Nest Protection

hotoelectric smoke sensor (opto) is suitable for most applications giving the fastest response to slow burning or smouldering fires which give rise to large visible smoke particles.

Opto-heat sensor will respond better to fast clean burning fires yet maintain the advantage of optical sensors when detecting smouldering fires. The thermal enhancement of this sensor allows a higher alarm threshold which provides a greater rejection of false alarms. The sensor will also give an alarm at temperatures above 135°F.

Rate of rise with fixed heat sensor settings will detect a rapid increase in temperature or temperatures above 135°F and should be used in environments where the ambient conditions might cause false alarms if smoke detection were to be used, for example where there is a high level of dust, fumes, steam or smoke under normal conditions.

Fixed heat sensors settings will detect temperatures above 135°F or 194°F and should be used in environments where the ambient conditions might cause false alarms if smoke detection were to be used, for example where there is a high level of dust, fumes, steam or smoke under normal conditions. For photoelectric and opto-heat operation the sensor automatically compensates for gradual increase in the scatter signal due to contamination e.g. dust build up.

• Built-in short circuit isolators
• Stylish low profile design
• 360º viewable LED design
• Removable detector chamber
• Drift compensation

• Plug and play - no hard addressing required
• 'Clean me' feature means sensor can be cleaned on site using Eaton's manual cleaning procedure
• The programmable heat sensor reduces the number of parts required in the system
