DG457 V1.0
Digital Glassbreak Detector
Operational Modes
The DG457 can function in two different operational modes: combus mode or relay mode. This option can only be configured using the J3
jumper:
Relay Mode: (J3 = OFF)
When set to Relay Mode, the DG457 functions as would any standard motion detector by communicating its alarm and tamper signals
via relays. The GRN and YEL terminals are not used in relay mode. In Relay Mode, the detector’s settings can only be modified using
the jumpers (see figure 1).
Combus Mode: (J3 = ON)
When set to combus mode, the DG457 communicates alarm signals, tamper signals, data and detector settings via the panel’s 4-wire
combus. The detector’s relay output always remains active even when set to combus mode and can be used to activate other
devices.
In combus mode, the motion detector can be modified using the jumpers or by entering module programming mode.

Section Test Mode
[002] Keypad Method
Entering (123) initiates test mode.
Jumper Method
Remove and replace Jumper 1 (J1).
Test Trek Method
With the TestTrek unit (v2.0 or higher) approximately 2.5m (8ft) from the GlassTrek, hold the test button down. A beep
followed by a series of beeps is produced which signals the GlassTrek to enter test mode.
Section Voltage Meter
[900] Displays [3-digit number] which represents input voltage x 10
e.g. [133] = 13.3V
