| The
Low Voltage Alarm detects when the battery voltage drops below a threshold
and remains low for 120 seconds. At that time a relay is operated
which may be connected to the low voltage indicator and alarm. Available
for either 12 or 24 volt electrical systems the unit contains LED
indicators to aid in installation and test. A green indicator is illuminated
whenever the voltage is normal. When the voltage drops below the setpoint
and remains low for 120 seconds the green LED is extinguished and
the red LED is illuminated. The setpoint and time delay meet the requirements
of NFPA 1901, paragraph 9-3.3.
|
| Easily
installed, the Low Voltage Alarm requires only two wires to sense
the battery voltage. The 30 ampere contacts on the relay provide ample
capacity to operate the low voltage alarm and indicator. Availability
of a normally closed contact in addition to the normally open contact
permits a wide variety of connections in the load circuit. |
