Honeywell VARIODYN D1 User Manual

Installation Instruction VARIODYN
®
D1 System
56 FB 798663.GB0 / 05.19
7 Power Amplifiers (PA)
The power amplifier modules are each equipped with two or four amplifier channels. These are controlled and
monitored by the VARIODYN
®
D1 modules DOM4-8 or DOM4-24.
• Correct functioning of the VARIODYN
®
D1 System is only ensured with a power amplifier and a
suitably configured DOM.
• The described functions depend on the amplifiers required for the specific building.
Dimensioning / output power
An amplifier with a suitable output power must be selected for supplying the connected loudspeakers. The
selected amplifier must ensure that the required sound level is achieved with the corresponding loudspeakers.
In principle, it is practical to select an amplifier with higher output, since it can generally achieve better sound
results - particularly with high dynamic signals like voice signals. (low distortions, prevention of clipping and short-
term shutdowns due to overloading when operated under load).
Generous amplifier dimensioning provides for expansion options if the voice alarm system needs to be expanded
at a later date, e.g. due to changed use / apportionment of the alarm areas.
Ventilation
Temperature-controlled forced ventilation ensures that the temperature stays low and remains even. In the case
of cabinet installation, make sure there is sufficient ventilation (incoming and outgoing air).
• The air outlet of the device or device fan may not be blocked or disrupted!
• Run installation cables at a good distance.
• In the case of cabinet installation, make sure there is sufficient ventilation
(incoming and outgoing air)!!
Type Output power as per EN 54-16 Part No.
