D7212GV2 | Operation and Installation Guide | 5.0 Power Supply . 5. 5.0 Power Supply 5.1 Primary Power Terminals 1 and 2 5.1.1 Primary (AC) Power Circuit The primary source is a 16.5 VAC, 40 VA, internallyfused transformer (Bosch Security Systems, Inc. Model D1640). The control panel draws 200 mA when idle and 500 mA when in an alarm state. The total available auxiliary current is 1.4 A. Transient suppressors and spark gaps protect the circuit from power surges.
PAGE 22
D7212GV2 | Operation and Installation Guide | 5.0 4. Power Supply Connect the red battery lead to Terminal 5, and then to the positive (+) side of the battery. Caution: The battery terminals and wire are not power limited. A 6.4 mm (0.250 in.) space must be maintained between the battery terminals, battery wiring, and all other wiring. Battery wiring cannot share the same conduit, conduit fittings, or conduit knockouts with other wiring. Refer to Figure 8. Warning: High current arcs are possible.

D7212GV2 | Operation and Installation Guide | 5.0 . 5.2.3 Replacing the Battery Figure 9: Power Supply Charging and Battery LEDs Replace batteries every 3 to 5 years under normal use. Record the date of installation directly on the battery. Caution: Exceeding the maximum output ratings or installing the transformer in an outlet that is routinely switched off causes heavy discharges. Routine heavy discharges can lead to premature battery failure.
PAGE 24
D7212GV2 | Operation and Installation Guide | 5.0 Power Supply A shorted battery condition is created either by a shorted cell inside the battery or by a short on Terminals 4 and 5. A shorted battery might cause the control panel to operate in an unsafe way. This condition generates WATCHDOG RESET reports. 5.2.6 Battery Discharge and Recharge Schedule Table 7: Battery Discharge and Recharge Schedule Discharge Cycle AC Off: 13.9 VDC: 13.8 VDC: 12.0 VDC: < 10.0 VDC: Recharge Cycle AC On: 13.

D7212GV2 | Operation and Installation Guide | 8.0 On-Board Points . 8.0 On-Board Points 8.1 Terminals 11 to 22 Description The control panel provides eight on-board points. Each point functions independently and does not interfere with the operation of the others. The control panel monitors the sensor loops for normal, shorted, or open conditions between an input terminal (11, 13, 14, 16, 17, 19, 20, or 22) and any of the point common terminals (12, 15, 18, and 21).
PAGE 30
D7212GV2 | Operation and Installation Guide | 8.0 8.4 Point Response Time On-Board Points 8.5 The control panel scans on-board and off-board point sensor loops every 300 ms. The Debounce program item in the Point Assignment section of the software determines point response time by setting the number of times the control panel scans a point before generating an alarm. The debounce count can range from 2 to 15; therefore, point response time ranges from 600 ms to 4.5 sec. The Bosch Security Systems, Inc.
