Section 7: Control Modules
7.1 Description
The M300CJ module is an addressable module that can be used for monitoring and switching 24
VDC Notification Appliance Circuit (NAC) power for NFPA Style Y (Class B) and NFPA Style Z
(Class A) circuits. It can also be used for audio/voice applications and fire-fighters telephone; these
two types of applications are documented separately. For UL 9th edition audio applications, refer to
the
Digital Voice Command Manual
and the
Digital Audio Amplifiers Manual
. For UL 8th edition
audio applications, refer to the
Voice Alarm System Manual
or
FireVoice 25/50 Manual.
The
module has a resistor on the back (refer to Figure 7.2) that must be removed when it is used on an
FFT-7 or FFT-7S telephone circuit.
The M300CJ-REL is an addressable module used to switch an external power supply to a solenoid.
The M300CJ-REL can be configured for NFPA Class B or Class A wiring. When using the
M300CJ-REL for Class B applications, remove jumper J1 (refer to Figure 7.4) on the back.
Refer to the
Device Compatibility Document
for a list of compatible UL Listed Fire Alarm
Releasing Solenoids. For more information on the module specifications refer to the
Installation
Instructions
provided with these devices.
Setting an SLC Address
Each module is factory preset with an address of “00.” To set an SLC address refer to “Setting SLC
Address on Module” on page 35.
