Product Description
Specifications
End-of-Line Resistor required for Class B using Terminals 1(+) & 4(-): 4.7 K
, ½ watt
(P/N: 27072)
Class A (no End-of-Line Resistor) requires the wiring of Terminal 1(+) to 2(+) and Terminal
3(-) to 4(-)
Up to 25 Distributed Audio Panels may be connected to this output (ACC-25/50 Only)
Special Application Power (Aux. Power) - TB4 Terminals 1(+) & 2(-)
Up to 35 mA @ 24 VDC of special application power is available for powering addressable mod-
ules and associated End-of-Line power supervision relays.
Power-limited circuitry. Refer to the Device Compatibility Document for a list of compatible
devices.
Form-C Trouble Relay - TB1
Normally energized fail-safe relay can be programmed to transfer its contacts on any panel trouble
condition or on any trouble condition
except
AC Loss (see Table 2.3 on page 34).
TB1 Form-C relay contact rating: 2.0 amps @ 30 VDC (resistive), 0.6 amps @ 30 VAC (resistive).
External Audio Input
• RCA Audio Jack Input (female connector)
nput Impedance: 30K
maximum
Input Voltage: 700 mV
RMS
maximum
Input Current: 1 mA maximum @ 700 mV
Requires preamplifier output. Mates to an RCA phono 'plug' - 3mm diameter, 10mm
length, 9mm shell diameter.

Interfaces to personal computer line output
FC-MIM Microphone Interface Module
(Optional)
- P5 Connector
Connector P5 provides a connection for:
• the optional FC-MIM Microphone Interface Module which is used to connect the FC-RM
Remote Microphone Module to provide remote microphone paging capabilities.
• the ACC-FFT Fire Fighter Telephone module which is used for emergency telephone appli-
cations.
Microphone connector for Fire•Lite standard microphone P/N:45025 - P6 Connector
ACC-EPM External Page Module (
Optional
)
Audio Input Impedance: 600
maximum
Audio Input Voltage: 700 mV
RMS
maximum
Audio Input Current: 1 mA maximum @ 700 mV
Contact Closure Operation Current: 2.3 mA maximum
External paging equipment is electrically isolated from ACC-25/50, ACC-25/50ZS and ACC-
25/50ZST
NOTE:
Some laptop personal computers only provide an audio output for headphones. It may
be necessary to adjust the headphone output level for proper recording of voice messages.
NOTE:
For systems that require both the Remote Microphone and Fire Fighter Telephone, the
ACC-FFT is connected to the P5 connector on the main circuit board and the Remote Microphone
connections are made on the ACC-FFT. The FC-MIM is incorporated into the ACC-FFT Fire
Fighter Telephone Module as part of the ACC-25/50ZST. A separate FC-MIM is therefore not
required for this system.
