The TD-H Series handset intercoms are designed for applications where visual indication of an incoming call is required. The red LED mounted on the top front of the unit lights whenever a station receives a call. The TONE OFF switch at the bottom allows the user to turn the standard call tone on or off at any time. The LED will light regardless of the switch position. Ideal for applications where silent signaling is required, such as radio stations or sound booths.

Aiphone TD-1H/B – Frequently Asked Questions
1) How many call stations can an Aiphone TD-H master station handle?
The TD-H Series comes in five call capacities: 1-call, 3-call, 6-call, 12-call, and 24-call. Pick the capacity by how many stations that master needs to select and talk to. Wiring changes with capacity, so the count you choose also decides the cable you order.
2) What cable do I need to run for an Aiphone TD-H intercom system?
Cable depends on the call capacity. The TD-1H/B takes 6 conductor with overall shield (Aiphone #822206). The TD-3H/B and TD-6H/B take 10 conductor with overall shield (Aiphone #822210). The TD-12H/B and TD-24H/B take 16 conductor with overall shield (Aiphone #812216), and the TD-24H/B needs two runs of 812216 for full functionality. All of it is shielded cable, so plan the pathway accordingly.
3) How far apart can Aiphone TD-H master stations be wired?
Run length between master stations is 2,000 feet on 22 AWG and 4,800 feet on 18 AWG. If a building run is pushing past 2,000 feet, step up to 18 AWG rather than adding equipment.
4) What power supply does the Aiphone TD-H handset intercom need?
12V DC, from an Aiphone PS-1225UL. Each station draws 70mA, so total the stations on the system to size the supply. The power supply is a separate order; it does not come with the master station.
5) Can an Aiphone TD-H intercom release a door strike?
Yes, through the DE-UR. The door release output is a normally open dry contact rated 30V AC/DC at 1A. That contact switches a strike or maglock circuit; it does not power the lock, so the lock needs its own supply within that 30V/1A limit. A higher-draw lock needs a relay between the contact and the lock.
6) Which Aiphone intercom works in a sound booth or radio station where a call tone would interrupt?
That is what the TD-H Series is built for. A red LED on the top front lights whenever the station receives a call, and a TONE OFF switch at the bottom silences the standard call tone at any time. The LED lights either way, so someone on air still sees the call without hearing it.
7) Can the Aiphone TD-H master station sit on a desk instead of the wall?
Both. The handset cradle reverses for desk use, and the same unit surface mounts directly to a wall or to a 1-gang box. One part number covers all three mounting situations, so a receptionist unit and a corridor unit can be the same model.
8) Is the Aiphone TD-H handset intercom hands-free or do you have to pick it up?
Handset communication, full duplex, so both parties talk at once with no push-to-talk. Conversation is private through the handset rather than open on a speaker, which is the point of it in an office or exam room. It also supports multiple talk paths for communication and paging plus station-select break-in call, so a master can cut into a station already in use.
9) Does the Aiphone TD-H have a camera or video?
Audio only. The TD-H is a handset audio master station, so the visual element is the incoming-call LED, not a picture of the caller. If the job needs to see who is at the door, the TD-H is the wrong family and a video door station system is what to specify.
10) Is the Aiphone TD-H series rated for commercial buildings or is it residential gear?
Commercial. It is specified as a commercial-duty audio intercom master station, which is why the mounting, cable spec, and door release contact are all written for a building run rather than a house.
