BF366 24V 5A KEYSWITCH ISOLATABLE RELAY
The BF366 combines the functions of the BF376 relay and BF367 device isolator in one unit. It is double-pole 24V 5A polarised relay with a keyswitch isolation facility allowing its relay operation to be temporarily disabled from the fire alarm signal during routine test and maintenance (to prevent autodiallers, water sprinklers, etc., from activating). Mountable on a 25mm flush or surface UKsingle gang back box, the relay is triggerable via a control panel’s open collector output or a standard polarised sounder circuit. If connecting to a sounder circuit, the relay will return to its normal state when the fire condition is cleared or silenced. Check with the approving authority that the proposed arrangement is acceptable prior to installation.
