Description
The Zeta Quad Zone Monitor Unit (ZTZM/4) is used to
connect any conventional Detectors (such as Smoke, Heat,
or flame) to any Zeta Analogue Addressable fire alarm system.
It has 4 detection circuits, and needs external power to be
supplied from a suitable 24 V PSU.
The unit has a built in loop short circuit isolator to help
keep the unit operational in the event of a problem on the
addressable loop wiring.
It has Internal indication LEDs for Zone Alarm (red), and Zone fault (yellow) for
each of the detector circuits. It also has one for addressable loop fault (Isolator
active).
Connections & Address Setting
The ZTZM/4 has the following connections:-
Loop IN +
Loop IN –
Loop OUT +
Loop OUT –
ZONE INPUT (4 sets of 2 connections)
SND SUPPLY (2 connections, +24V & 0V)
Normally the loop cables will be connected one pair of +/- to the IN terminals, and the other pair of
cables to the OUT terminals. To temporarily bypass the isolator (eg for a DVM cable continuity
check), fit a shorting link to position J1.
The ZTZM/4 is addressed by 3 rotary switches, one for 100`s one for 10`s, one for units. Select an
address between 1 & 123. This unit will answer at 4 different addresses. The address set on the unit
is for circuit 1, address +1 for circuit 2, address +2 for circuit 3 and address +3 for circuit 4.
