Alarm Line Sign | 6 in. x 2 in.

Alarm Line Sign is an NFPA 13-compliant white powder-coated 18-gauge aluminum (.040 aluminum) sign designed to indicate the presence of an alarm line to facility managers, building occupants, and fire professionals. This 6 in. (152.4 mm) x 2 in. (50.8 mm) sign reads 'Alarm Line' in red letters at least one inch (25.4 mm) in height.

NFPA 13 alarm lines are connected to trim piping. When fire sprinklers activate, water enters the alarm line and activates an alarm pressure switch or other device, which indicates that water is flowing in the system. This sign is drilled with four (4) holes for easy hanging.
