MAGENTA
DIGITAL GLASS-BREAK DETECTOR
magenta_en 03/13
The MAGENTA detector enables detection of plate, tempered or laminated glass breaking.
The detector will report the alarm when a low frequency sound (impact) followed by a high
frequency sound (glass-break) are registered. The high-frequency channel is analyzed for
four seconds from receiving the low-frequency sound wave.
1. Features
Advanced dual path signal analysis.
Stepless regulation of detection sensitivity.
Low supply voltage signaling (voltage drop below 9 V ±5%).
LED indicator.
Tamper protection in 2 ways – cover removal and tearing enclosure from the wall.
2. Electronics board
terminals:
+12V - power input +12 V DC (±15%);
COM - common ground;
TMP - tamper output (NC),
NC - alarm output (NC).
tamper contact.
red color LED to indicate
detection of low-frequency sound – ON for 0,5 seconds;
alarm – ON for 2 seconds;
test mode – short flash every 3 seconds;
low supply voltage – ON.
detector configuration pins:
TEST – enabling/disabling the test mode. In the test
mode, the detector reports an alarm when it detects a
high frequency sound. The INDIGO TESTER is
recommended to test the detector. The test mode is
enabled when the jumper is set in ON position (Fig. 2).
LED – enabling/disabling the LED indicator. The LED
indicator is enabled when the jumper is set in ON
position (Fig. 3).
potentiometer for the adjustment of detection sensitivity
(Fig. 4).
