Description
The NS1-P2 thermal detector is a fully mechanical device.
Its construction technology make it robust and reliable, suited for industrial and harsh enviroment where electronics devices are not suitable.
NS1-P2 is composed of two fixed alarm thermal detector mounted on IP65 enclosure.
NS1-P2 MAX: Fixed temperature detector. The detector is activated exceeding the maximum temperature .The alarm temperature is calibrated as required by customer over a range of -20÷190°C.
NS1-P2 detectors are suitable for fire detection and extinguish systems.
Normally, is recommended a temperature of 30÷35°C above the maximum operating temperature of the environment .
The selection of the most appropriate categories of detectors is must be evaluated according to the characteristics of the environment.
NS1-P2 detectors are common mounted in vertically position but is possible to install horizontally.
The Calibration accuracy for all models is ± 5°C.
The periodic system test of the heat detectors consist by introducing it a heat source that not exceed by 20% the fixed alarm temperature of the detector.
(for example for a heat detector with an alarm point of 100°C we can heat at maximum of 120°C)
Electrical specifications
NS1-P2 detectors are available N.O and N.C.
The maximum current contact is 2,5 A at 48VDC AC-DC (resistive load).
Mechanical specifications
NS1-P2 detectors are made from:
Body sensor:
Material: Brass UNI 5705-65/Stainless steel AISI 304.
Brass version is nickel plated to protect it from corrosion.
For temperature above 150°C the body sensori s made of stainless steel AISI 304.
Enclosure:
The detectors are mounted in a die-cast light aluminium alloy enclosure with IP65 degree of protection. dimensions are 92x92mm with threaded ½” GAS entries.
A bracket connection terminal in installed inside the enclosure for heat detector and external connections.
