IS8200-1 & IS8200-2 – The First in the Series
In 2008, TMCDAS introduced its first isolators: the IS8200-1 and IS8200-2.
The IS8200-1 remains the most widely used model in voice alarm systems and is designed for applications up to 200W audio power on the loop, with a maximum power consumption of 6W.
Note: Exceeding this power limit may cause malfunctions or permanent damage. The IS8200-1 is therefore the standard choice for most voice alarm evacuation concepts.
The IS8200-2 is technically identical to the IS8200-1 but is supplied in an IP55 housing for use in humid environments. Although it is used less frequently, the standard IS8200-1 generally performs equally well under such conditions.
IS8200-4 – Isolator with Integrated Relay for Volume Control
Introduced in 2022, the IS8200-4 was specifically developed for PAVA applications (Public Address & Voice Alarm).
In these environments, background music often plays an important role in addition to voice alarm functions. Since the required sound level for alarms is typically far too loud for background music, volume controls with integrated relays are commonly used.
The IS8200-4 significantly simplifies this setup. Instead of complex cabling between the wall-mounted volume control and the ceiling, a simple three-wire connection (signal out, signal return, and common ground) is sufficient. The bypass relay is now integrated into the isolator and can be controlled via an external 24V signal, for example from an I/O module of the fire alarm control panel.
Furthermore, this isolator supports up to 20W audio power and is prepared for future specifications up to 800W speaker cabling.
The IS8200-4 is fully compatible with existing networks that use IS8200-1 isolators. Always refer to the datasheet before installation.
IS8200-5 – High-Power Isolator
The IS8200-5 is a simplified version of the IS8200-4, without the components for volume control. It offers the same 20W audio power capacity and is likewise prepared for future 800W cabling specifications.
This isolator is ideal for applications using sound projectors and other high-power loudspeakers.
Like the other models, it is fully compatible with the IS8200-1 within a single loop. Always consult the datasheet for proper application.
IS8200-6 – High-Power Isolator with 24V Output
The IS8200-6 is a further development of the IS8200-5 and offers additional functionality for more complex applications.
In addition to 20W audio power, this isolator features a 24V output that is activated during a voice alarm. This output can be used to drive external relays, indicators, or other control elements, even in situations where no fire alarm loop is present.
A common application is the activation of flashers.
In modern large office environments with many workstations in open spaces, small acoustic cabins are increasingly being installed to allow people to make Teams calls or phone conversations without background noise. These cabins are often made of glass, which can attenuate sound by more than 40dB, making it impossible to reach the required voice alarm sound levels inside. This poses a safety risk, making visual signaling necessary.
The IS8200-6 offers a practical solution for this situation but does not meet the strict EN54-23 requirements for optical signaling. It is therefore intended as a pragmatic, “quick-and-dirty” solution rather than a certified one.
The IS8200-6 is equipped with an internal lithium battery that provides up to 30 minutes of reliable power when activated. The battery is automatically recharged via the loop and typically lasts around 10 years. Replacement is straightforward.
Note: A maximum of eight IS8200-6 isolators can be installed per ring loop. The IS8200-6 is fully compatible with all other models in the series. Always refer to the datasheet before installation.
Compatibility
All models in the IS8200 series are designed to work seamlessly together within a single ring loop.
Combinations of different isolator types are permitted, provided they are applied according to their respective specifications.
