Datasheets

The PF-IS range includes Ex ia IIC intrinsically safe audible and visual signalling devices, connected via a zener barrier or galvanic isolator and suitable for installation up to Zone 0. The standard versions (A105N, L101L and combination) have a fibre-reinforced ABS enclosure; the mini versions (SM, BM, CM) have a compact polycarbonate enclosure and are also certified for dust (Zone 20) and mining (Group I). The PF-IS-CP4 manual call points have a red painted aluminium enclosure with break glass.
