What are the enviromental considerations for the proper operation of the Bosch control/communicators?
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 ).
How can a SKED be disabled or changed?
Overview: Keypad displays a flashing "service perimeter" because a zone is or was faulted.
Keypad displays a flashing "Service Perimeter" with no zones displayed.
A Perimeter zone is or was faulted.
If a zone is displayed, the zone must be made normal first.
If no zone is displayed, enter CODE + ENTER + CLEAR + CLEAR . This will clear the keypad memory.
Why would the keypad display Not Ready, but no zone number is displayed?
An invisible zone is not ready.
Enter a valid pin number + off to display the zone number of the invisible zone that is not ready.

When do the D7112 Transmitters send a Low Battery Report?
For the Transmitters that use the 3.6V Lithium battery (D7121, D7122, D7130, D7131, D7198, and D7199), the low battery threshold is 3.4V.
For the transmitters that use the 9V Alkaline battery (D7190, D7191), the low battery threshold is 7.2V.
How many 2 wire smokes will the D7112 support on zone 1?
Manufacturer & Models, and the number of smokes
Radionics D262 with the D260 base = 20 smokes
DS200 with the MB200-2w base = 10 smokes
System Sensor 1400 = 10 smokes
System Sensor 2400 = 10 smokes
System Sensor 2400TH = 10 smokes
System Sensor 1451 with the B401 base = 10 smokes
System Sensor 1451 DH with the DH400 base = 10 smokes
System Sensor 2451 with the B401,B401B or DH400 = 10 smokes
System Sensor 2451TH with the B401,B401B or DH400 = 10 smokes
System Sensor 2300T = 10 smokes
Setting up the duress code on the DS7400XI 3+.
1. Enter the program mode
A. At the master keypad, enter the programmers code + #0. Ie...9876#0
Keypad should display:
Prog.mode, the version and adr =
2. Enter a (2) digit report code in address 0322. Ie...032210#; this would be an example of a valid entry for the contact id mode.
3. Exit program mode
A. At the keypad press and hold the star(*) key for 3 seconds and release it. You now should be out of the program mode, keypad should not display prog. mode anymore.
4. Assign the duress code to an available user #.
A. At the keypad enter a master code followed by #0. Keypad now should scroll through an options menu.
B. Press 0 then follow the instructions on the keypad. A duress code is authority level 5.
Test the duress.
The system should be armed and the exit delay time expired when disarming with the duress.
