This battery is:
• a 12-volt, sealed lead acid type with a nominal power rating
of 2.2 amp-hours
• continuously charged by the Toxgard II Monitor during
normal operation.
Transfer to the backup battery is automatic when main power
loss occurs. While operating on the backup battery, "BATT" lights
on the Toxgard II display. When main power is restored, the
"BATT" turns OFF, and the battery will start to recharge.
The amount of time that the backup battery can operate the
Toxgard II Monitor depends on the:
• type of sensor
• installed options
• presence of alarm conditions
• ambient conditions.
TABLE 1-7 can be used as an approximation of expected battery
operating time. In this table:
• "Minimum Time" represents a Toxgard II Monitor
configured with:
• strobes flashing
• alarm conditions asserted
• Federal horn operational
• internal pump
• "Maximum Time" represents a Toxgard II Monitor
configured with:
• no strobes
• no alarms
• no horn
• no pump.
• Actual battery lifetime falls somewhere between the indicated
Minimum Time and Maximum Time values.
