Adams Rite 29-0218 – Frequently Asked Questions

1) What voltage does the Adams Rite 29-0218 piezo horn run on?
The 29-0218 piezo horn works on 12VDC, 16VDC, or 24VDC, so it drops onto whichever DC supply is already feeding your electric strike without a separate transformer. It is a DC-only device, so if the strike circuit is running on AC you need a DC source for the horn.
2) What does the Adams Rite 29-0218 horn actually do on an access control door?
It's an audible strike activation indicator. When the DC electric strike is energized, the piezo horn sounds, so someone at the door knows the strike has released and can pull it open. It isn't an alarm or a delayed egress sounder, it just gives audible feedback that the release fired. Common on lobby and vestibule doors where the buzz is the cue to push.
3) Will the Adams Rite 29-0218 horn work with my Adams Rite electric strike?
Yes. The 29-0218 is built to pair with Adams Rite electric strikes and electrified hardware, and it takes its power from the same 12, 16, or 24VDC circuit that drives the strike. Wire it across the strike so it sounds while the strike is energized.
4) What is the difference between the Adams Rite 29-0218 piezo horn and the RCI 914 delayed egress sounder?
They solve different problems even though both are audible devices. The Adams Rite 29-0218 is a piezo electric horn that sounds when a DC electric strike is energized, giving audible confirmation that the strike has released, and it runs on 12VDC, 16VDC, or 24VDC. The RCI 914 Series is a delayed egress sounder with field-selectable volume output up to 102dB, which annunciates the delayed egress cycle at the door rather than indicating strike activation. If the requirement is a local audible cue tied to strike power, the 29-0218 is the piece; if the requirement is the alarm that accompanies a delayed egress sequence, the 914 is the one to specify.
5) Do I need an audible strike buzzer or a delayed egress sounder?
Two different jobs. The Adams Rite 29-0218 piezo horn sounds when a DC strike is energized, telling a visitor the door is released. If what you need is a sounder that annunciates when someone pushes on a controlled exit during the egress delay, that's a different device, such as the RCI 914 Series delayed egress sounder with field-selectable volume up to 102dB. Pick the horn for entry feedback, the 914 for egress alarming.
6) What else do I need to order with the Adams Rite 29-0218 horn to finish the job?
You supply the DC power source and the wiring. Confirm the supply voltage and current capacity, then run wire of an appropriate gauge to the horn per the wiring diagram, with the power off while you land it. If the run needs a surface enclosure at the button or the horn location, a single gang surface mount box like the Cal-Royal 8641-SM covers that. Nothing else about the strike itself changes.
7) Can the Adams Rite 29-0218 be used as a request-to-exit or latch monitor signal?
No. The 29-0218 is an output device, it makes noise when it's powered. It does not send a signal back to a panel. For a switch that reports exit or latch status, you want a REX or monitor kit matched to your hardware, such as the Command Access REX-KIT-ML for ML1-Series mortise locks, the SCHLBMKIT-ML latchbolt monitor for Schlage L9000 mortise locks, or the CYREXKIT-ED field REX kit for Corbin 5000 and Yale 7000 exit devices.
8) Can the Locknetics RDB4 relay board be used in place of an Adams Rite 29-0218 horn?
No, those are not interchangeable. The Locknetics RDB4 is a 4 output relay distribution board, sold as a board only, used to distribute and switch control signals inside an access control cabinet. The Adams Rite 29-0218 is a piezo electric horn that produces the audible tone itself when a DC strike is energized on 12VDC, 16VDC, or 24VDC. An RDB4 can switch the circuit that drives an annunciator, but it makes no sound; if the job calls for audible feedback at the opening, the horn is still required.
9) If a strike opening needs weather protection rather than an audible indicator, what should be specified instead of the Adams Rite 29-0218?
Specify the HES 1000-102, a 1006 Series Grade 1 rain guard intended for rain or high dust areas. It shields the strike itself in exposed or dirty conditions. The Adams Rite 29-0218 addresses a different need entirely: it is a piezo horn that sounds when the DC strike is energized, on 12VDC, 16VDC, or 24VDC. An exterior strike opening that needs both monitoring and protection uses the two together rather than one in place of the other.
10) For door status feedback, is a request to exit switch kit an alternative to the Adams Rite 29-0218 horn?
They report different things and neither replaces the other. Kits such as the Command Access REX-KIT-ML for ML1-Series mortise locks and the Command Access SCHLBMKIT-ML latchbolt monitor switch kit for Schlage L9000 mortise locks, which uses an SPDT configuration, are field installable switches that send a contact closure back to the panel when the lever is turned or the latchbolt moves. The Adams Rite 29-0218 produces an audible tone locally when the DC strike is energized, on 12VDC, 16VDC, or 24VDC. Head end reporting calls for the switch kit; on site audible confirmation for the person at the door calls for the horn.
11) Is the Adams Rite 29-0218 horn rated for commercial buildings or is it a residential part?
Commercial. It's specified into building security systems, retail, healthcare, schools, industrial facilities and multi-tenant residential properties, all places where a controlled door needs an audible release cue. It's an electronic accessory, not a mechanical one, so it needs a powered strike circuit to be of any use.
12) I'm standardizing access control accessories across a building, is the 29-0218 the same part for every door?
It's a single model, 29-0218, with no size, hand or finish choice to specify, so every opening gets the identical part number. That makes it straightforward to stock as an MRO line item. The only thing that varies door to door is the DC supply it lands on, and it covers 12, 16 and 24VDC.
13) What should be used for an audible restroom occupancy or two-door interlock instead of the Adams Rite 29-0218?
The DynaLock 8500-2 is a two-door communicating bathroom system, built to coordinate a pair of doors serving one restroom. That is a complete control arrangement for the opening pair, not an annunciator accessory. The Adams Rite 29-0218 is a single piezo horn wired to a DC electric strike circuit at 12VDC, 16VDC, or 24VDC, and it has no door-to-door logic of its own. A restroom pair that must lock against each other is an 8500-2 application; a single strike that needs an audible release tone is a 29-0218 application.
