7.1 3-30 95-8533
Supervised Output—
Notification Supervised for Open & Short Circuits
Connect external system wiring to the appropriate
terminals on the terminal block. For Class B, Style Y
wiring, refer to Figure 3-34.
For Class A, Style Z wiring, refer to Figure 3-35. Note
that two channels are used for one output circuit.
The output of the EDIO module supervises the
notification circuit by reversing the polarity of the
monitoring circuit. Polarity must be observed when
connecting the notification device. It is essential to
utilize a notification device approved for fire alarm
notification. These devices are polarized and would
not require the use of an external diode for the
supervision of the circuit. Wire one or more notification
devices to the output, with a 10 K ohm, 1/4 watt EOL
resistor in parallel across the last device.
No connection should be made to “+ Supply”
terminal.
Each output channel is individually activated for
response pattern:
– supervisory
– continuous output
– 60 beats per minute
– 120 beats per minute
– temporal
– timed
– trouble.
Supervised Output—
Agent Release (Solenoid Circuit)
Connect external system wiring to the appropriate
terminals on the terminal block. For Class B wiring,
refer to Figure 3-36.
For Class A wiring, refer to Figure 3-37. Note that two
channels are used for one output circuit. Trouble
indication is provided for any open wire and the
output can still be activated with a single open wire.
Wire one or more releasing devices to the module
output.
No connection should be made to “+ Supply”
terminal.
The output of the EDIO module supervises the
releasing circuit via the coil of the releasing solenoid.
It is essential to utilize a releasing device approved for
use with this output module. This type of output does
not require the use of EOL resistors or diodes to
supervise the circuit.
