Use a different pair sets for each type of device you useīut vary these pair sets colours if you use more than one deviceįor passives you need 1 pair for power 1pair for anti tamper 1 pair for 24hr and one pair for alarm closed loop You need 8 core cable for all your stuff even the contactġ} you can use the pair rather than rip the cable out if you get problemsĢ} you can loop 24hr thru the whole alarm making it double safeģ} give people more to do if they decide to munch into a cable and start shorting pairs Then you know what zone was tampered withĢ4hr is userfull for a second loop out thru the alarm sounder and other equipment If you want all the loops on one this is bad. One called 24hr and one called anti tamperįor anti tamper you are right must go off straight offīut usualy there is an antitamper loop for each zone In most alarm panels is two anti tamper loops There is no specific wiring coloring convention, but it is recommended that whatever color convention you use - you stick with it.Can i use 6 core telephone cable for alarm system These devices will typically have the following terminals: Pos (+), Neg (-), COM, NO, and/or NC. It does not matter which wire goes into which terminal.įour-wire devices, such as motion detectors or glass break sensors, have two additional wires to power the sensor.

Two-wire devices, such as door contacts, are wired to an input and COM terminal. Two of the input terminals can share the same common ground terminal (for example Inputs 1 and 2 can share the same COM port, Inputs 3 and 4 will share the same COM, and so on). There are 32 input terminals (numbered 1-32) and 16 common ground terminals (labeled COM). The below table serves to provide a rough guide to the maximum length depending on AWG. Of course, in a real-world application, it will prove difficult to measure end-to-end wire resistance with a sensitivity of 100Ω for existing building wiring. The max line resistance should be less than 100Ω. The best way to ensure valid operation is to measure the resistance of your wire. Ultimately, there are many variables that come into play such as wire gauge, material, solid/stranded, and environmental noise. Recommended Input Wire Gauge for Application These auxiliary terminals are most often used to provide power to motion sensors, glass break sensors, and leak detectors. The max current draw for all AUX outputs combined is 2 amps. The alarm panel also has 6 auxiliary terminals to provide constant 12V DC power. Multiple output devices can be wired in parallel so that activating a single output can turn on several devices simultaneously. When an alarm is raised, the panel supplies power to those outputs.

From Command, users can select outputs to turn on in response to an alarm. The most common output devices are sirens, bells, and strobe lights that are activated when an alarm is raised. The Verkada BP41 has 2x 12V programmable alarm outputs, with a max power draw of 1 amp each. When the panic button is pressed or when there is enough water to complete the circuit in a water sensor, this would be detected as a change from an open to a closed state and trip the alarm. Panic buttons and water sensors are generally wired normally open. When the circuit is open, such as an open door with separated contacts, the panel would detect the change from a closed to an open state and trip the alarm. In most cases, door contact sensors, glass break sensors, and motion sensors are wired normally closed. When you configure an input device, you can specify the normal state as either Normally Open (NO) or Normally Closed (NC). These sensors are typically classified as two-wire and four-wire devices. The Verkada BP41 supports all third-party NO/NC sensor inputs.
