Ease Of Integration | Smoke Detectors | Electrical | Petros
From first tap-in, HEP’s Electrical module slips seamlessly into Petros, letting you deploy, test, and hand over smoke detectors with the same drag-and-drop ease normally reserved for lighting zones or breaker panels. Pre-configured templates recognize every leading device profile, while auto-mapping pinouts and cable runs in real time, so field teams can finish rough-in faster and engineers can validate circuits before a single screw is tightened.
Once online, your detectors join the Petros ecosystem automatically: firmware updates roll out in the background, analytics start benchmarking ambient conditions, and rule-based alerts sync with BMS dashboards, email, or SMS—no middleware, no custom code. The result is a compliant, future-proof life-safety layer that’s as simple to expand as it is to maintain, whether you’re adding one floor or an entire campus.
FAQs
What types of smoke detectors can be integrated with Petros electrical systems?
Petros supports both photo-electric and ionization smoke detectors that use a 24 V DC or 120 V AC power source and provide either a dry-contact relay or a two-wire alarm loop. Detectors certified to UL 268, EN 54-7, or AS 3786 standards are fully compatible, ensuring that common commercial and residential models can be added without the need for proprietary interfaces.
How do I wire a Petros-compatible smoke detector into an existing circuit?
Most installations use the Petros two-wire supervised loop. Run 18-AWG fire-rated cable from the Petros panel to the detector’s positive and negative terminals, observing polarity. For a multi-detector zone, daisy-chain the devices in series and terminate the last unit with the supplied 4.7 kΩ end-of-line resistor. If you are using a 4-wire detector, connect the power pair (typically red/black) to a dedicated Petros auxiliary power output and the alarm relay pair (yellow/blue) to the zone input. Always isolate power before wiring and follow local electrical codes.
Does the Petros smoke-detector integration support interlinking for whole-building alerts?
Yes. Petros enables both hard-wired and software-based interlinking. Hard-wired interlink uses a common signaling line so all detectors sound when one alarms. Software interlink leverages the Petros controller: when any detector trips, the panel broadcasts a command to activate all sounders and strobe outputs in the configured group. This allows you to mix wired and wireless detectors and still achieve synchronized, building-wide notification.
What power supply specifications are required for Petros-integrated smoke detectors?
Petros panels provide 24 V DC nominal (19–28 V DC) at up to 500 mA per zone. Each photo-electric detector typically draws 50–80 µA in standby and 20–40 mA in alarm, so up to 12 units can share a single zone without exceeding capacity. For 120 V AC models, power must be taken from a dedicated, unswitched branch circuit protected by a 15 A breaker, with battery backup provided by the Petros UPS or local detector battery, meeting NFPA 72 requirements.
How does Petros facilitate monitoring and remote diagnostics of connected smoke detectors?
All detector zones are continuously supervised for open circuits, shorts, and ground faults. The Petros Connect web portal displays real-time status, sensitivity drift, last test date, and battery levels (for wireless units). Technicians can trigger a silent self-test or isolate individual detectors remotely, and email/SMS alerts are sent instantly upon alarm or fault, reducing on-site troubleshooting time.
What maintenance and testing procedures are recommended after integrating smoke detectors with Petros?
1. Monthly: Use the Petros dashboard to initiate an electronic self-test; confirm that each detector reports back a pass result. 2. Quarterly: Perform functional testing with canned smoke or a calibrated test kit, verifying that the Petros panel registers the alarm and resets correctly. 3. Annually: Inspect wiring, clean detector chambers with a vacuum or manufacturer-approved air puffer, and review event logs for excessive sensitivity drift. 4. Battery backup: Replace secondary batteries every 3–5 years or per manufacturer guidelines. All actions should be logged in the Petros maintenance module for compliance reporting.
