The 700 Series conventional smoke detector is an interchangeable head and base detector with a light scattering optical sensor that provides an excellent response to a wide range of fires. The 700 Series consists of two and four wire conventional photoelectric smoke, as well as photoelectric smoke with heat detectors.

Program PGM2 as a 2-Wire Smoke. Wire additional smokes in a similar manner with a 2.2k resistor across the last smoke. Before you begin, be sure that the panel is powered completely down by unplugging its transformer and its backup battery. Also, make sure that the 2-wire smokes you choose to use are compatible with the NEO panel.

Fire Alarm Wiring IDC Circuits Diagram. In the fire alarm industry there are three types of fire alarm wiring circuits. Below is a circuits diagram that displays the circuit styles of an Initiating Device Circuit (IDC). This would be your conventional circuits such as a hard wired panel or the wiring off of an addressable monitor module.

Typical conventional fire alarm system wiring diagram as described below: Firstly you should connect the two wires that are output from the fire alarm control panel to each fire detector, and then at the end of that line connect the end line resistance. But what is the need for the end of line resistance "ELOR"??
Fire Alarm Panel Circuit Diagram
More often, though, hardwired smoke detectors are installed by splicing into a general lighting circuit or outlet circuit. Either a 15-amp circuit (wired with 14-gauge wire) or a 20-amp circuit (wired with 12-gauge cable) is acceptable for powering hardwired smoke detectors. Wiring the smoke detectors is fairly straightforward for an.

The CFP708-2 has 8 AlarmSense zone circuits which are compatible with Apollo's AlarmSense range of detectors & call points AND sounders & visual indicators. (Max. length per circuit is 500m). Call point resistor value. Only use AlarmSense call points. Max. devices per detector zone. 25 AlarmSense detectors/manual call points per AlarmSense zone.
Loop Addressable Fire Alarm System Wiring Diagram Wiring Diagram
Perfect Pair A winning combination Most conventional fire systems require two pairs of wires per zone: one for detection devices such as fire detectors; the other for alarm devices such as sounders.
Fire Alarm Wiring Diagram Schematic
Wire Sizes: The size of the fire alarm wiring depends on the specific application and requirements of the system. Smaller wire sizes, such as 18 AWG, are typically used for power conductors for shorter distances, while larger wire sizes, such as 14 AWG, are used for longer distances.
