The IU 300 is an analyser and relay unit, used to connect the GD 335 and GD 375 glass break detectors to a control panel. Up to 20 detectors can be connected to the device.

IU 300 monitors resistance changes in a balanced circuit. It is possible to program it for either manual reset (Latch) or auto-reset after two seconds.
Note: An alarm from a single detector activates the alarm relay on the unit.
