L-TRONIK PMA-COMZ6 - 6-zone call station for COM v2 stages with RS485 and 2/4-tone buzzer

The L-TRONIK PMA-COMZ6 is a professional 6-zone call station designed for industrial sound systems and distributed PA systems . It allows you to select any zone, several zones, or all zones for completely flexible announcements, incorporating a pre-alert bell with 2 or 4 tones to improve intelligibility in noisy environments. Its RS485 communication over RJ45 port enables long-distance installations and the possibility of chaining (cascading) up to 6 desks , ideal for hotels, shopping centers, schools, sports complexes, or large retail stores.

The system implements address-based priorities : after powering on the equipment, each desk can be assigned a priority by holding down the zone number. Address "01" has the highest priority and can override the others (duplicate priorities are not permitted). It includes a power-saving function : if no signal is detected within 1 minute, the microphone automatically goes into standby. For distances greater than 50 m , a 24 V DC power supply is recommended, and the maximum RS485 communication distance is 1 km under standard conditions. Microphone level and call tone adjustment are available from the desk itself.

With a compact desktop format ( 175 × 147 × 54 mm , without microphone boom) and a weight of 1.0 kg , the PMA-COMZ6 integrates easily into counters, reception areas or control rooms, providing a robust and reliable solution for zone-based PA on 70/100 V lines managed by COM v2 power units.

Frequently Asked Questions

• How many stations can I connect? Up to 6 units on the same RS485 line.
• What is the maximum distance? Up to 1 km via RS485 (use of appropriate cabling is recommended).
• How do you manage priority? After turning it on, press and hold the zone button to assign a direction/priority; 01 is the highest and cannot be repeated on another desk.
• Do I need an external power supply? 24 V DC is recommended for distances greater than 50 m .
