Next from the top of programming you will need to go to the zone type programming section for your 4-wire smoke zones: Section 001 (Zones 1-16), Section 002 (Zones 17-24), etc. Sensor reset does this when you activate the output by entering *72 on the keypad. This means that once they detect smoke they will stay in an alarm state until the power is turned off to them and then turned back on. The reason you will want to set the PGM that your 4-wire smoke detectors are connected to to sensor reset is because the smoke detectors are latching. If you used a different PGM you will need to go to that PGM and enter 03. Next for PGM 2 you will enter 03 to set PGM 2 as sensor reset. Again, you will just re-enter the first two digits for PGM 1 or enter 00 if not being used. Assuming you used PGM 2, enter into section 009 as you did with the 2-wire smokes. You will go into panel programming by entering *8 + 4-digit Installer Code. The programming for 4-wire smoke detectors is also a little more complicated. The last 4-wire smoke detector on each zone will need a 5.6K ohm resistor wired across the NO and C terminals. This is a big benefit to 4-wire smokes because you can know which smoke detector or detectors are going off or at least potentially narrow it down more than 2-wire smokes. If you have a third 4-wire smoke detector you can make the same choice and so on. The power wires can also be home run to the PGM and Aux +. Or you can wire the alarm circuit to a different zone. You can wire second one in parallel to your first smoke detector: + to +, - to -, NO to NO, and C to C.
If you have multiple 4-wire smokes you have a couple options on how to wire them. These terminals will wire to a zone terminal and corresponding COM terminal on your main board or PC5108 zone expander. The NO and C terminals will be for your alarm circuit. Those 2 wires will be your power circuit. It is common to use PGM 2 here as it gives you a greater current draw than PGM 1, but it is not required to use a particular PGM. The - terminal will wire to a PGM terminal. On your first 4-wire smoke detector you will wire the + terminal to Aux + on the main board. Besides the + terminal(s) you will have -, NO (normally open), and C or COM (common).
You may see more, but it is common for there to be 2 terminals labeled +. You should see 4 unique terminals on the smoke detectors. The wiring for the 4-wire smokes is very similar in some ways, but with the actual alarm initiating circuit separated out. That is all there is to 2-wire smoke detector programming. You can then press # to exit programming. You can leave these the same or program them as needed or if you are not using PGM 1 you can enter 00. For your 2-wire smoke programming you will need to get to the second PGM since that is where is connected. We suggest spending the money and getting an alphanumeric to save some headaches, but it is not required.) Enter into the keypad 009 and that will take you into Section 009 which is PGM programming. (If you’re not using an alpha-numeric keypad then you won’t see much else but lights. You will then see ‘Enter Section’ if you’re using an alpha-numeric keypad. The third would wire to the second in the same fashion and so on. On the last 2-wire smoke detector in your line you will put the 2.2k ohm resistor that came with your main board across the + and - terminals.Īfter hooking in your wires from the 2-wire smoke run you will need to go into programming by entering *8 + 4-digit Installer Code. This means that you will wire the second smoke detector to the first connecting + terminal to + terminal and connecting - terminal to - terminal. If you have more than one 2-wire smoke detector, you will need to connect subsequent smoke detectors in parallel.
You will then take the positive wire from your first smoke detector and wire it into the AUX+ terminal on the main board. It must go to the PGM 2 terminal and not any other PGM terminal for 2-wire smoke detectors. You will first take the negative wire from your first smoke detector and wire it into the PGM 2 terminal on the main DSC control board. Wiring a 2-wire smoke to a DSC 1616, 1832, or 1864 is the easier of the two so we will start there. We will try to simplify things for you to make the process as smooth as possible. While wiring and programming smoke detectors is relatively simple, it can be kind of confusing at first glance.
