Addressable automatic combined smoke detector

 

Purpose

 

For operation in heated and unheated premises in mobile objects of railway transport 

 

Functions 

• Responds to :

- appearance of smoke and temperature rise;

- normally closed contacts discontinuity;

- normally open contacts closure

• By the nature of reaction to environment temperature: maximum, thermal
• By the principle of responding to smoke: optical, infrared, spot

 

Technical characteristics

• Supply voltage, V: 10...14
• Power consumption at 12 V supply voltage:

- in standby mode, W: no more than 0,006

- in alarm mode, W: not more than 0.3

• The sensitivity of the detector to smoke, dB / m: 0.05 ... 0.2
• The sensitivity of the detector to temperature:

- by threshold value, ° C: 50, 62, 70 *

• Resistance of closed contacts connected to circuits "0" and "NO", ohms: not more than 5
• Resistance of open contacts connected to circuits "0" and "NC", Ohm: 200
• Response time of the detector, sec:

- in smoke environment: no more than 5

- at the rate of temperature increase of 30 ° C / min. (from 25 ° C): 39 ... 128

- at contact opening/closing: 4

• Address field capacity of the detector : 1...54
