QMT-5300A, QMT-5302 and QZT-5302 Installation and Operation Instructions

QMT-5300A, QMT-5302 and QZT-5302 Instructions

Introduction

MIRCOM’s Fire Fighters’ Telephone may be used either alone as a Single Zone System (using the QMT-5300A or
QMT-5302 Master Telephone by itself), or as a Multi-Zoned System (with the QZT-5302 Zone Adders).

Mounting

The modules mount in any of the BB-1000 Series Remote Annunciator enclosures except for the QMT-5302 Master
Telephone which mounts into a BB-5008 or BB-5014 backbox. For the QMT-5300A Master Telephone, the included
extended window module must be installed in place of the existing window. In any BB-1000 enclosure, the QMT­5300A is mounted bottom-most, and one to five QZT-5302s above, for a total of 60 Telephone Zones. In any BB­5008 enclosure, the QMT-5302 should be mounted below the QZT-5302s and beside the master telephone for ease
of ribbon cable installation.

Labels

Two slide-in labels are supplied with the QMT-5300A ; the NP-735 is used for Single Zone and the NP-736 for Multi­Zone. Slide-in label NP-896 is provided with the QMT-5302, use the Connect for Single Zone or Clear All label for
Multi-Zone. The QZT-5302 includes blank labels for Telephone Zone information.

Chassis Ground

Connect one of the BB-1000 Series Backbox, BB-5008 or BB-5014 Earth-Ground points (Chassis Ground) to Earth
Ground (cold water pipe).

Power Supply

Only the telephone master QMT-5300A or QMT-5302 module requires power. It can be powered with a 24 VDC,
200 mA external DC power source (filtered or un-filtered, such as 4-wire smoke or auxiliary power from a Fire Alarm
Control Panel), see Fig.1

Jumpers

There are three jumpers on the QMT-5300A and QMT-5302 PCB showing at the top of the black chassis. For a
Single-Zoned System JW1 and JW2 have jumpers installed, JW3 does not. For a Multi-Zoned system with QZT­5302s, JW1 & JW2 jumpers are removed, and JW3 is installed. There is one jumper, JW1, on each QZT-5302 Zone
Adder, and a jumper is installed only on the last QZT-5302.

Connectors

On the QMT-5300A and QMT-5302, P1 is used only for Multi-Zoned Systems. P2 is the connection for the Master
Telephone Handset. On the QZT-5302, P1 connects to the QMT-5300A, QMT-5302 or previous QZT-5302, and P2
connects to the next QZT-5302.

QMT-5300A/QMT-5302 Master Telephone Wiring

Figure 1 shows the wiring for QMT-5300A and QMT-5302. A Fire Alarm Control Panel’s Detection Zone (should be
configured as Trouble-Only or Non-Latching Supervisory) is used to annunciate Telephone Trouble. This is
connected to the QMT-5300A or QMT-5302 TROUBLE terminals (polarity does not matter), and the ELR device for
that zone is connected to the QMT-5300A or QMT-5302 ELR terminals. DC Power (24 V DC, filtered or unfiltered at
200 mA) is connected to the 24 V DC terminals.

If the Master Telephone is being used alone as a Single-Zone System, the NP-735 Label is used or Connect label
from NP-896, and Jumpers are placed on JW1 and JW2 only. The one Telephone Zone connects to the TEL-CKT
terminals. The 10 Kohm ELR resistor that is shipped with this unit is connected after the last Remote Telephone on
the Zone and the negative black jumper is removed for Class B. For Class A wiring, remove both red and black
jumper wires and wire from OUT + - to the remote telephones and back to RET + -.

If the Master Telephone is being used as a Multi-Zoned System with QZT-5302s, the NP-736 Label is used or Clear
All label from NP-896, and a Jumper is placed on JW3 only. The TEL-CKT terminals are left as is. Telephone Zone
wiring is done via the QZT-5302s.
