Output Circuits
Notification Appliance Circuits
The MS-4424 can provide four Notification Appliance Circuits (two Style Y/Z and two Style Y only). Each
circuit is capable of providing up to 1.5 amps of current. Total current drawn from all four circuits and the
unregulated power cannot exceed 2.25 amps. Refer to the Device Compatibility Chart for suitable devices.
Circuits are supervised and power-limited.
Ring-by-Zone Feature
Outputs will function as General Alarm (all four outputs will be activated when any zone goes into alarm)
unless the jumpers marked GEN ALM1, GEN ALM2 and SUPV1 are cut. DO NOT CUT the SUPV2
jumper. If these jumpers are cut, the Ring-By-Zone feature is enabled.
Supervisory Appliance Circuit
If Supervisory input is selected (see Section "Dip switch location and Descriptions" ), all four Notification
Appliance Circuits will activate for supervisory conditions (either the SUPV1 or SUPV2 jumper must be
cut). To activate only one Notification Appliance Circuit (Circuit 4), cut SUPV1 jumper. To disable all
Notification Appliance Circuits, cut SUPV2 jumper for supervisory conditions. Refer to Jumper Configu-
ration Table. (See figure below for jumper location).
If a 4XZMF relay module is used, relay 4 will activate for supervisory conditions.
If a RZA-4XF is used, the red LED 4 will annunciate supervisory conditions.
