)), meaning that more than one turret may be required if fires are common, spread out, or during combat where a lot of fire is produced (such as when fighting impids).
Foam turrets can be useful in killboxes, either to protect your colonists or to quickly clear a killbox of fire after a fight, where the limited space of the killbox makes up for the limitations in spray coverage. Additionally, the large range of the foam turret allows for easy protection behind colonists or in a more protective position while still being effective.
