System specifications

Electrical requirements

System power input for all systems (RMS)
Internal consumption
Fuse on AC
Fuse on DC supply
Power cord
Electrical outlet
Maximum power requirements per lattice is 25 W. Maximum system power requirements:
• One corridor system, 2 lattices: 50 W.
• Two corridor system, 3 lattices: 75 W.
A dedicated circuit is not required but is recommended to prevent overloading and loss of security. Circuit loading must not exceed
50% of the rated circuit current to help ensure voltage stability.

Options for powering systems

Power entry can be from either side of the detection system as long as the system consists of five or fewer lattices. For larger
systems, power entry must be from both sides.

Options for bringing power to the system

You can supply power to the detection system using any of the following methods:
• Using a wall outlet
• Using a floor outlet next to the system, with the power cord shortened by a certified electrician
• Using an in-floor junction box next to the mounting foot.
