1.3 General Description
TKT24 is an addressable 24 V central battery unit (CBU) for emergency lights. The CBU
is supplied with 220–240 AC mains, maintaining the battery charge and supplying the
emergency ligh circuits with 24 VAC. If mains is disconnected, or mains supply drops below the
defined limit, the CBU switches to battery mode, and supplies the emergency ligh circuits with
24 VDC. Battery supply is maintained until the mains is restored (with user set delay), or until
the battery capacity drops to deep discharge limit.
In addition to the mentioned basic functions, the CBU has the following monitoring- and
reporting functions:
• Testing of addressable luminaires, and the monitoring of their operation - indicaties the address of
faulty luminaire
• Tests the batteries automatically
• Tests can also be started manually
• Self-learning system: luminaires can be added or removed after commissioning
• Mode- and warning statuses can be communicated via. relay connections to building monitoring
systems
• A direct data connection to Teknoware ACM system.
• All the functions of the CBU can be accessed from the LCD interface.
1.4 Storage
If the CBU and batteries are not installed directly after delivery, the following instructions must
be followed:
• The CBU must be protected from humidity
• Storing temperature of the CBU and batteries: +10…+30°C.
• If the batteries are stored for an extended period of time, the batteries must be recharged every 6
months, for 12 hours at a time.
Note!
The delivery may include lead batteris, that have charge, and that may short circuit due to
inproper storage! Take this into account when storing the CBU.

Voltage limits
• When mains drops below 165 VAC, the CBU supplies voltage for the emergency lighting from the
batteries
• When mains is disconnected, the CBU supplies voltage for the emergency lighting from the batteries.
• If the battery voltage rises above 28,5 V, the CBU gives a Battery Overvoltage warning
• If the battery voltage drops below 20,0 V:n, the CBU gives a Battery Undervoltage warning.
• During battery mode, if the battery voltage drops below 19,0 V:n, the CBU goes into deep discharge
mode.
