Release units can be electric oper- <br />ated only or manual/electric. Depending on the con- <br />trol panel needs, release units can be purchased with <br />pressure gauges using normally open or normally <br />closed contacts (when under pressure). <br />Release units that include manual operation have a tam- <br />per proof seal on the operation pin. Replacement seals <br />are included in the Release Unit Service kit, P/N: 38- <br />400001-010. <br />SPECIFICATIONS <br />Nominal Working Pressure: 300 bar (4350 psi) <br />Max Working Pressure at 50°C (122°F): <br />366 bar (5307 psi) <br />Weight: 1.8 kg (3.97 Ibs) <br />Switch: <br />Voltage; 4.5-24 VDC <br />Current: 5-100mA, Contact Load 2AW max <br />Operating Voltage: 24 VDC 18W <br />Current Draw: 0.75 Amps <br />Gauge: <br />St. St. Casing <br />Accuracy Class 1.6 in <br />Scale: IP 65 <br />Temp Range: <br />FM Approved / UL Listed: -4° to 130°F (-20° to 54°C)* <br />*Unless superseded by local/national standards <br />or Kidde <br />Fire Systems <br />Effective: April 2022 <br />K-38-2110 Rev AD <br />ORDERING INFORMATION <br />Pressure <br />Part Number <br />Operation <br />Contact <br />Rating <br />38-400001-001 <br />200 Bar <br />Manual/ <br />Normally Open <br />Electric <br />38-400001-003 <br />300 Bar <br />Manual/ <br />Normally Open <br />Electric <br />"Not for use on for FM Approved and UL Listed systems, for LPCB <br />Listed systems only <br />
