Fig. 84: Power supply
To check the power supply for the additional external devices, the voltage is meas-
ured at the rear of the system (Fig. 84/1). For a system connected to the network the
voltage must be 26.8
0
/
-0.3
Volt. The voltage can be set exactly at the potentiometer
(Fig. 84/2) of the power supply.

Cover seal
The seal on the inside of the cover is to be checked for damage and replaced where
applicable. In the event of damage to the cover seal, it is possible that the air flow
monitoring is not functioning correctly.
11.2.30
Checking the total weight
To prevent a gradual process of extinguishing agent loss, the total weight of the
system must be checked and reported. A calibrated scale for loads of up to 20 kg
and 10 g resolution is needed for this.
11.2.31
Testing the release
L
CAUTION
Risk of injury from faulty release!
A faulty release of the system may cause injuries and property damage.
● Block the system before the release is tested to avoid unwanted extinguishing.
This applies to both Type DET-AC III Master and for Type DET-AC III Slave.
A check of the alarm function is performed to test the function of the fire detectors.
The test gas "Solo A3"
[company No Climb]
(part no. 905904) is needed for this.
