Output Circuits

Notification Appliance Circuits

This control panel can provide two Class A (Style Z)/Class B (Style Y) Notification
Appliance Circuits and two Class B (Style Y) Releasing Circuits (see section “Setting
Mode of Operation” for DIP switch configuration). Each circuit is capable of 1.5 amps
of current. Total current drawn from all four circuits cannot exceed 2.25 amps. Refer
to the Compatibility Chart. Circuits are supervised and power-limited.

Note: Wiring must be configured to maintain a minimum voltage of 20.4V on release circuits. Calculation of
maximum allowable resistance:

MAX

= 20.6V-20.4V

________________________________________________________________________

Where: R

MAX

= maximum allowable resistance of wiring

= solenoid current

Note: Output #4 can be configured for releasing or supervisory circuit (see Section “Setting Mode of Opera
configured as a releasing circuit, the circuit will be non-power limited. If configured as a supervisory circuit,
will be power limited. All wiring must follow the power limited “General” Section.
