Installation instructions
Warnings
• This product contains components that are sensitive to
static electricity. Failure to follow proper handling
procedures to prevent damage from electrostatic
discharge may result in equipment failure.
• Ensure the 24VDC riser is deenergized before making
cable connections.
To install the 3-REMICA:
FRONT SIDE
The 3-REMICA provides remote paging capability at stations
located throughout a building or campus. The 3-REMICA can
be connected to other remote microphone units to provide up
to 63 stations on the paging circuit.
The 3-REMICA occupies 2 slot positions in a 2-space, 6-space
or 10-space remote annunciator cabinet. When installed in a
cabinet with an annunciator controller, the 3-REMICA must
occupy the slot positions next to the controller.
The 3-REMICA housing assembly provides standoffs for
mounting a Signature single input module when the system
application requires electrical supervision. The 3-REMICA
trouble relay contacts change state whenever an electrical
short or open is detected on either the microphone or audio
inputs, or whenever power is interrupted to the unit.
