Potter SH-120R (part number 4710030) is a wall mount, weatherproof Select-A-Strobe/Horn from the SH-120 Series, with a red housing and clear lens, for 120 VAC operation.
The SH-120 Series provides audible and visual signals for fire and burglar alarm protection systems and notification signals for life safety. It operates on a 120 VAC system between 108 and 132 VAC and can be interfaced with pull stations, flow switches and sprinkler systems in residential, commercial and industrial applications. The horn offers three tones, each as a continuous tone or a temporal (code 3) pattern, and the 90 cd strobe flashes 72 times per minute. A universal pre-wire back plate and single screw mounting simplify installation, and the BBX-5 weatherproof back box is included. Potter notes the SH-120 Series is for general signaling only and is not suitable for occupancy evacuation.
