THE VISUAL ALARM DEVICE SO-Pd13 FOR FIRE ALARM SYSTEMS HOLDS DOCUMENTS ISSUED BY THE CNBOP-PIB:
The visual alarm device is destined for optical signalling in indoor fire alarm systems. The SO-Pd13 alarm device is destined to be used indoors.
The visual alarm device has a housing of non-combustible material, in which there are electronic components. In the upper part of the housing there is the source of light – LED diodes. In the cover of SO-Pd13 alarm devices there are power supply connections and a four-way microswitch (only a version with a built-in synchronization module), by means of which you can choose the working mode of an alarm device and delay time in relation to the “master” alarm device (only during operation in the “slave” mode).
The SO-Pd13 alarm device appears in three versions: 9m, 6m and 3m. Depending on the version, the coverage area differs (the area, where illumination is higher than 0.4 lx).
The SO-Pd13 alarm device conforms to the EN 54-23:2010 standard, enables creating a network of alarm devices which work synchronically (synchronization with the use of power supply line – the version of an alarm device with a synchronization module) or a set delay in relation to the master alarm device (from 0 s to 0.7 s).
During operation in the network, the mode of wave (delay from an alarm device master to slave) is not covered by the EN 54-23:2010 standard. An access to a microswitch is limited. To change the setpoint you should remove the microswitch cover.
After providing power supply, the SO-Pd13 alarm device generates an optical impulse signal of flash time shorter than 0.2 s. The frequency of generated optical signal is 0.56 Hz. An element which generates light are LED diodes placed in the upper part of the housing (shade) comprising an optical circuit. Depending on the alarm device version (a version with a built-in synchronization module) it is possible to create a network of alarm devices working synchronically or with the wave effect. In case of alarm device operating within one network, the “master” alarm device sends synchronization impulses on the power supply line. When building a network, alarm devices should be connected to the supply source through the FS-1 synchronization filter.
Creating alarm devices which work synchronically:
Before you start to create a net of alarm devices you should configure the working mode of an alarm device. In the device cover there is a four-way microswitch. Changing the microswitch position S/M in the position ON sets the mode “master”, position OFF mode “slave”.
In every network there can be only one alarm device “master”, which is responsible for generating synchronization impulses. Other alarm devices have to be set in the “slave” mode. Improper setting of the working mode leads to improper operation of the alarm devices net.
The alarm devices net may work synchronically or with a wave effect. The working mode of the network is set by adjusting a delay on “slave” alarm devices. If you set a delay on 0s value the network works synchronically. A delay is set by means of microswitches D0..D2 according to the table below.
|S/M||ON – Master Mode||OFF – Slave Mode|
|D0||D1||D2||Time of delay|
When creating a net of alarm device you should apply the synchronization filter FS-1. Failing to apply this filter may lead to damaging the source of supply voltage.
To open the signalling device: screw out the screw locking the base, turn the shade anticlockwise while holding the base, then separate the shade and the base.
To close the signalling device: fit together the markers. After that put together the device and turn in the direction marked with an arrow (the sequence in the drawing). On closing, lock the base by screwing in the locking screw.
