Viking Electronics SA-1H Infrared Remote Controllable Paging Horn
The Viking Electronics SA-1H is a 5-inch paging horn engineered for access control, emergency notification, and multi-tenant intercom systems running the Viking SA Series 2-wire protocol. This unit combines onboard amplification, infrared remote control detection, and a frequency response optimized for speech clarity—making it the right choice when you need audible output from a building-wide announcement or entry-point alert system without additional amplifier hardware.
Key Features
- 1.5-watt power amplifier: Delivers audible paging output directly from the SA Series 2-wire network—no separate amp rack or external speaker driver needed. Adequate for small-to-medium commercial spaces, tenant lobbies, and secured corridors where localized announcement is the goal.
- 5-inch horn form factor: Physical size provides directional acoustic coverage and mounting versatility on walls or ceilings. Larger than smaller piezo units, so it cuts through ambient noise in moderately noisy environments (loading docks, retail floors) better than miniature options.
- Infrared remote control receiver: Integrates IR remote triggering for selective paging zones—lets you trigger announcements from a handheld remote without wiring a separate control button. Useful in multi-zone deployments where zone selection from a central desk or mobile device simplifies workflow.
- 400Hz to 7kHz frequency response: Optimized for intelligible speech reproduction. This range emphasizes the consonants and vowels that make announcements clear in busy environments, avoiding the tinny sound of cheap speaker systems.
- SA Series 2-wire protocol (40VDC + audio): Connects to Viking's access control and intercom ecosystems via a single twisted-pair plus power line. Eliminates the need for separate analog audio and control wiring—one cable per horn reduces installation labor and conduit congestion.
- Operating range: 32°F to 90°F, 5% to 95% non-condensing humidity: Suitable for climate-controlled indoor installations (offices, lobbies, secure rooms) and lightly sheltered semi-outdoor spaces (covered entry vestibules, indoor parking garage stairwells). Not rated for direct rain or extreme cold—avoid unprotected outdoor mounting or harsh industrial environments.
Integration & Compatibility
The SA-1H is a proprietary endpoint in the Viking SA Series 2-wire ecosystem. It integrates with Viking entry phones (E-10A, E-20B models and compatible systems), access control panels, and intercom hosts that support the 40VDC + audio protocol. If you are already running Viking SA Series infrastructure—door phones, indoor/outdoor entry stations, or a Viking commercial intercom system—the SA-1H adds distributed paging and emergency alert capability with zero additional wiring complexity beyond the 2-wire pair.
IR remote control enables flexible zone triggering from handheld devices, reducing reliance on hardwired button stations. This is particularly valuable in multi-tenant or multi-floor deployments where a single control point (desk, security office, or mobile device) needs to trigger announcements across multiple zones or override specific horn locations.
Deployment Context
The SA-1H is most effective in small-to-medium commercial settings: office parks, medical clinics, retail tenancy buildings, and secure facilities where access control and life-safety paging are tightly integrated. Its 1.5-watt output is sufficient for typical background announcement and emergency alert in spaces up to approximately 1,000–1,500 square feet with modest ambient noise. In large open warehouses or outdoor yards, multiple units or higher-power external amps become necessary.
Indoor mounting on walls or ceilings is straightforward; the 3.0" × 4.4" × 1.4" receiver dimensions fit standard electrical boxes or surface-mount enclosures. Ensure the installation location has adequate 40VDC supply from the SA Series control panel—most panels provide limited 2-wire pairs, so verify you have an available port before committing to the installation plan.
Frequently Asked Questions
Q: Can the SA-1H be used with non-Viking access control systems?
A: No. The SA-1H operates exclusively on the Viking SA Series 2-wire protocol (40VDC + audio). It is not ONVIF-compatible and does not work with analog audio lines or third-party IP-based systems. It is a proprietary Viking device.
Q: What is the maximum coverage area for the SA-1H's audio output?
A: With 1.5 watts of amplification, the SA-1H is designed for small-to-medium indoor spaces (approximately 1,000–1,500 sq ft). Actual coverage depends on ambient noise, room acoustics, and listener distance. In large open spaces or high-noise environments, multiple units or an external amplifier are recommended.
Q: Is the SA-1H suitable for outdoor mounting?
A: The SA-1H is rated for 32°F to 90°F operating temperature and 5–95% non-condensing humidity. It is designed for climate-controlled or lightly sheltered indoor installations. Direct rain, extreme cold, or wet environments will degrade performance or cause failure. For outdoor applications, consult Viking for weatherproof alternatives.
Q: Does the SA-1H require an external power supply?
A: No. The SA-1H draws power from the Viking SA Series 2-wire network (40VDC). It connects directly to the control panel via the 2-wire pair—no additional PSU or power cable is needed beyond the panel's output.
Q: Can multiple SA-1H units be controlled independently via IR remote?
A: Yes. Each SA-1H has an onboard IR receiver and can be assigned a unique IR address or zone code. This allows selective paging to specific horns from a single remote. Consult the Viking SA Series programming guide for zone assignment and remote pairing procedures.
Q: What warranty does the SA-1H carry?
A: Specific warranty terms are not listed in the available product documentation. Contact the manufacturer or a Viking channel partner for warranty details at the time of purchase.
The Viking Electronics SA-1H is a straightforward choice if you're deploying emergency notification or zone-based paging within an existing Viking SA Series infrastructure. The 1.5-watt onboard amplifier and 5-inch horn are sized appropriately for small commercial interiors—office wings, secured entry lobbies, and tenant common areas. The SA-1H eliminates the need to run separate amplifier hardware, which saves both conduit runs and equipment costs in retrofit installations.
Technical Highlights:
- 400Hz–7kHz frequency response: Speech-optimized range means your announcements stay intelligible even in moderately noisy backgrounds. You're not fighting tinny, high-frequency artifacts like cheaper piezo units deliver.
- 1.5-watt amplifier integrated: Eliminates external amp requirements for small-to-medium coverage zones (roughly 1,000–1,500 sq ft indoor). Reduces both installation cost and equipment footprint—the horn and amp are one device.
- SA Series 2-wire (40VDC + audio): Single twisted-pair connection to your Viking panel means less wiring labor and one fewer conduit run per zone. In multi-story tenant buildings or retrofit scenarios, that's a real time and cost saving.
- IR remote receiver built-in: Assign each horn a unique IR zone code and trigger announcements from a handheld remote. Valuable in deployments where a security desk or mobile command point needs to page selected zones without hardwired button stations.
Deployment Considerations:
- Operating temperature limit of 32°F–90°F rules out unprotected outdoor or industrial freezer installations. Verify your install location stays within those bounds—lightly sheltered vestibules and climate-controlled stairwells are fine, but exposed loading docks are not.
- The 1.5-watt output is modest. In large open warehouses, gymnasiums, or high-ambient-noise environments (sheet-metal shops, highway rest stops), you'll need multiple SA-1H units or an external amplifier to achieve adequate SPL. Run a quick site survey before committing.
- IR remote control requires line-of-sight to the horn receiver. If you're installing the horn behind a solid wall or in a ceiling void, the IR signal won't reach it—plan remote placement accordingly, or rely on hardwired button stations instead.
Best fit: small-to-medium commercial interiors already running Viking SA Series access control or intercom infrastructure—office parks, medical clinics, secure entry lobbies, and retail tenancy buildings where emergency notification and zone-based paging are integrated into the access control workflow.
