Bitwriter® commands can control para- meters such as Turn on Delay, Fan Control, Input Gain adjustment, and also place the amplifier into a monitoring state for commands from an ESP2 equipped alarm.

1.Turn-On Delay - 0.75, 1.00, 1.25, 1.75, 2.25, 2.75, or 3.25 seconds. 1.75 seconds is the factory default setting.

2.Fan Control - AUTO - The fan will automatically turn on when the internal temperature exceeds approximately 40 deg C. The ON option causes the fan to operate whenever the Amplifier is on. Use the ON option if you are using the external FAN port to drive optional LED tubes. In the OFF mode the external FAN port is disabled.

3.Service Code Display - The Directed ESP® Engine stores up to seven previous faults for later replay. The Service Code Display allows the installer to step through the fault history.

-OFF - In the OFF position, the amplifier operates normally.

-FLASH CODE ON LED - the last recorded fault is "replayed" on the ESP® Indicator LED. If the unit has never recorded a fault, the ESP®

Status indicator will not flash.

-RESERVED - no function, reserved for future use.

-CLEAR LAST FAULT - Clears the last fault. Note that this allows you to see previous faults prior by back- stepping one at a time through the fault history.

4.Input Gain Range - The sensitivity on the gain control can be limited to specific ranges. The DEFAULT position allows adjustment over the full range of amplifier sensitivities. There are 4 other ranges 0.5-1.0V, 1.0V-2.0V, 2.0-4.0V, 4.0-8.0V.

5.Input Gain Adjustment - In the LOCK position, the gain range and gain control can be locked out to prevent accidental mis-adjustment. The Default mode is UNLOCKED.

6.Valet - Selecting ENABLE allows the amplifier to monitor valet signals from the alarm system. The ampli- fier will not power up once remote power is removed when the Valet monitoring mode is ENABLED and the alarm system has been set into Valet mode.

Note: To make use of the Anti-theft or Valet features, the amplifier must "learn" which transmitters are asso- ciated with the currently used alarm system. See item 8 below.
