EN 54-5 classification
A1R
Input voltage
24 V DC
Input current
maximum 20 mA
Installation position
Ceiling mounting
Terminating resistors
2 × 43 kΩ, integrated, can be disconnected
Alarm output
Potential-free relay output, normally closed contact maximum 24 V DC /
maximum 1 A
Detector test
Alarm triggering
ú
with test magnet near the magnetic sensor
ú
with heat detector testing device
The detector test using a test magnet tests the electrical components.
The detector test which forms part of the regular testing of the hold-
open system must be carried out using a heat detector testing device
(see chap. 6.3).
