Every effort has been taken to keep the ACT Luminaire Battery Tester a quick & user friendly product. Firstly, there are no complicated settings or switches. Once connected to the battery terminals, all LEDs will indicate briefly to confirm operation & will automatically determine if the battery type is a 2.4v/4.0 Ah or 3.6v/1.5 Ah Ni Cad cell – yet another time saving feature. The yellow testing LED will flash continuously until the red fail or green pass LED indicates battery condition. This pass or fail indication will all happen within minutes. The user should test the battery ONCE to simulate a 1 hour test or TWICE for a full duration test. Dramatically reduces time taken to perform the 1 hour & full battery duration test as required by BS5266 Tests 2.4v/4.0 Ah & 3.6v/1.5 Ah Nicad batteries in st&-alone emergency lighting systems in minutes Identifies defective batteries in seconds Leaves sufficient capacity after a full battery duration test to power the emergency light for at least 30 minutes Simple in operation – no buttons or complicated settings Automatically detects which battery voltage type is fitted Allows ALL emergency lighting luminaires to be tested during one service visit Enables engineers to work more effectively, encourages more businesses to offer this test as a service & ultimately, save more lives.
