The IU 370 is an analyser and relay unit, used to connect the GD 330, GD 370 and GD 470 glass break detectors to a control panel. Up to 10 detectors (max. 8 GD 470) can be connected to an analyzer unit.

IU 370 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.
