ower Supply Rating

It should be noted that the eurösec GT480 has 1 Amp available for the full system. However,

for the purpose of compliance to EN and PD6662 standard, the capacities of the power

supply have to be specified differently.

For a Grade 2 system you have 72 hours to charge the battery. With the GT480 Control

Panel, 90mA is available for battery charging. This defines a theoretical maximum standby

battery capacity of 8.0Ah and a maximum of 666mA available for system power.

If a smaller capacity battery is used then the rating has to be reduced accordingly.

For example: If a 7Ah battery is used it will recharge in 72 Hrs and will theoretically provide

910mA (1000-90mA) for the system. However, the supply rating for that system under

PD6662 is still 7.0Ah/12hrs = 583mA.

Sounders, detectors and other auxiliary items should be included when calculating current

drawn by the system. Any damage caused through overloading the Control Panel Supply will

not be covered by the warranty. We recommend that additional power supplies are used to

supply detectors on long cable runs.
