Panel that can use 2 wire smoke detectors, most houses change owners To “cover our bases”, we use 4-conductor wire, which will handle any possible panel/smoke alarm combination.Įven if we know for sure that a given house will be getting an alarm Homes are prewired by the builder, even with no alarm system in the immediate plans. When a new house gets pre-wired for a security system, we usuallyĭon’t know which specific alarm panel will be installed.

See how to solve this problem at Smoke Detector Wiring - Connecting Multiple Runs. Necessary to pull more than one wire for smokes. Many home alarm systems only provide a single set of terminals for There are several great reasons to choose 4-conductor cable when wiring home smoke detectors. In addition to the various definitions, there are are also attributes that can further customize those PGM types even further.Benefits of Using 4-Conductor Wire with 2 Wire Smoke Detectors

For a full list of PGM definitions check the full installation manual. They can follow the bell output, follow zones, follow keypad chimes, 2-wire smoke zone, resettable power, et cetera. PGM definitions allow for numerous ways that the PGM will function. There are multiple PGM types that may be used for an application like this depending on how you want it to function. The PGM would then trigger the relay to flip to the closed state when an alarm goes off which in turn causes the power circuit to be completed. The relay should be connected in the normally open state so that the power circuit is not closed until the relay flips. The relay will be connected into a circuit with a power supply and the sirens or strobes. Instead the PGM will be connected to a relay. Generally the PGM will not be used to directly power the sirens or strobes in this case. The PGM type that will need to be used with 4-wire smoke detectors is 03 for sensor reset.Īnother common use is to use PGM's to turn on additional sirens or strobes. But you will want to keep in mind the total power draw that you have connected to the PGM to make sure that you are not going to be exceeding it. Any PGM can be used for 4-wire smoke detectors since it is not also the fire zone. So the PGM will only be used for the resettable power source to the 4-wire smoke detectors. With 4-wire smoke detectors the initiating circuit is separate from the power circuit. And PGM 2 must be programmed as PGM type 04. 2-wire smoke detectors must be used with PGM 2 on the main board to function. With 2-wire smoke detectors, the PGM becomes the fire zone for triggering an alarm as well as the resettable power circuit for the devices. There are two kinds of smoke detectors that you can use: 2-wire and 4-wire. So if you ever get a smoke alarm, whether from testing or false alarms or real alarms, you will need to reset the power on the smoke detectors to take them out of their alarm state. This means that they will stay in the alarm state until their power is shut off. The most common use for a PGM is with smoke detectors. There are a few very common uses for a PGM though that we will take a closer look at. In fact, many people will never need to use a PGM output on their system at all. Much of the integration that is possible is really beyond the scope of what the vast majority of people will need and beyond what we will get into. This especially true if you factor in connecting to relays and other power supplies. The possibilities are really pretty much endless. There are 2 modules available that can expand your PGM capabilities: PC5204 and PC5208.Ī PGM can be used for countless applications including custom integrations with things like lights or garage doors. PGM's 1, 3, and 4 all are limited to 50mA each. The PC1616 and PC1832 both have 2 PGM outputs. The most common that you will encounter are the two or four PGM's on the main PowerSeries panel. The other side will generally be on the positive auxiliary power terminal.ĭifferent PGM outputs will have different current draw limits. It is the negative side of the direct current circuit. The system will flip the switch based on what PGM type you program it for. It will be connected to something to provide power that can be turned on or off. What does this mean? You can think of a PGM as an on/off switch like a light switch. So a PGM is a programmable negative trigger output.
