Description

Use

The SO-PD12 beacon uses an LED to indicate the occurrence of a hazard inside buildings.

Construction

The SO-PD12 beacon consists of two main parts. The first of which is the right alarm device in a housing of non-combustible material. It contains supply voltage terminals and change-over switches which allow you to select one of fifteen different flash effects or to turn on continuous lighting. The second part – a socket is a mounting element which fixes the alarm device to the ceiling or wall by PIP-3AN cable junction box or by means of two screws and anchor pegs.

Opening

To open the alarm device you should: screw out the blocking screw, twist the shade to the left while holding the base, then move apart the shade and the base.

Closing

To close the alarm device adjust the markers, then assemble the device and twist it to the direction marked with an arrow (sequence shown in the drawing). After closing, screw in the blocking screw.

What effect does the cross-section of the wires have on voltage drops?

The larger the cross-section of the wires, the lower its resistance and, consequently, the lower the voltage drops. For example, the HDGs 1x2x1.5 mm2 cable has a core resistance of R = 12.1 Ω/km, while the HTKSH 1x2x2.5 mm2 cable has a core resistance of 7.41 Ω/km. In order to calculate the voltage drop, the length of the line should be taken into account and a safety factor related to the length of the wire that may be caught in fire (increase in its resistance) should be assumed.

What is the effect of temperature on the resistance of wires?

The resistance of the wires changes as a function of temperature. According to the ISO curve, the temperature of the PH30 cable operating in fire conditions will be 822°C after 30 minutes and its resistance will increase 4.5x! The temperature of the PH90 cable after 90 minutes will be approximately 955°C and its resistance will increase by almost 5.3x! This should be taken into account when designing the installation and appropriate safety factors should be adopted. The resistance of the cable affects voltage drops and, consequently, whether the device will operate in hazardous conditions or not. Voltage drops can be compensated by increasing the cross-section of the conductors.

How to read and what does the IP protection degree mean?

Degrees of protection provided by enclosures (IP code) is the full name of the PN-EN 60529 standard. It contains a classification of degrees of protection provided by enclosures of electrical devices with a rated voltage up to 72.5 kV.

The code consists of:

  • first characteristic digit (against the ingress of foreign solids)
  • second characteristic digit (against water ingress)
  • additional letter (before access to hazardous parts)
  • supplementary letter (supplementary information)

For example, according to EN 54-3, EN 54-23 standards, external fire alarms (type B) must provide IP33C protection. This means that the housing provides protection against:

  • access to hazardous parts with a tool (2.5 mm probe)
  • foreign bodies with a diameter of 2.5 mm and larger
  • water spraying (at any angle up to 60° from the vertical)

How to calculate the required battery capacity for the power supply?

The required capacity K [Ah] of the battery(s) can be calculated from the formula:

K=1,25*(I1*t1+I2*t2)

Where:

K – required capacity, in ampere-hours (Ah)

t1 – support time, in hours (h)

t2 – alarm time, in hours (h)

I1 – total current consumed by the fire alarm system in the event of failure of the energy source, in amperes (A)

I2 – total current consumed by the fire alarm system when alarming, in amperes (A)

Is it possible to manufacture the optical unit of the SO-WD and SO-PD signalling devices in a different color?

Yes, it is, though it depends on the number of ordered alarm devices, such devices have a different price. If you are interested, please send an inquiry to us on biuro@w2.com.pl.
