Addressable heat detector 920E works with our addressable MN300 panel via a 2-wire bus system
Addressable heat detector 920E works with our addressable MN300 panel via a 2-wire bus system.
The detector realizes real-time acquisition of the heat concentration data and sends back the data to a fire alarm control panel. It can also receive and execute the control commands given by a fire alarm control panel.
The detector is suitable for such industrial and civil buildings that have a great deal of heat when fire takes place, such as kitchens, boiler rooms, generator rooms, drying workshops and smoking rooms and is not suitable for places with a great deal of smoke but little heat.
Product features
It can realize electronic coding and rewrite the address via coder.
With a single-chip microcomputer, it can realize real-time data acquisition and processing, realize a curve tracing for the field situation.
It has a temperature compensation function and a sensor fault detection function(fault reporting to fire alarm control panel).
Non-polarity, two-bus connection that ensures convenient installation and maintenance.
Designed with an upper cover and a lower cover and installed on an independent base, it can be installed, debugged and maintained conveniently.

11.Installation height: <=8m
12.Protection area: about 60m2. For details, see related provisions in GB50116-98 Code for Design of Automatic Fire Alarm System.
13 Installation and debugging
Determine the location, mounting distance and numbers for mounting the detectors in the protection area according to relevant provisions and regulations of GB50116-98 Code for Design of Automatic Fire Alarm System and GB50166-2007 Code for Installation and Acceptance of Fire Alarm System.
A self-contained complete base is necessary during the installation of a detector. As shown in Fig.5, the model, the external dimensions, the mounting hole diameter and the mounting hole spacing of the base are DZ-910, 100mm×22mm (diameter×thickness), 5mm and 56mm~64mm respectively.
Wiring requirement:
It is proper to use RVS twisted pairs with a section area of equal to or larger than 1.0mm2 for the signal buses L1 and L2.
Specific installation and debugging methods:
1.Make sure the type of the detector matches the type of the host machine of the fire alarm control panel;
2.Use two M4 screws to fix the matched mounting base on the designated position via the mounting holes C and D shown in Fig.5, as instructed in the construction drawing and make sure the matched mounting base has been firmly installed.
3.Use a coder to make the detector coded according to the detector address on the construction drawing.
4.Disconnect the power supply of the fire alarm control panel and connect the detector correctly according to the construction drawing.
5.Place the indicator at position A of the detector (see Fig.1) and position B of the base (see Fig.5), align them with each other, insert the detector into the base and turn the detector clockwise until it is firmly locked.
6.After all the products are installed and checked, connect the power supply of the fire alarm control panel and conduct automatic login.
7.when automatic login is success, the red indicator of the detector will blink once about every 12 seconds, which suggests that the detector has begun to operate normally.
8.Finally conduct an alarm test for the detector through some special tools or direct hot air gun blowing. After the detector gives a fire alarm, the indicator will remain lit and the fire alarm control panel will simultaneously give corresponding alarm prompt information. After the alarm test, reset the fire alarm control panel and restore to the monitoring status.
Precautions
1.A detector can not share an address with other equipment in a single bus circuit, or else an address conflict may occur.
2.Never dismount the protective cover delivered with the detector too early after the field installation and before the use of the detector, or else the detector may be contaminated.
3.It is not permitted to use open flames (such as lighters) to firing thermistor during alarm tests, so as to avoid damage to the detector. It is recommended to use a hot air gun and other heating equipment in a simulation alarm test.
4.The protection area and quantity of the detectors should comply with relevant provisions in GB50116-98 Code for Design of Automatic Fire Alarm System and GB50166-2007 Code for Installation and Acceptance of Fire Alarm System. .Matched host machine: fire alarm control panel (such as MN300)
