12.1 Important battery information
Battery information relating to power consumption and batteries (Art. No. 805597) for use in IQ8Wireless RF
components
•
Insert batteries into the RF devices shortly before initial operation (assigned to the RF transponders)!
Unassigned RF devices consume approx. 4 times more power.
•
Bear in mind the sufficient remaining field strength!
Operation with low field strength causes the power consumption to be somewhat higher. Similar RF devices
which were put into operation at the same time may subsequently register low battery voltage (batt. < 30) on
the FACP after different running times.
The probability of interferences (e.g. caused by electromagnetic pollution or alternating field strength) rises
very high relating to the reduced field strength. If the wireless transmission is interrupted and a wireless
devices must leave the frequency hopping mode, it is operated in the basic channels until the assigned
transponder is able to take this device into the frequency hopping mode again. In this mode the current
consumption may increase up to 4 times higher.
•
How often a RF transponder has to search for one of its RF devices in the base channel can be determined
using the Service PC on the >disturbance< counter in the programming software tools 8000.
•
If the 12/24 V DC power supply to a RF transponder should malfunction, the radio operation of the
transponder terminates and all the assigned RF devices search in the base channel for this RF transponder.
This causes the RF devices' power consumption to be up to approx. 4 times higher.
•
In the case of an alarm, the detectors in the RF devices consume somewhat more power.
•
In an uncharged state, the approved batteries (Art. No. 805597) have a very low self-discharge rate
(1 % annually @ 25°C ± 10°C). Storage outside this temperature range causes the self-discharge rate to
increase. The nominal capacity of the batteries decreases, for example, at low temperatures and is
20-30 % lower during operation near to the freezing point.
•
Due to "passivation effects" batteries which are more than 3 years old should no longer be used. Batteries
are labelled accordingly.
Code 1 (e.g. F.02.277.E)
F = France
02 = produced year
277 = produced day 277th day
E = charge
or Code 2 (e.g. 05 049 A 066)
05 = produced year
049 = produced day
A 066 = charge
•
For initial operation, the batteries are inserted and then charged automatically for a short time and with a
very high current. In rare cases, this may cause low battery voltage
(batt. < 30) to be immediately displayed on the FACP.
Remedy: Activate the RF devices once more using the FACP.
•
For functioning devices, the battery voltage is checked approx. every 12 hours automatically and approx. 2
minutes after insertion of the batteries/after activation (detector zone/detector) of a RF device.
•
Do not touch the battery poles or contacts of the RF devices with bare fingers! A layer of grease causes
transfer resistance to build up between the batteries and contacts. This transfer resistance may lead to the
FACP prematurely or incorrectly displaying low battery voltage (batt. < 30).
•
Improper storage of the RF devices and batteries may be the cause of such transfer resistance (e.g. due to
corrosion). If necessary, clean contacts before inserting the batteries (e.g. with isopropanol solution).
•
Only change the batteries as a set (4 items) in order to ensure an equal charge. The registered low battery
voltage (batt. < 30) on the FACP always relates to the battery with the smallest capacity.
•
For RF devices which register low battery voltage after a long operating time, the malfunction may be
repaired during inspection by agitating the batteries used for a short amount of time (a few hours). When the
RF device is activated, no "low battery voltage" message appears. Completely replace the set of batteries
for the corresponding RF device!
