OPTIONS:
AUX +24VDC OUTPUT - TB2-4, 8, 9 & 10
These terminals provide a max. 200 mA of regulated 24VDC power for auxiliary functions. Do not exceed 200 mA load combined
on these terminals. For connection to Listed General Signal devices only (Non-Fire Protective Signaling applications). Terminal 4
activation is programmed in the system conguration. Standard conguration is programmed for TB2-4 to go active +24VDC under
these conditions: Aux Signal Active, Aux Audio Enable and Bell Circuit Active.
CONNECTION OF AN AUX AUDIO SOURCE - TB2-1 & 2
An aux audio source from additional paging equipment may be connected to the EVAX 25 / 50 / 100 to augment an existing paging
system. It is not intended for continuous signal input, but may be used for paging applications. For such an operation the Aux Audio
Enable input, TB2-6, must be powered from Int V+, TB2-9. This is to ensure that in the event of an alarm, the aux audio will not
override the evacuation signal. See Wiring Diagram 5 for connection detail.
OPTIONAL SUPERVISORY CIRCUIT - TB3-1 & 2
In place of normal supervision via the signaling circuit, an alternate method may be employed using any supervisory circuit from the
FACP. Connection would be made to Terminal Block 3, Ter. 1 and 2. This would provide a normally closed connection to the EOLR
on Ter. 3 and 4. The relay contact in the circuit will open upon any trouble condition and report an open circuit trouble to the FACP.
NOTE: Jumper shorting blocks A and B must be removed from J1 if a circuit is to be connected in this manner. See Optional
Supervisory Circuit Application (Wiring Diagram 2) for connection detail.
OPERATION
In normal standby the Green LED will remain on.
In alarm condition the Red LED will remain on as long as the unit is in alarm. Green LED will modulate with the audio level.
Default Factory Alarm Sequence settings: (Alarm Tone - 2 cycles Temporal Whoop, Message On - 3 Repeats)
Alarm Tone / Digital Message plays / Alarm Tone / Digital Message plays / Alarm Tone / Digital Message plays / unit reverts to
Alarm Tone until alarm condition is cleared. If the Mic is keyed it will override both the tone and the message so a direct broadcast
may be made. If this occurs during the initial sequence the digital message will be reset and will not repeat. When the Mic is keyed
or when the message is played the Green LED will dim. The intensity of the Green LED will vary with the level of the broadcast
audio. Under a fault condition, the Yellow LED will remain on. The Green LED will ash. The number of ashes display a code
depending on the specic type of fault. When there is a fault condition the contact connecting the FACP signal circuit to the
EOLR will open indicating the fault to the panel which will provide annunciation. During a ground fault condition, Yellow LED 4 will
illuminate.
