outputs can be connected to
each ZP3 panel. These inputs
and outputs can be a mixture of

[1] This is the output voltage available to provide power to auxiliary boards, such as sounder
output boards. It must not be used to power devices not related to the fire system. With the mains
on it is regulated at 24 to 29 VDC, and with the mains off it provides battery voltage, which is
approximately 3 V lower than the battery voltage when a full load (4 A) is connected. As a safety
feature, line device analogue information is ignored by the panel at very low input voltages.
Battery voltages from 19 to 21 V (and lower depending on the current being drawn) cause the
panel to display the message “Fire detection inactive”.
[2] This is the total power supply capability, used for all panel and user operations. The peak
current is only available for short periods of time, not exceeding 30 minutes.
[3] Maximum current used internally by the panel, excluding detectors and external devices.
[4] After deducting panel operation and battery charging requirements, the current remaining is
available for use by external devices such as detectors, accessory boards and sounders. This is
the maximum current available while the system is in a non fire alarm condition.
[5] In a fire alarm condition, the battery charging is disconnected. Therefore, in a fire condition,
additional current is available for external fire alarm devices only, such as sounders.
