Compatibility
Designed to comply with the requirements of BS5839-4 (for head-out monitoring use 1 x BF378M module per zone).
Mains supply
230V 50/60Hz.Mains rated current700mA max.
Internal power supply27V nominal.
Total output current limited to3A @ 230V.Quiescent current70mA (with no mains supply, fault beeper muted, no aux. output connections, EOL devices and resistors only fitted to detector and sounder loops).
