Chapter 5. Electrical Power Connection and Interfacing

All power supplies must be hard wired and must include a circuit breaker (RCD / RCCB), and (close by and

Lethal current may be present in this equipment when electrical power is applied. There is a danger of death or
injury from electrical shock. Isolate power before opening electrical access panels. Ensure residual current is fully
Lethal current may be generated both internally and externally to the system. All installations, including remote
units and cables, must be connected to protective earth, and must be capable of remaining so when the power
Honeywell can accept no responsibility for any damage or injury caused by incorrect or faulty wiring.
It is the customer's responsibility to provide appropriate power supplies to the TPPL and detectors.
5.1 Power Connection
Every TPPL Controller and Expansion Unit is factory set to operate at a manually switchable voltage of AC 110/220 V on
single phase, 50 to 60 Hz power supplies. They can also be connected to DC 18 – 32 V SELV supplies with their backup
battery removed, or DC 24 – 32 V SELV supplies with a battery fitted (24 V is the battery's minimum charging current).
TPPL Controller and Expansion Units each have a typical peak power consumption of less than 105 W, and they must be
directly connected to power supplies via a Main Isolator Switch that leaves protective earth (ground) permanently
connected. The circuit should incorporate a Residual Current Device (RCD) or Residual Current Circuit Breaker (RCCB).
TPPL systems are not certified for connection to domestic or fluctuating power supplies.
The system is normally supplied with the voltage pre-set to the customer's specification. Before connecting to
Mains Power check the SMPS voltage setting and correct as necessary. Remove the yellow label when done.
