La metáfora de abstractos y de inanimados

A multisensor detector with built-in optical smoke and heat sensor. The optical measurement chamber is provided with state of the art sensor technology, enabling the detection of open fires, smouldering fires and fires with high heat generation. Especially for open fires, the classical ionisation technology implemented in ionisation detectors is superseded by this new environment-friendly detection technology.

The detector is capable of identifying the TF1 and TF6 test fires described in the EN 54-9 specification.

The OT^blue multisensor is an intelligent detector with time-related signal analysis, signal correlation of the sensor data, decentralised intelligence, automatic function self-test. CPU failure mode, automatic adaptation to environmental conditions (drift compensation), alarm and operating data memory, alarm indicator and soft-addressing.

The detector is provided with an integrated isolator and a remote LED indicator can be connected.

Planning guide for powered loop installation This is a planning guide for esserbus^® PLus (powered loop) alarm devices. The alarm current of each alarm device is defined as load factor. When added up, the total load factor defines the loop length and the maximum number of alarm devices. The maximum load factor of all alarm devices must not exceed 96.

Altogether up to 127 bus devices per loop can still be connected. The "Load factor" download file for easier load factor calculation is available within our customer section at http://www.esser-systems.com.

Load factor calculation Example 1:

How many IQ8Alarm alarm signalling devices with load factor 3 can be connected to one loop?

96 (max. total load factor) : 3 (load factor) = 32

As shown in the table the max. loop length is reduced to 700m for this load factor.

Example 2:

Various types of alarm signalling devices are connected to one loop:

Load factor 4 x 807205 alarm devices with load

factor 3,0

= 4 x 3,0 = 12

+

27 x O2T/So multisensor IQ8Quad (802384) with load factor 2,0

= 27 x 2,0

= 54

total load factor = 66

The maximum loop length for a total load factor of 66 is 1300m (at a wire gauge 0,8mm).

Example 3:

For alarm signalling with sounder, 25 x 802384 IQ8Quad O²T/So detectors are installed - each in one office. What is the maximum loop length?

Load factor for one 802384 IQ8Quad O²T/So detector = 2 (load factor) 25 IQ8Quad O²T/So x 2 (load factor) = 50 (total load factor)

The maximum loop length is 1700 m (at a wire gauge 0,8 mm).
