DI-9101E Intelligent Combination Heat Photoelectric Smoke Detector
Description
DI-9101E Intelligent Combination Heat Photoelectric Smoke Detector integrates photoelectric detection and fixed temperature and rate of rise detection technology by combining smoke sensor and semi-conductor heat sensor in mechanism and circuitry structure. Just because of the combination of smoke detection and heat detection, it not only overcomes the disadvantage that detectors using common infrared scattering technology are insensitive to black smoke with small particles, but also can pick up fire with obvious rise of temperature such as alcohol flame, thus extending its application range.
Features
Strong environmental adaptability due to drift compensation.
Self-diagnostic.
Reed switch testing.
Removable innovative sensing chamber, easy for maintenance.
Dirty chamber checking.
Fire LED allows 360°viewing
Remote indicator output available.
Polling LED can be set to close.
2 levels smoke sensitivities programmable, level 1 complies with EN 54-7. Heat part complies with EN 54-5.
Connection and Cabling
There are four terminals with numbers on the base.
1&3: Loop connection (polarity-insensitive)
2: Positive terminal of remote indicator
4: Negative terminal of remote indicator
Recommended Cabling 1.0mm2 or above fire cable is recommended, laid through metal or flame-retardant conduit, but subject to local codes. Different color cables for remote indicator are used to avoid wiring mistake
