Amplifier and Speaker Pre-Operation Checkout (Non-Active Mode)
With an ohmmeter measure the speaker terminal strips at the bottom of the backplane
motherboard for each amplifier and measure the resistance at the output of that amplifier.
The resistance is approximately 4.5 ohm. A different reading indicates a possible
wiring error or faulty driver in the speaker array. Since the 400 watt speaker circuits are
comprised of two sets of series wired speaker drivers connected in parallel, if one of the
drivers in a circuit were to open, you measure approximately 9 ohm. If you are using
200 watt DSA speaker combinations, you measure a 10.8 ohm reading across the 200
watt load.
The output sound level of a siren is capable of causing permanent hearing
damage at short distances; sound levels may exceed 150 dB. Therefore,
always wear adequate hearing protection when performing tests or
maintenance on the siren.
Supply power to the siren to charge the batteries for a period of 24 hours prior to
operation of the siren in order to ensure full charge of the batteries. (Alternatively,
charge the batteries externally before installation following the battery manufacturer’s
recommendations.) Typical battery voltage is 27.2 Vdc when fully charged at room
temperature. (See the Specification section for details.)
