5.1 Browse events
The BHS-3000C system stores more than 100 events in its event
memory. You can review the events from installer programming.
Select Option 7: Browse Events from the Home Menu. The
display will show the following selections:

the events in event memory, select Clear Events.
5.2 Status LED
The system's bus devices provide you with system status information
by blinking the status LED at different rates. Specifically, the status
LED blinks to indicate whether the device is properly configured and
whether or not it is communicating with the panel.

5.3 Troubleshooting specific problems
5.3.1 System wilt not initialize_
Condition: When power is applied to the system, it fails to
operate.
Indications: None of the system components operate properly.
Possible causes:
• The backup battery may be defective.
• The transformer may be defective.
• The breaker switch may be thrown.
• A peripheral device may be defective.
Solutions:
• If the battery is completely discharged, the panel will not
power up until the battery has been recharged to approx.
11.5 VDC. Allow sufficient time to recharge the battery and
monitor the voltage level.
• If the battery or transformer is defective, replace it. (Disconnect
the electrical power to the panel before investigating.)
• Move the breaker switch to the ON position.
• Remove all keypads and attempt to initialize the system. If
successful, reconnect the keypads one at a time, replacing
any keypad that does not work.
• Remove all devices connected to AUX power and attempt to
initialize the system. If successful, reconnect the devices one
at a time, replacing any one that does not work.
• If none of these solve the problem, replace the panel.
• Panel will not power up on battery unless the siren output is
momentarily shorted several seconds after the battery is
connected.
The LED blinks one to five times, pausing for two seconds before
repeating the pattern. To determine the system's status, count the
number of blinks, and compare it to the table below.

5.2.1 Determining the Device Number_
Each bus device is automatically assigned a Device Number, or
polling address, during the Learn Devices procedure. You can
obtain the Device Number by doing the following:
1. Press the device's Service Button. (The Service Button is
located in the lower right-hand comer of the PCBs of the
ZEM, the keyfob receiver, and the keypads.)
2. The Status LED (located near the Service Button) blinks the
Device Number in a decimal format. Zeros are indicated with
a continuous two-second pulse; digits are separated by a
one-second pause. There is a 2.5-second pause at the end
of the number.
The example below shows how Device Number 12 would be
broadcast:
5.3.2 Keypad does not work at startup_
Condition: When first installed, the keypad is not able to
communicate with the control panel.
Indications:
• The keypad does not respond when a key is pressed.
• The keypad icons and/or LEDs are not lit.
• The keypad does not appear on the programmer's list of
learned devices.
Possible causes:
• The keypad's black and red wires are not connected to the
common and AUX terminals, respectively.
• The keypad wires are damaged.
• CLK and DATA wires are reversed.
Solutions:
• Verify that the panel is receiving power at the AC inputs.
• Verify the wiring connections, replacing any wires that are
damaged.
• If none of these solve the problem, replace the keypad.
5.3.3 Keypad stops communicating
Condition: One or more of the system's keypads are no longer
able to communicate with the control panel. The keypad(s)
previously operated properly.
Indications:
• The siren clicks twice, then pausing for two to three seconds.
(The user can silence this by pressing the CANCEL key on an
operative keypad.)
