TECHNICAL PERFORMANCE
Operating voltage: Stand-by current/alarm current: Sound frequency: Sound level: Function: 4.5 to 15.0VDC 0 /17 mA 4 ± 0.5 KHz >83dB/10cm @ 12VDC In case of missing or very low frequency pulses an acoustic signal will be generated (the sound level varies by the operating voltage). After eliminating the failure the acoustic signal stops after reset only.
