Quite the title I've assembled there and yes, I'm attempting to get all the subject parts to interoperate through relays (if possible).
I've got a stand-alone, precast telecom structure with the subjects that are needing to work together. I'll do my best to best explain how all these will work together along. What I'm asking of the community is help with wiring everything together. If each of these parts worked independently, I'm certain I could get it done; however, they've all got to be connected.
PARTS:
1. (2) Time Delay Relays (Macromatic TE-8812U) - This relay will serve to operate the intake louver, exhaust fan and to also send out two signals for an alarm to an alarm monitoring center.
2. (2) Power Relays (IDEC RH1B-UAZC120V, SPDT) and (2) Relay Bases (IDEC SH1B-05) - These bases and relays will be used in conjunction with the smoke detector and hydrogen detector (1 relay and base for each).
3. (1) Intake Louver (Belimo TFB120)
4. (1) Exhaust Fan (GREENHECK SE1-12-432-A4X)
5. (1) Smoke Detector (GENTEX GN-503FF)
6. (1) Hydrogen Detector (SBS-H2)
7. (1) HVAC Unit (Bard W36A2-A10 3.0 Ton)
8. (1) 66-Pin Alarm Block
9. (2) 20A/1P circuit breakers - (1) for smoke detector, (1) for hydrogen detector
10. (1) 15A/1P circuit breaker - To operate both the intake louver and exhaust fan.
FUNCTIONS:
1. Simultaneously, operated by the time delay relay, the intake louver is to open and the exhaust fan is run once a day for ten minutes to clear the room. When the exhaust fan kicks on, a NO contact alarm is to be sent to the alarm block and clears (back to NC) when the relay turns off. If the time delay relay ever fails, a NO signal is to be sent to the alarm block.
2. In the event either the smoke detector or hydrogen detector go into alarm, the HVAC unit will shutdown. Which ever detector goes into alarm, smoke or hydrogen, a separate signal (opens on alarm) for each will be sent to the alarm block.
3. In the event only the smoke detector goes into alarm, the time delay relay is to be de-energized so the intake louver and exhaust fan do not run, also the HVAC unit will shutdown as well. A smoke alarm signal (opens on alarm) will be sent to the alarm block.
4. In the event only the hydrogen detector goes into alarm, the HVAC unit will shut down, the time delay relay energizes so the intake louver and exhaust fan run simultaneously. A hydrogen alarm signal (opens on alarms) and the exhaust fan timer signal (NO) will be sent to the alarm block.
WHAT I THINK I MIGHT KNOW:
I contacted support at Bard for the HVAC unit. I was told the smoke and hydrogen detectors can be wired in series using (2) separate SPDT relays so that if either detectors goes into an alarm, the HVAC unit will shutdown. The shutdown occurs within the HVAC control wiring; it's just the signal wires (open on alarm) that go back to the unit and breaks the 24V connection.
I'll admit I'm not proficient when it comes to controlling equipment with relays so I cannot even provide a wiring diagram of where I would start. But any help in the right direction would be greatly appreciated.
