Maxim III installation v installation planning 1. Amplifer/Receiver: Choose location the based on accessibility requirements and wiring constraints for power, speakers, and audio devices. Ceiling Sensor: Centrally locate on ceiling; maintain line of sight; keep away from direct light and electrical interference. Speakers: Mark location for wall mount vs. ceiling mount, and confirm wiring run to the amplifier. Ensure speakers evenly cover the listening area.
product description installation of ICS-55 ceiling sensor The ideal location for the ceiling sensor is in the center of the room's ceiling. The ideal installation is flush mounted on a white, reflective ceiling like the acoustic drop-down style. This will ensure 360º coverage and will minimize the transmission distance for more reliable performance. power “on” LED Green light indicates that the sensor is receiving power from the receiver.
Maxim III installation installation of speakers The IMA-520 (and IMA-524) has two channels of amplified audio, rated for a minimum 4-ohm speaker load. There are two blue Phoenix style speaker connectors on the back panel, each providing two pairs of speaker terminals. The top connector provides connection to both channels as does the bottom connector. Each is wired in parallel to the other as shown below. These are the acceptable wiring methods.

Lay ceiling tile face down on clean flat surface 5. Lay tile bridge on ceiling tile and center it 6. Trace and cut the large hole 7. Strip the speaker cable ends, approx. ½" 8. Route speaker wire from speaker opening to amplifier 9. Reinstall ceiling tile with tile bridge in place above the hole 10.

For older units see notes at the end of this section. New units: A paging system may be connected to the Maxim III. The panel labeling is based on a 25-volt paging input signal. The Page Input impedance switch has three labeled positions (based on power draw at 25V): • 0.1W DRAW • 1.

Maxim III integration transmitter RS-232 feature The RS-232 feature allows the user to remotely operate the line level media inputs via a convenient wall panel controller. Audio levels very often need to be adjusted when switching from computer audio to DVD players and other audio sources. Such operations as level UP, DOWN and MUTE are easily accomplished via a typical eight button controller, as shown here.
RE-232 and Security Alert contacts security alert feature Effective for shipments after this date of new or reprogrammed units. Serial numbers beginning with A19 and later (letter or number is A, B, C… and number is 19, 20, …). The Maxim III security alert feature, when triggered by an IRT-60 sapphire mic on Channel A, creates a relay contact closure or opening. The back panel connection is a normally closed and normally open terminal paired with the common terminal.
Maxim III integration security alert features To check the mode Note the LED color on the power button at the TL logo. If power state is ON (Blue LED at power button), press once to set power state OFF (Red LED). • If Red, then you may start the process. • 1. 2. 3. Press and hold the power button (in Red state) for the entire process. After 4 seconds, the LED will change colors. Note the number of RED flashes AFTER the GREEN flash.
