Nittan EVC-P Photoelectrical Optical Smoke Detector

Nittan EVC-P Photoelectrical Optical Smoke Detector

Nittan EVC-P Photoelectrical Optical Smoke Detector with 375 Ohm ResistorUsing a simple but effective technique the EVC-P Optical Detector incorporates a chamber housing an Infra-Red IR LED light and a photodiode light detector set at an obtuse angle preventing it from seeing the light. When smoke enters the chamber the light bounces off the smoke particles and strikes the photodiode causing it to generate an alarm condition when a set threshold value is met.The EVC-P Optical Detector is therefore more sensitive to larger smoke particles which tend to be caused by smouldering fires rather than fast flaming fires.OperationThe smoke chamber of the EVC-P is constructed so that light cannot enter from outside but smoke can pass through the chamber slots. The EVC-P utilises the light scatter sensing principle. The LED pulses every 8 seconds to maintain a low monitoring current. A quick charge time 20 seconds is also achieved. The detector incorporates an alarm verification function which requires two successive pulses before an alarm is given.The interval between the first and second pulse is automatically reduced to four seconds after the first alarm level is monitored. The detector design provides strong immunity to air velocities contamination and RF interference. The geometry of the smoke chamber and optics support assembly is designed to give the best possible signal to noise ratio resulting in excellent response characteristics.Key FeaturesOmniview 360 LEDInternal Alarm Current Limiting ResistorWide Operational Voltage Range 12v-32vOptical Detector

Kidde NC-DBD-W Conventional Detector Accessory - Diode Base White

Kidde NC-DBD-W Conventional Detector Accessory - Diode Base White

KiddeNC-DBD-W Conventional Detector Accessory - Diode Base WhiteThe NC-DBD-W is an NC series surface mount first-fix base offering and integrated diode. It allows any NC Series conventional point detector to be inserted removed or replaced without rewiring using an easy twist and lock action. The integrated diode allows support for BS5839 head-out functionality. The NC-DBD-W supports a remote indicator connection.Ease of InstallationForming an integral part of the detector assembly NC Series standard bases are provided with key-hole slots for screw fixing direct to ceiling structures or conduit boxes. Large rear cable entry allows for easy wiring to the base. For special applications a base accessory is available for surface installations ensuring an easy and practical installation.Ease of Wiring TestingClearly marked terminals ensure correct and secure wiring termination for zone and remote indicator connections.Ease of UseInserting the NC Series detector into the base is accomplished with a simple turn and lock mechanism. To prevent unauthorised removal of a detector from its base an easy-to-activate locking mechanism is incorporated into all NC series detectors. If activated a detector can only be released from its base using a dedicated tool.Common first-fix mounting base for all white NC-Series detectorsPre-installed diode for BS5839 head-out supportA selectable detector locking mechanism protects against unauthorised removalLarge rear cable entry with ample space for cablesFlexible installation fixture with first fix screw feature reduces installation time and effort
