Eaton O-1490V is a compact size and low power consumption optical-acoustic repeater for the remote signalling of alarms, failures or other by means of high visibility LEDs. Suited for the joint use with smoke and/or thermal detectors installed in false ceilings or floating floors, whenever external signalling is required. Versions with the suffix BZ are fitted with an internal buzzer for giving optical-acoustic warnings with either a constant sound or a flashing light. The device can be powered at either 12 or 24 Vdc. Installation is quick and simple thanks to the terminal connections and the possibility of fixing the device using the supplied double-sided tape.
