Lithium Batteries - DSC PC4020 Installation Manual

3. On the chart below, find the standby current on the hori-
zontal axis and the alarm current on the vertical axis.
4. Find the region of the chart where the standby current
and the alarm current values intersect. The region corre-
sponds to the required battery Ah capacity.
For example:
Standby current = 500 mA
Alarm current = 2 A
On the 24Hr chart, the battery capacity required is 14Ah

2.15 Lithium Batteries

The PC4020 circuit board includes a lithium battery (please
see the wiring diagram on page ii.) This battery is not
replaceable. There is a danger of explosion if the battery is
incorrectly replaced.
If the lithium battery stops working, return the circuit board
to your distributor. Batteries may cause a fire when in con-
tact with metal. If you need to dispose of the circuit board
and/or the lithium battery, wrap the battery in non-conduc-
tive tape. Check with your local government for battery dis-
posal regulations.
WARNING: Do not store the batteries in such a way that
they come into contact with each other or with any piece of
metal. Explosion or fire may occur. Should fire occur, use
only dry chemical fire extinguishers. Do not use water to
put out the fire.
Do not heat the batteries. Do not dispose of the batteries
or circuit boards in a fire. Do not disassemble the batteries.
Do not apply pressure to or deform the batteries. Ensure
that the above precautions are strictly observed by related
departments, including, but not limited to, production,
sales and outside contractors.
