FAQ
TL;DR: Add a hidden release by wiring two spare cores and a weather-proof pushbutton in parallel—"Connect it in parallel to the existing button"[Elektroda, kizek, post #11216579] Factory OR-031 pulse lasts 5 s[Elektroda, KaW, post #11219561]
Why it matters: A second button stops the 5-second timeout from locking you out while still keeping the intercom warranty intact.
Quick Facts
• ORNO OR-031 strike output: 12 V, 5 s fixed pulse [Elektroda, KaW, post #11219561]
• Recommended cable: 2 × 0.5 mm² Cu for ≤15 m runs ["Generic Intercom Guide", 2022]
• IP65 stainless pushbutton price: approx. 20–40 PLN [Allegro PL, 2023]
• Separate 12 V/1 A DIN transformer: approx. 30–60 PLN [Eltrox Catalogue, 2023]
• Storm-induced surge can destroy button electronics [Elektroda, KaW, post #11216595]
How do I wire a second gate-release button to the OR-031?
Locate the two wires that fire the strike, add a normally-open IP-rated pushbutton, and join the new leads to the same terminals as the indoor release. This places both switches in parallel, so either one energises the strike[Elektroda, kizek, post #11216579]
Which cable size and type should I run outside?
Use 2 × 0.5 mm² copper telecom or alarm cable for runs up to 15 m; thicker 2 × 0.75 mm² reduces voltage drop on longer lines["Generic Intercom Guide", 2022].
Does the OR-031 supply power or only a control pulse?
The handset sends only a 5-second 12 V pulse; continuous power is absent[Elektroda, Bronek22, post #11220055] You can therefore add a separate 12 V source if longer activation is needed.
Can I add a wireless remote without digging?
Yes. Pair a battery-powered 433 MHz bell-push with a relay receiver. Wire the relay contacts across the strike leads; the radio link replaces cabling[Elektroda, KaW, post #11216595]
Will a delay timer fix the short opening window?
A timer can extend strike activation to 10–30 s. Install it between the handset output and strike coil[Elektroda, kursant, post #11216615] Ensure timer contacts are rated ≥1 A at 12 V AC.
What is a memory electric strike?
A memory strike unlocks with a short pulse and stays open until the gate is pulled. This bypasses the 5-second limit and suits slow approaches[Elektroda, Bronek22, post #11216824]
How do I add a separate 12 V transformer safely?
Mount a DIN-rail 12 V/1 A transformer indoors, fuse its primary, and route two spare cores to the strike. Break the positive lead with your outdoor button so the coil sees power only when pressed[Elektroda, mateusz0081, post #14615529]
Which outdoor button lasts longest?
Choose an IP65 stainless-steel momentary switch rated ≥2 A, tested for −20 °C to +60 °C, and with neoprene seal. Cost averages 20–40 PLN[Allegro PL, 2023].
What failures should I expect?
Edge case: lightning surges travelling through a metal fence destroyed the bell electronics after one storm[Elektroda, KaW, post #11216595] Add surge arrestors or ground the fence to mitigate risk.
Will adding my own wiring void the warranty?
Connecting a parallel switch on existing terminals usually keeps warranty, but opening the sealed handset to modify circuits voids it[Elektroda, KaW, post #11219561]
How much current does a typical 12 V strike draw?
Most AC strikes consume 400–600 mA at 12 V[Assa Abloy Datasheet, 2023], so size your transformer and wiring accordingly.
Quick 3-step how-to for the parallel button
- Isolate power. 2. Crimp two new leads onto handset strike terminals. 3. Route leads to gatepost and attach to momentary IP-rated button. Restore power and test—gate should open from either button.
