The suggested <br />pipe configuration is shown to the left. Pipe and fittings <br />are to be supplied by the installer. <br />Low -Pressure Supervisory Switch (P/N 22858) <br />The low-pressure supervisory switch continuously moni- <br />tors the pressure of the cylinder. The contact configu- <br />ration is single pole, single throw (SPST) with contacts <br />rated 1.5 Amps at 24 VDC. Should the cylinder pressure <br />drop to approximately 440 psi (30.3 bar), the switch con- <br />tacts will close transmitting a signal to the system control <br />panel. It is mounted to the cylinder valve and cannot be <br />replaced while under pressure. <br />Pressure Gauge (P/N 22942) <br />NFPA2001 mandates a pressure gauge for each cylinder <br />as a method of visually monitoring the internal pressure <br />condition of the cylinder assembly. The pressure gauge <br />is mounted to the cylinder valve and cannot be replaced <br />while under pressure. <br />DS1258 Revised: 21-Dec-2023 <br />Page 4 of 10 <br />
