Description

DC-M9101 Conventional Combination Heat Photoelectric Smoke Detector integrates photoelectric detection and fixed temperature 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. On detecting a fire signal, it can change its own current to transmit the signal to fire alarm control panel (FACP) or addressable zone monitor unit. The detector keeps illuminating fire LED until it is reset by power-down. 

Connection and Cabling

The detector connects with UL-certified products such as I-M9300, DI-M9319 module and intelligent control panels.

Please install the base according to following steps:

1) Locate mounting holes on the rubber layer of the base according to the holes on the back box, and punch the holes with a screwdriver.

2) Count the number of cables needed and punch correct quantity of holes with a screwdriver on the rubber layer. Thread the cables through the cable entry holes.

3) Install the base onto the back box with screws. Warning: Do not punch mounting holes and cable entry holes bigger than needed. Do not punch more holes than needed.

There are four terminals with numbers on the base. 1: Detection zone positive IN 2: Detection zone positive OUT 3: Detection zone negative IN and OUT 2: Positive terminal of remote indicator 4: Negative terminal of remote indicator It connects a 4.7k/1w resistor between number 2 and 3 at the end of the base
