Explosion Interface
I-9333EX
Features and Benefits
1. Interface for Intrinsically safe sounder
and sounder strobe
2. Electronically addressed
3. Microprocessor supervises running status
and gives diagnosis message.
4. With a built-in safety barrier, the
interface can directly match with
intrinsically safe devices.
Description
LD-8333 Interface can match with explosionproof sounder to form an intrinsically safe
system. When fire occurs, the interface
recieved alarm signal to fire alarm controller
through loop and the controller will give
alarm signal activate the alarm. When the
interface itself is in fault, the controller will
give fault signal and display the fault address
of the interface.
Electronic addressing can be done through
Handheld Programming tool (P-9910),
purchased separately.
