This control panel can provide two
Style Z (Class A)/Style Y (Class B)
Notification Appliance Circuits and
two Style Y (Class B) Releasing
Circuits (for DIP switch configu-
ration, see “Setting Mode of
Operation” in Section 2.10). 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 Device
Compatibility Document.
Notification Appliance Circuits are
supervised and power-limited. For
non-silenceable service on NAC#1,
see “Non-Silenceable Service” in
Section 3.8.
Note: Unused Notification
Appliance Circuits must be
connected with a dummy load as
shown.

Output #4 can be configured for releasing or
supervisory circuit (see “Setting Mode of
Operation” in Section 2.10). If configured
as a releasing circuit, the circuit will be non-
power limited. If configured as a super-
visory circuit, the circuit will be power
limited. All wiring must follow the require-
ments as specified under “UL Power-limited
Wiring Requirements” in Section 2.2.
To prevent accidental discharge, connect
releasing devices after initial panel tests are
completed.
Note: Wiring must be configured to maintain a
minimum voltage of 20.4 VDC on release
circuits. Calculation of maximum allowable
resistance:
R
MAX
= 20.6 VDC-20.4 VDC

S
Where:
R
MAX
= maximum allowable resistance of wiring
I
S
= solenoid current
For Canadian applications, use REL-4.7K as
shown.
Note: Unused Releasing Circuits must be wired with a dummy load as shown.
