Simplex 4100U Installation & Maintenance

11-3
All the 4100U cards and modules (pcbs) are tested and aligned in the factory before being
supplied to the customer or fitted to a FIP. The only field adjustment that may be
necessary is to set the battery charger voltage. (Note this has been set and should not
need re-adjusting).
R341 Battery Charger Voltage
Should the battery charger voltage need adjusting, the method is as follows:
1. Run the system with the batteries connected and the door closed for at least 30
minutes to allow components to "warm up" (the longer the better).
2. Calculate the required no-load battery charging voltage by taking 27.3V for
20°C and subtracting approximately 0.1V for every 3°C above 20°C, or adding
approximately 0.1V for every 3°C below 20°C.
3. With the system not in Alarm, disconnect the batteries.
4. Measure the voltage at the battery terminals and adjust to the voltage calculated
in Step 2 by turning pot R341.
5. Re-connect the batteries.
