BExCP3-PB Push Button Manual Call Point

The BExCP3-PB push button manual call points are designed for the harshest of environments and approved for Zone 1, 2, 21 and 22 explosion proof hazardous areas for the control of fire and gas alarm systems. SIL2 compliant to IEC61508 (2010).

The BEx range features enclosures manufactured from corrosion proof, marine grade, copper free LM6 (A413) aluminium with a chromated and powder coat finish. Available with and without monitoring resistors all versions are certified to IECEx and ATEX standards with additional PESO, INMETRO and Ex EAC approvals. The push button mechanism is protected by a spring loaded cover therefore the switch requires a two-action activation. The BExCP3-PB is user re-settable by rotating the push button.
