DESCRIPTION

The Quad Zone Unit (QZU-L) provides the 7200 Series Fire Alarm Control Panel with four (4) Class A, Style D or Class B,

Style B conventional, hard-wired, zone initiating circuits. Each circuit is field programmable for waterflow detection/supervi-

sory monitoring on a common multi-level detection circuit. Each circuit also provides verification capability for two-wire

smoke detectors.

The Eight Zone Unit (EZU-L) is similar to the Quad Zone Unit (QZU-L), except it provides eight (8) Class B, Style B con-

ventional zone initiating circuits. Class A, Style D wiring return connections are made to the optional Eight Zone Daughter

Board (EZD-L) which contains end of line devices and is mounted between the backboard and its associated EZU-L.

The QZU-L initiating circuits each contain a red “ALARM” LED and a yellow “TROUBLE” LED, along with a supervised,

power limited LED annunciator output for each zone. The EZU-L likewise contains “ALARM” and “TROUBLE” LEDs,

while supervised power limited annunciator output from the EZU-L circuits is available via an associated Eight Zone Daugh-

ter board (EZD-L), or Eight Zone Annunciator board (EZA-L). The EZA-L does not contain Class A circuitry.

Each initiating circuit also incorporates a zone “DISCONNECT” user switch, for individual initiating circuit control and

programming functions.

The QZU-L and EZU-L will accommodate FCI Approved, UL Listed, compatible two-wire smoke detectors. See the FCI

Addendum, P/N 9000-0427 for a list of detectors and quantities that can be accommodated per circuit.

Pluggable terminal blocks are provided with each unit for the connection of field wiring. These blocks will accommodate

wire sizes up to 12 AWG.

The QZU-L and EZU-L each occupy a full-unit size space in the cabinet, and mount in any available module position below

the SCU System Control Unit.
