Notes
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 Vdc, and with the mains off it provides
battery voltage.
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 & external devices.
4 Battery charging can be set to 1.4 Amps or 0.9 Amps, depending upon the size of
battery. However, because the battery charger runs at a higher voltage, its power
consumption is higher. The equivalent current consumption in user terms is therefore
2.0 or 1.3 Amps respectively.
5 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.
6 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.
