Products Description
Mounting Position: Installed horizontally on the wall, typically a few inches below the ceiling.
Deflector Shape: Has a semi-circular deflector that directs the water spray pattern outward and downward.
Orientation: Can be horizontal sidewall (standard) or vertical sidewall (for special applications).
Connection Type: Usually features ½" or ¾" NPT/BSPT thread connection.
The heat-sensitive element (glass bulb or fusible link) breaks or melts.
Water is released through the nozzle.
The deflector redirects the water in a crescent-shaped spray pattern, covering the area below and outward from the wall.

FAQ
Q: Where are sidewall sprinklers typically used?
They are commonly used in:
Hotels, apartments, and residential buildings
Hallways and corridors
Offices and classrooms
Small rooms with limited ceiling access
Aesthetic installations where ceiling-mounted sprinklers are undesirable
Q: How does a sidewall sprinkler work?
When the temperature around the sprinkler reaches its rated activation point, the heat-sensitive element (glass bulb or fusible link) breaks, releasing the sealing cap. Water then flows and is deflected by the sprinkler plate, forming a spray pattern that covers the floor area beneath and outward from the wall.
Q: What spray pattern does a sidewall sprinkler produce?
It produces a half-parabolic or semi-circular spray pattern, distributing water outward and downward from the wall to cover the designated floor area efficiently.
Q: What are the common temperature ratings?
Typical activation temperature ratings include:
57°C (135°F)
68°C (155°F)
79°C (175°F)
93°C (200°F)
Other ratings are available for special applications.
Q: What finishes are available for sidewall sprinklers?
Common finishes include:
Brass
Chrome
White or painted coatings (for aesthetics)
Corrosion-resistant coatings (e.g., polyester or PTFE) for harsh environments
