Description
The dual contact zone module, Model ZN-31U, is de-signed to provide two (2)
detector line circuits incorporat-ing contact type devices. These devices may
be manual stations, waterflow switches, thermal detectors, relay contacts,
etc. Each circuit provides Class “B” supervision. The module also contains two
(2) red LED “Alarm” lamps and two (2) yellow LED “Trouble” lamps, one of each
for each circuit.
Upon operation of any shorting type device installed on the detection circuit,
the system will lock into alarm condition initiating the start of the
sequential functions designed into the system, such as ringing alarm bells,
operating coded alarm transmitters, closing doors, shut-ting down fans and
equipment, recalling elevators, etc. In addition to the system alarm, the red
LED alarm lamp on the face of the module for the particular zone in alarm will
be illuminated. The module also provides a current-limited output signal for
the zone in alarm for activating a supple-mentary alarm relay module , or
annunciator module. The zone alarm indicating circuits and signaling lamps are
reset from the system control panel.
The yellow LED trouble lamps (one for each circuit) will illuminate should a
break occur in the detector lines. Such a condition will initiate a system
trouble signal. The yellow LED trouble indicators will be extinguished upon
restora-tion of circuit integrity or upon receipt of any system alarm.
Both red and yellow LEDs can be lamp tested from the system control panel.
The model ZN-31U is placement supervised, providing a system trouble signal
upon removal from the system.
The unit is Underwriters Laboratories, Inc. listed.
Optional Features
The Model ZN-31U can be supplied in normal “lock-in” or “non lock-in” modes as desired.
Engineer and Architect Specifications
Dual detection line circuit monitoring shall be provided by a Cerberus
Pyrotronics dual contact zone module, model ZN-31U. This module shall be
system interconnected by a ten-pin plug and harness assembly and shall be
operable with the main control panel.
Each detector line shall consist of a two wire circuit terminating in an end
of line device and shall accommo-date contact type devices. Each circuit shall
provide Class “B” supervision.
Upon operation of any contact device installed in the circuit, the system
shall lock into alarm and the red LED alarm indication lamp (one for each
circuit) mounted on the face of the module shall illuminate. A yellow LED
trouble indicating lamp (one for each circuit) also on the face of the module
shall illuminate should a break occur in the detection circuit.
All LEDs shall be lamp tested from the system control panel.
The model ZN-31U shall be placement supervised and shall be Underwriters
Laboratories, Inc. listed.
