WIRING AND MOUNTING INFORMATION:
CAUTION:
The following figures (A-D) show the maximum number of field wires (conductors) that can enter the backbox used with each mounting
option. If these limits are exceeded, there may be insufficient space in the backbox to accommodate the field wires and stresses from the wires could
damage the product. Check that the installed product will have sufficient clearance and wiring room prior to installing backboxes and conduit, especially
if sheathed multiconductor cable or 3/4" conduit fittings are used.

AS-MC Appliance has in-out wiring terminals
that accepts two #12 to #18 American Wire Gauge
(AWG) wires at each screw terminal. Strip leads
3/8” inches for connection to screw terminals.
Break all in-out wire runs on supervised
circuit supervision as shown in Figure 6.
The
polarity shown in the wiring diagrams is for the
operation of the appliances.
The polarity is
reversed by the FACP during supervision.
MOUNTING PROCEDURES:
1. This model can be flush mounted to a standard single-gang backbox (Figure A), 4” backbox (Figure B) or double-gang backbox (Figure C). They
can also be surface mounted to a 4” or 100mm backbox (Figure B), a double-gang backbox (Figure C) or a SHBBS surface backbox (Figure D).
Mounting hardware for each mounting option is supplied. For proper mounting, be sure to use the mounting screws su pplied with the unit.
2. The Universal Mounting Plate (UMP) must be oriented correctly when it is mounted to the backbox. Turn the UMP so that the arrow above the
words “Horizontal Strobe” points to the top side of the UMP.
3. Conduit entrances to the backbox should be selected to provide sufficient wiring clearance for the installed product. Do not pass additional wires
(used for other than the signaling appliance) through the backbox. Such additional wires could result in insufficient wiring space for the si gnaling
appliance.
4. When terminating field wires, do not use more lead length than required. Excess lead length could result in insufficient wiring space for the
signaling appliance. Position the field wires in the backbox so that they use minimum space and produce minimum stress on the product. This is
especially important for stiff, heavy gauge wires and wires with thick insulation or sheathing.
5. Thread the 4 field wires through the opening of the UMP. Mount the UMP to backbox.
6. Connect 4 field wires to the AS-MC terminal block (polarity must be observed). Bend the 4 field wires up 90
o
at the connection to the terminal block.
7. Carefully push the 4 field wires into the backbox through the opening of the UMP by hand.
8. Hook the 2 slots on the inside wall of the AS-MC onto the 2 tabs of the UMP and screw the AS-MC to the UMP using the #6-20 screw supplied.
