The loop powered door magnet is the latest innovation from Zeta Alarm Systems. The ZTA-DH is an addressable loop powered & loop controlled door holder. It takes all it’s power from the loop, so there is no need for a separate power supply or battery
The unit is designed to monitor the state of one or more single-pole, volt-free contacts and reports the contact status to Zeta compatible control panels.
ZIOU-DG – Zeta Addressable Input/Output Unit with Isolator provides two voltage-free, single pole, change-over relay outputs, a single monitored switch input and an unmonitored, non-polarised opto-coupled input.
The Zeta addressable input output units (ZIOU & ZIOU/230) are used to interface external equipment to any Zeta addressable fire alarm system.
The Zeta addressable input unit (ZIU) is used to interface external equipment which has a volt free normally open relay output to any Zeta addressable fire alarm system. The input is monitored with a 47K end of line resistor.
Zone monitors are used to connect conventional detectors to an addressable loop. This may be for economic reasons (due to conventional detectors being less expensive compared with addressable ones), or for technical reasons (the required detector may not be available in an addressable form (for instance flame detectors).
The Zeta addressable sounder circuit controllers (ZSCC & ZSCC/4) are used to connect any conventional alarm warning devices (for instance sounders, flashers or bells) to any Zeta addressable fire alarm system. It needs external power to be supplied from a suitable 24V power supply.
