FIRE DETECTION - Urmet

Heat detector
RTS/4 cod. SD4C00123
IP55 heat detector based on the deformation of a bimetallic element which
closes a dry contact as the temperature is reached.
• This makes the detector easy to be interfaced with any board type.
• The detector can operate based on the type of heat probe being used as
follows:
DF: Gradient detector. The intervention only occurs when temperature
increment is higher than 13 °C per minute.
SD: Semidifferential detector. The intervention always occurs as calibration
temperature is reached; further, an intervention lead occurs when temperature
increment is higher than 15°C per minute.
MAX: Maximum temperature detector. The intervention only occurs when
calibration temperature is reached.
• Code SD4J00123 is referred to a detector with a 60° C calibration
temperature. Different grades are available to specify in the command.
• Operation principle: Bimetallic element deformation
• Protection degree: IP 55
• Working temperature: 190 C° MAX
• Relative humidity: 98%
• Weight: 0,4 Kg
• Bimetallic component: Nilvar-Brass
• Regulation range: -40 + 190 C°
• Intervention threshold: On Request /mod SD Max 88 C°
• Alarm condition: Normally closed contact
• Contacts current carrying capacity: 2,5 A
• Working voltage: 48 Vdc
• Enclosure material: Aluminium alloy
• Dimensions: 92x167x67 mm
RTS/6 cod. SD3C00123
IP65 Special heat detector based on the deformation of a bimetallic element
which closes a dry contact as the temperature is reached. This makes the
detector easy to be interfaced with any board type.
