3M 8900B Series Owner's Manual - System Specifications
System specifications
Electrical requirements
System power input for all systems (RMS)
100-240 V AC 50/60 Hz
Internal consumption
500 mA, 2000 mA output max., 2500 mA max. Total.
Fuse on AC
Schurter FST 5 × 20 mm, Time-lag T, H, 250 V AC, 500 mA
Fuse on DC supply
Schurter SPT, 5 × 20 mm, Time-Lag, T, H, 300 V DC, 2 A
Power cord
18 gauge, 3-wire, S-rating, 9.74 feet [3,0 m] long, NEMA 5-15P plug,
with an IEC 320 connector.
Electrical outlet
Must be within reach of the system power cord.
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.
• Three corridor system, 4 lattices: 100 W.
• Four corridor system, 5 lattices: 125 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.
