FC421CP-I Outdoor Weatherproof Resettable
Callpoint
Introduction
The FC421CP-I Weatherproof Addressable
Resettable Callpoint is an outdoor manual callpoint.
The callpoint is designed to monitor and signal
the condition of a switch contact that is operated
by activating the resettable element.
The FC421CP-I is fitted onto a standard KAC
weatherproof backbox, which is supplied with
the callpoint.
The
FC421CP-I has an integral short-circuit isola-
tor for monitoring the field wiring.
The FC421CP-I callpoint meets the requirements
of EN54 Pt. 11 and EN54 Pt. 17.
