Output Circuits
DC Power Output Connections
All DC power outputs are power-limited.
Telephone Circuits
Provision to connect to two independent telephone lines is available via two telephone jacks labeled PH1 (primary)
and PH2 (secondary). Telephone line control/command is possible via double line seizure as well as usage of an
RJ31X style interconnection. Refer to Figure 2-10, “Wiring Phone Jacks,” on page 27.
Notification Appliance Circuits
The MS-5024UD provides two NACs (Notification Appliance Circuits) which can be configured as Style Y or Style
Z. Each circuit is capable of 2.5 amps of current. Total current drawn from these as will as other DC power outputs
cannot exceed 3.6 amps with the standard transformer, 5.6 amps if an optional XRM-24 transformer (XRM-24E for
the MS-5024UDE) is installed. Circuits are supervised and power-limited. Refer to the Fire•Lite Device Compatibil-
ity Document for a listing of compatible notification appliances.
Both Notification Appliance Circuits may be programmed as follows:
• Silenceable
• Nonsilenceable
• Enabled/disabled
• Silence inhibited
• Autosilence, 5 to 30 minutes
• Coded (March Time, Temporal or California)
