PCB0210A by carefully sliding X4A and X4B onto the receptacles on the printed circuit board Er SYSTEM WIRING The placing of emergency strobes into daisy chains is a simple matter of connecting the strobes together with a suitable two wire or single pair cable This cable must be of sufficiently low resistance to ensure that voltage drop along the cable does not violate the minimum input voltage specification of the emergency strobe 8 0 volts Austdac recommends that 2 5mm cable be used for most installations as it provides a good resistance strength and cost trade off The control signal can be derived from any suitable power source with a maximum voltage of 27 0 volts This power source can be an industrial power supply an explosion protected power supply or a zener barrier depending on the regulations and legislation applicable in the country of installation MSHA approval restricts the power source to a nominal 12 volts and only allows the power supply types listed in table 3 The MSHA approved power supplies must be located in a safe area or an MSHA approved flameproof enclosure Wiring from the power to the strobes and between the strobes must be of a MSHA approved type as listed in table 4 Normal installation codes of practice provisions apply in all other countries A system description document should also be done in accordance with IEC60079 25 in these other jurisdictions MSHA APPROVED POWER SUPPLIES FOR USE WITH EMERGENCY STR
