Aiphone TW-TE-SP Tall Emergency Tower with Speaker and Strobe

The Aiphone TW-TE-SP is a 127-inch aluminum emergency tower designed to house IX | IXG Series IP emergency stations on campuses, parking lots, courtyards, and other outdoor assistance applications. Built from lightweight 6061-T6 aluminum, this tower weighs 87 lbs and delivers a 40W speaker output — loud enough to cut through ambient noise and draw attention in high-traffic public spaces. The combination of reflective EMERGENCY lettering on four sides, a 24V DC blue strobe light, and always-lit blue beacon makes the tower immediately recognizable during an emergency call. When a call comes in, the beacon flashes to signal an active emergency event.

Key Features

• 40W High-Power Speaker: Sufficient output to reach across large open areas (parking lots, courtyards, campus quads) without distortion. This matters because if your emergency notification system can't be heard, the call for help fails.
• 24V DC Strobe and LED Beacon: Operates on the same 24V supply as the IX Series stations. The constantly-lit beacon improves daytime visibility; flashing action during active emergency calls creates an unmistakable visual alert that draws attention faster than audio alone.
• Lightweight 6061-T6 Aluminum Construction: Corrosion-resistant alloy resists oxidation and pitting in salt-air, high-humidity, and coastal environments. At 87 lbs, the tower is manageable for two installers, but mass is sufficient to stay stable in moderate wind without overly aggressive anchoring.
• Reflective EMERGENCY Lettering on Four Sides: Ensures visibility from any approach angle — critical in parking structures and multi-directional campus layouts where a person in distress may not know which direction to face the beacon.
• 127-Inch Height (10.58 feet): Raises the speaker and strobe well above ground clutter, trees, and vehicles. This elevation creates line-of-sight to pedestrians across a typical parking lot or campus courtyard without requiring a separate pole.
• IX | IXG Series Station Compatibility: Works with IX-DVF-2RA, IX-DVF-2RA-FR, IX-DVF-RA, IX-DVF-RA-FR, IX-SSA-2RA, IX-SSA-2RA-FR, IX-SSA-RA, and IX-SSA-RA-FR emergency call stations. With the optional TW-SPL adaptor plate, it accommodates non-emergency IX-DVF and IX-SSA stations as well.

Integration and Compatibility

The TW-TE-SP houses emergency-ready IP intercom stations, making it part of a complete emergency communication network. It requires the optional TW-MKL L-bolt mounting kit to secure the tower in place — do not attempt freestanding installation without it. The tower's 24V DC strobe and LED beacon connect directly to the IX Series stations' auxiliary outputs, eliminating the need for a separate power supply or relay module. If you're retrofitting the tower to support non-emergency call stations, order the TW-SPL adaptor plate at the same time to avoid a second site visit.

Durability and Environmental Suitability

Weather and vandal resistance are built in: 6061-T6 aluminum resists rust; the tower design limits openings where water can pool or debris can accumulate. The reflective lettering is screened, not adhesive tape, so it does not peel after seasonal temperature swings. Typical deployments include open campuses (K-12 and higher education), multi-tenant commercial parking lots, healthcare facility courtyards, and event spaces.

Installation and Mounting

The TW-TE-SP must be mounted using the TW-MKL L-bolt kit (sold separately). Proper installation requires concreting the base anchors — plan for concrete curing time before energizing the beacon. The tower accepts a standard IX Series call station at its top or middle section, depending on aesthetic preference and visibility requirements. Refer to the TW-TA-SP & TW-TE-SP Installation Guide and TW-MKL Instructions for detailed anchor spacing and electrical connection details.

What's in the Box

The TW-TE-SP tower only — no mounting kit, call station, or internal wiring harnesses are included. You must purchase the TW-MKL L-bolt mounting kit separately, and you must specify the compatible IX Series emergency station you intend to house inside.

Frequently Asked Questions

Q: Does the TW-TE-SP come with a mounting kit?

A: No. The TW-MKL L-bolt mounting kit is required and sold separately. Order it at the same time to ensure proper installation.

Q: Can I use a non-emergency IX Series station in the TW-TE-SP?

A: Yes, but you need the optional TW-SPL adaptor plate. Without the adaptor, only emergency stations (IX-DVF-2RA, IX-SSA-2RA, etc.) will fit.

Q: What voltage do the strobe and beacon require?

A: Both operate on 24V DC, sourced from the IX Series station's auxiliary outputs. No separate 24V supply is needed if your station is already powered.

Q: Is the tower suitable for coastal or salt-air environments?

A: Yes. The 6061-T6 aluminum alloy is corrosion-resistant and suitable for high-humidity and salt-spray conditions. The tower should still be rinsed occasionally to remove salt buildup on the lettering and beacon lens.

Q: What size emergency station fits inside the TW-TE-SP?

A: The tower accommodates IX Series emergency call stations. Check the compatibility list (IX-DVF-2RA, IX-DVF-RA, IX-SSA-2RA, IX-SSA-RA and their FR variants) before purchasing.

Q: How is the beacon wired to the station?

A: The strobe and LED beacon connect to the emergency station's auxiliary outputs via a simple terminal connection. Refer to the Screwless Terminal Strip Installation Guide for wiring details.

The TW-TE-SP is purpose-built for campus and public-safety deployments where audio alert range and visual beacon presence are non-negotiable. The 40W speaker and 24V strobe combination on a 127-inch tower makes this a standout piece of emergency infrastructure — it's not hiding in a corner, and it's loud enough that someone in distress doesn't have to be standing directly at the call station to hear the response.

Technical Highlights:

• 40W Speaker Output: Sufficient to exceed ambient noise in parking lots and courtyards without clipping. This is a real deployment difference from smaller horns; a 40W system can be heard across a multi-acre campus or parking structure, whereas a 10–15W unit leaves dead zones where audio fails to project.
• 127-Inch Height + Reflective Lettering (4 sides): Elevation and multi-directional visibility combine to ensure the tower is found and recognized from any approach angle. In a parking lot or courtyard, a person in distress doesn't need line-of-sight to the ground or a specific direction — the beacon and lettering work in peripheral vision.
• 6061-T6 Aluminum + 24V DC Strobe & LED: Corrosion resistance matters in humid and coastal regions; the dual-beacon system (always-lit LED + flashing strobe during active calls) ensures redundancy if one light fails. The strobe is the attention-getter; the always-on LED is the confidence signal that the system is operational.

Deployment Considerations:

• The TW-MKL L-bolt mounting kit is mandatory — this is not a free-standing tower. Plan concrete anchoring lead time and ensure the base location can support a 24-hour concrete cure before power-up.
• The tower houses only IX Series stations; if you're mixing Aiphone product lines or integrating third-party intercoms, verify station compatibility before ordering. The TW-SPL adaptor plate extends flexibility to non-emergency stations but adds cost and complexity.
• The 40W speaker projects omnidirectionally; if the deployment is in a noise-saturated area (highway adjacent, industrial zone), expect the audio to blend with background noise at distances beyond 100–150 feet. For very long-range coverage (>300 feet), a second tower or supplementary audio system may be necessary.

The TW-TE-SP is the right choice for K-12 campuses, healthcare facilities with outdoor courtyards, and commercial parking structures where emergency notification must be both audible and visually unmistakable. It's not a subtle system — it's meant to be found and activated under stress.
