Product Description Circuits
• Amplifier Supervision (green) - Amplifier module
1.4 Circuits
Input Circuits - CMD1, CMD2, CMD3, CMD4 & CMD5
• Input circuits CMD1 and CMD2 are independently field programmable to accept Notification
Appliance Circuits or normally open contacts.
( IMPORTANT! When CMD1 and CMD2 are
configured for reverse polarity, the NAC cannot be Coded). Terminals are provided to allow
feed-through of the NACs, allowing placement of the ACC-25/50 Series anywhere along a
Notification Appliance Circuit. A trouble on the ACC-25/50 Series will cause relay contacts at
the out terminals of CMD1 to open, causing an NAC circuit trouble at the FACP.
• Programming CMD1 and/or CMD2 for activation on contact closure will allow activation of
the amplifiers on a normally open contact transfer to the closed condition. Contact wiring is
supervised for open conditions. A short will cause amplifier activation (contact closure).
• Input circuits CMD3, CMD4 and CMD5 will only activate on contact closure which will allow
activation of the amplifiers on a normally open contact transfer to the closed condition.
Contact wiring is supervised for open conditions.
Audio Input Jacks
• RCA Jack provides convenient connection to an audio source such as a tape player for
recording a new digital message. It may also be used for background music if approved by
local AHJ. Background music is prohibited during AC loss conditions to preserve battery
power.
• PC Jack provides convenient connection to an audio source such as a personal computer for
recording a new digital message. The jack allows vertical plug-in of a standard mini-jack
cable. It may also be used for background music if approved by local AHJ. Background music
is prohibited during AC loss conditions to preserve battery power.
Output Circuits
• Specific Application Power Output, 35 mA @ 24 VDC.
• Main circuit provides a 24 Volt Battery Charger (up to 18 AH batteries) @ 800 mA maximum.
Master Command Output Bus
• Normal Operating Voltage: 24 VDC regulated, filtered. Reverse Polarity Current 120 mA
maximum
• Output reverses polarity on activation
• All-Call Paging control bus for the Audio Command Center Distributed Audio panel (ACC-
25/50DA) or other Fire•Lite UL-listed audio products
Notification Appliance Circuit
• One NAC Speaker Circuit Style Y or Style Z with each ACC-AAM25 amplifier module.
• Four NAC Speaker Circuits Style Z or eight Style Y with ACC-ZSM (ACC-25/50ZS/T only)
Relays
• One Form-C Trouble Relay. Contacts are rated 2.0 amps @ 30 VDC (resistive) and 0.6 amps
@ 30 VAC (resistive)
NOTE: The ACC-25/50 Series will not open the out terminals while in alarm or during AC loss if
the Trouble Relay is programmed not to transfer on AC Loss conditions (refer to Switch 8 in Table
2.3 on page 34). Monitoring ACC-25/50 Series troubles while in alarm requires use of
independent trouble relay at TB1.
