1. Emergency power supply of alarm devices Alarm devices require 2 independent energy sources, both of which must be able to power the alarm device alone. One of the energy sources must be the general mains supply or a similar netwo rk in non-stop operation. The other must be part of the apparatus (e.g. a battery) or an equivalent netw ork fused se[...]

2.3 Fusing the inputs and outputs The batteries have individually fused outputs for the load connections. Thus all plus and minus lines are protected against excess currect and short. Different line cross-sections for consumers wi th low and high current can be connected to a battery at the same time, providing that the fuse values of th eir indivi[...]

Table II shows the maximum currents which can be drawn from the batteries. These must not be e xceeded. This gives the maximum number of power amplifiers which can be powered by the batteries.

2.4. BATTERY CONTROL connection The battery drawers are equipped with a exhaustive discharge protection which is control led by the monitoring module in the charging device DEM 313. The monitoring circuit checks whether the battery’s discharge voltage has been reached when the batteries are discharged. If the battery volta ge is less than 19.5 V,[...]

3.4 Transport If the battery is transported, it should never be exposed to excessive jolting or knocks. If a battery is connected to a device during transport, it must be secured well and the curr ent circuit must be interuppted. 3.5 Battery service life Generally speaking, the battery service life in standy parallel operation amounts to 3 - 5 year[...]

7. Explanation of terms: — Continuous battery power supply In this mode, the battery is constantly kept in full charge. It only gives off current if the DC source, supplied by the mains, fails. — Nominal capacity: The nominal capacity is the value in ampere-hours for a 20-hour even, uninterrupted disc harge with I20 up to the discharge voltage [...]
