1-Call Tek-Select Master Station. Can be desk/surface mounted with model IH400A cabinet. Optional All-Call and/or Music. Built-in electric door release pushbutton.

The Alpha Communications®/Tektone (SM401) Tek-Select II series intercom system is a fully featured, yet economical intermix type master/remote intercom for any application requiring a combination of up to two (2) master and/or remote stations, or as a single-call master tied into a larger capacity system. Each SM401 series master can call up to one (1) other master or remote station. The SM401 series master stations have a built-in amplifier and tone/buzz signal generator. They can be desk or surface mounted using an optional IH400A desk/surface cabinet. A built-in momentary door release button allows hook-up to your own 16VAC or 24VAC door opener (depending upon transformer used). The optional PK407A door opener relay allows connection to other voltages and types of door openers.

A wide variety of remote stations is available in ABS plastic, extruded aluminum, stainless steel, polished brass and painted finishes and with or without lighted buttons and privacy capability.

The SM401's can be intermixed with the SM404, SM406 and SM411 series masters, for other system capacity.

    WIRING REQUIREMENTS:
    From master to master (and to the PK400 control unit), run 6 common wires, and selective wire for every master -AND- remote on the system. For example, if you have four (4) masters and one (1) remote, you have five (5) TOTAL stations on the system. Add these five (5) wires to the six (6) common wires, and you need a minimum of 11 common wires between the master stations. Add 2 common wires from master to master, if All-Call is desired. If background music is desired, add 1 additional common wire from master to master, and run a 2-conductor #18AWG shielded cable from the background music source to the PK400 power supply unit (up to 100 feet maximum). If door release is desired, add 1 common wire to master to master cable, and run a 2-conductor #18AWG cable from each door opener to the PK400 control unit (up to 100 feet maximum).

    If ALL-CALL is not used, limit length of cable as follows:
    -------------------------------------------------------------------------------------------------------- Common Wire Gauge Size #22AWG - Maximum 500 feet (150 meters)
    Common Wire Gauge Size #20AWG - Maximum 800 feet (240 meters)
    Common Wire Gauge Size #18AWG - Maximum 1,200 feet (360 meters)

    If ALL-CALL is used, limit length of cable as follows:
    -------------------------------------------------------------------------------------------------------- Common Wire Gauge Size #22AWG - Maximum 250 feet (75 meters)
    Common Wire Gauge Size #20AWG - Maximum 400 feet (120 meters)
    Common Wire Gauge Size #18AWG - Maximum 600 feet (180 meters)

    Master stations may be loop wired. NOTE: due to common impedance coupling, tone signals may be amplified and heard by master stations monitoring other stations. With long wires, this interference may be quite loud. This effect may be reduced by using two (2) conductors for the terminal 'C' wire, or by using the next larger size conductor (#20AWG instead of #22AWG), or by wiring the system in a star pattern, where all stations home run to the PK400 control unit.

    For the OR642 or OR642W remote stations, run a 2-conductor twisted pair #22AWG cable from each remote station, back to the PK400 control unit, up to 250 feet. For runs up to 1,000 feet, use a 2-conductor (shielded) #18AWG cable. Only one (1) OR642 or OR642W remote may be used per system.

    For the IR143P remote stations, run a 4-conductor 2-twisted pair #22AWG cable from each remote station, back to the PK400 control unit, up to 250 feet. For runs up to 1,000 feet, use a 2-conductor (shielded) #18AWG cable.

    For the IR141U or OR541U remote stations, run a 2-conductor twisted pair #22AWG cable from each remote station, back to the RY402 in-use adaptor, up to 250 feet. For runs up to 1,000 feet, use a 2-conductor (shielded) #18AWG cable.

    For all other remote stations, run a 2-conductor twisted pair #22AWG cable from each remote station, back to the nearest master station only, up to 250 feet. For runs up to 1,000 feet, use a 2-conductor (shielded) #18AWG cable.

    Run a 2-conductor #18AWG cable from the 24VAC transformer to the PK400 power supply, up to 50 feet. NOTE: the audio and door opener and transformer cables must be in separate jackets and not in the same cable jacket.

    See system wiring diagram IL603 for more complete wiring information.
