Issue
When does the D128 dual phone line switcher module indicate a phone line failure?
Solution
An amber phone line status LED lights on the D128 module when the control/communicator measures less than 25VDC or 10mA of current across the tip and ring of the telephone line. The D8112 and D9112 monitor the telephone lines for a programmable interval before indicating a trouble condition.
Issue
What would cause the D6112 panel to send a zone 9, when arming the system?
Solution
D5200 Programing - 7.10 or 8.10 = Comb ID is set to yes in the program of the panel. With this
prompt set to yes in the program, a zone 9 is sent when the panel is armed
by the remote programmer, or command 1.
Overview: Charging circuit is overcharging the battery. Panel is damaged.
Issue
Reading 15vdc on the battery charging circuit.
Solution
Replace the panel. The voltage regulator is failing on the panel.
Overview: D4112 doesn’t arm or anything when code is entered at the keypad.
Issue
Nothing happens. Doesn’t arm or anything when code is entered at the keypad.
Solution
Connect programmer using coiled cord.
Plug in plastic RJ phone type plug into COMMUNICATOR female connector on 5200
Plug brown connector on other end of coiled cord to programmer connection on 4112
Press ON button on 5200
Type in password at PASSWORD prompt, press enter.
Top Line of 5200 shows PRODUCT HANDLERS
Using the up/down arrows scroll down until 4112. Please blinking cursor on 4112
Press RED Enter Group button
Place cursor on NEWRECORD
Short the Standby pin on 4112 to ground momentarily
Press RECV(COPY) button on programmer
Receiving will be displayed at the top line of the 5200 Display
Scroll down using arrow down key until cursor is on 2 PASSCODES
Press ENTER GROUP button
Passcode1 should have 234 in the field.
To change field, press CLEAR key and type in the code to be used.
Press enter
The code is restricted to 4 characters but the user enters a prefix of 1, 2, 3, 4, 5…depending upon the slot. Example: PASSODE1 shows 234. The user code will be 1234
*** NOTE: Also make sure that the panel has a valid and functioning analog line. The functionality of the system is dependent upond successful communications.
Issue
On 2000 series panel, point codes are programmed for points between 9 and 24. When programmed points are tested the keypad reads "PT(#) PT DISABLED (where # is the number of the point being tested).
Solution
Pt text (Point Text) was never changed from default that read "PT(#) PT DISABLED".
Issue
How many zones can be programmed on the D8112G2?
Solution
The D8112G2 is capable to have 8 master zones that may be expanded to 134 individual zones of protection.
Issue
How many Logger Events can the D8112G2 store?
Solution
The D8112G2 Control Communicator can store up to 400 Events in the panel memory. The panel logs the time, date, event, master zone, and the primary or alternate phone number called for each event. The 400 events can be retrieved with the RAM II, RAM IV or RPS downloading software.
Issue
What are the enviromental considerations for the proper operation of the Bosch control/communicators?
Solution
Indoor Dry.
Relative Humidity 5% to 85% noncondensing at +86 degrees Fahrenheit (+30 degrees Celsius).
Operating temperature would be +32 degrees Fahrenheit to +120 degrees Fahrenheit ( 0 degrees Celsius to 49 degrees Celsius ).
Issue
What voltage and current is the phone line monitor measuring to sense trouble on the phone line on the D7212B/D9112B panels?
Solution
The phone line monitor senses trouble when the voltage on the line falls below 4.5 to 7.5 VDC, or in the off-hook condition when the current is 8 to 13mA.
Issue
How many zones is the D4112 Control Communicator capable of having?
Solution
The D4112 Control Communicator has six end-of-line resisitor supervised, hardwire protective zones. There are five standard programmable zones and one nominal 12 VDC powered zone optimized for two-wire smoke detectors
