Cranford Controls’ family of call points for indoor use has recently been extended with the addition of models optimised for fire, security and process control applications. All versions share a common appearance and offer a number of features designed to speed the installation process and improve usability in service.
The fire system red versions of the new enhanced units are EN54 part 11 compliant, are fitted with a high intensity LED indicator and are supplied ready fitted with 470 Ohm, 680 Ohm resistors and a protective diode, making them compatible with the majority of conventional fire panels on the market. Resistor selection is said to be a userfriendly process during installation.
As standard, every unit is shipped with a re-settable element fitted. A break glass is also supplied, as are two operating keys. Switching from resettable to break glass operation is a simple procedure of replacing one operating element with another.
