What it does

Built for open plant areas where water, dust and weather wreak havoc. WMHS-IIWP is a telephone and a page phone in one cast-aluminium housing with an integrated canopy: dial its extension and your voice comes out of its horn; lift the handset and the call goes private. It runs on the SMART MCS-II or any plant EPABX.

01
Built-in 30 W RMS amplifier drives an external 60 W horn
02
Page at that location only; several sets can page at the same time
03
Private conversation the moment the handset is lifted
04
Aluminium alloy casting with integrated canopy, powder coated
05
Encapsulated circuit boards resist water and condensation
06
Magnetic reed hook switch: fewer moving parts to wear
