Sounds like an alarm from an Internet Service Provider box. If so, just unplug the battery and plug it back in to reset it.
Re: Bonding Junction Box If an EGC (not an IG) is pulled and spliced within the box than it must be bonded to the box. If it passes through unbroken than it doesn't require bonding. Trevor, 250.148 states that if there is a splice in the ungrounded conductors, then the EGC .The EMT is the EGC and is bonded to the metal junction box by the EMT .Panel feeds junction box with EMT-From JB to various loads with MC cable. The box . What is the appropriate way to bond a metal junction box containing a receptacle wired with 6 AWG wire? It seems that most metal junction boxes .
The EMT is the EGC and is bonded to the metal junction box by the EMT connector. In a surface mounted the box, many times the next piece is a raised cover or a . If the junction box has metal parts not intended to carry current, you must bond these parts to the grounding system. The grounding conductor must be continuous and .
Often times there is no bonding screw that the equipment ground can wrap around. You also want to make sure that you wrap electrical tape around the receptacle or switch before securing it to. You can install equipment bonding jumpers, bonding jumpers, or bonding conductors inside or outside of a raceway. If inside a raceway, these conductors must be identified per 250.119. If circuit conductors are spliced or .

Panel feeds junction box with EMT-From JB to various loads with MC cable. The box is grounded via the EMT. If over 250 volts and concentric or eccentric KO's are used with . Re: Bonding Junction Box If an EGC (not an IG) is pulled and spliced within the box than it must be bonded to the box. If it passes through unbroken than it doesn't require bonding. Trevor, 250.148 states that if there is a splice in the ungrounded conductors, then the EGC must be bonded to the box. What is the appropriate way to bond a metal junction box containing a receptacle wired with 6 AWG wire? It seems that most metal junction boxes have a 10-32 tapped hole to accept a ground screw but almost all of the pre-built pigtails that . The Standard NFPA 780-2020 gives directions regarding grounding and bonding connections in lightning protection systems. Equipment grounding is the connection to the ground of non-current-carrying conductive materials – e.g., cable trays, metallic conduits, junction boxes, transformer casings, and motor frames.
The EMT is the EGC and is bonded to the metal junction box by the EMT connector. In a surface mounted the box, many times the next piece is a raised cover or a plaster ring, which needs to be bonded to the box. If the junction box has metal parts not intended to carry current, you must bond these parts to the grounding system. The grounding conductor must be continuous and unspliced. It must also be sized according to the size of the junction box.Often times there is no bonding screw that the equipment ground can wrap around. You also want to make sure that you wrap electrical tape around the receptacle or switch before securing it to. You can install equipment bonding jumpers, bonding jumpers, or bonding conductors inside or outside of a raceway. If inside a raceway, these conductors must be identified per 250.119. If circuit conductors are spliced or terminated on equipment within a metal box, then the equipment grounding conductor associated with those circuits must be .

Concentric or eccentric knockouts that are part of a cabinet, cutout box, junction box, or pull box, installed on an electrical system that has a voltage over 250 volts have not been investigated for grounding and bonding, and would therefore .
So while you may not have to connect the equipment grounding conductor to the box, the boxes do have to be grounded and bonded. Since you're using EMT, the boxes can be grounded and bonded via the conduit. If you were using nonmetallic conduit, you'd have to ground the boxes some how.

types of junction boxes
The simple answer is that they are using near IR. LED manufacturers have a good handle on how to make them so they are affordable. Their center frequencies may be invisible to the M-1 eyeball (i.e. human eye), but unless they put a filter in front of the LEDs (which cause them to produce less illumination) there will be some of it that you can see.
