item_suit is a point entity available in 
Half-Life 2 series.
This represents the Mark V Hazardous Environment Suit, Aka HEV-Suit, when not being worn by the player. It is an upgraded version of the Mark IV suit that Black Mesa employees were required to wear when handling anomalous materials (in Half-Life).
This is only a pickup to enable suit charging and the HUD (EquipSuit()).
Placement Tip:This entity should be placed at least one unit above the ground, or it will not be visible in-game.
Note:This entity is also available in 
Portal 2, but most of the functions are disabled or do not work at all, including the HUD. You can still charge armor.
Bug:
Half-Life 2: Episode One for some reason swaps the original texture with a 32x32 pixel texture. 
Half-Life 2: Episode Two also uses it, due to the gameinfo mounting the EP1 content as well.Fix:Pack the original textures into a mod, to be used in the episode's "Custom folder".Alternatively, mods downloaded from the Steam Workshop will overwrite the models of all game versions, circumventing this issue.
Suit sounds
When player receives damage, mechanical voice speaks and suit starts beeping. Suit responds to various kinds of damage including blood loss from bullets, fall from height, slashes from zombies and bites from poisonous headcrabs.
The volume of these sounds can be controlled with float console variable suitvolume. Accepted values range from 0 to 1. Set to 0 to mute suit sounds completely.
Suit Jingle
When Dr. Gordon Freeman enters his suit in Half-Life 2, a small tune starts playing.
To set this up, have the item_suit output OnPlayerTouch target an ambient_generic that's placed close to the suit with the input PlaySound.
The song used in Half-Life 2 is called song_trainstation_05_suit (
music/hl1_song11.mp3), but there is apparently also a tune called song23 (music/hl2_song23_suitsong3.mp3) that, judging by its name, was intended for the HEV suit.
Flags
Short Logon (Deprecated) : [1]
- When checked, doesn't play the logon (
hl1/fvox/bell.wav) sound. In Half-Life, this flag was used to cut the HEV suit's long logon speech, but was cut from Half-Life 2 along with many HEV voicelines. (Dr. Kleiner replaced the feature with a short bell)
