Option “V” - Zone Voting Module
DESCRIPTION:
The ZV-91 Zone Voting Module is designed to supply an output signal upon the receipt of multiple zone alarm signals. The
standard configuration produces a single output signal after receipt of (2) input signals. The module is also available in a (3) input
version. The module can monitor up to sixteen inputs and provides (4) individual outputs for system function activation. This
module provides versatility in system logic programming including cross zoning (see cross zoning applications data sheet).
OPERATION:
Upon receipt of either two or three (preset at factory) negative going signals on the input terminals, the corresponding output
terminal is activated. The output is driven by a transistor switch to system negative. The illustration below depicts the most com-
mon configuration used in cross zoning applications. Four outputs are available, each output is controlled by (4) inputs. Normally
only the first two inputs are utilized, (1) for an alarm zone output and the other for a low air supervisory alarm output.
Option “W” - Auxiliary Power Supply
DESCRIPTION:
Option “W” increases the overall system power from 5.25 Amps to 9.0 Amps by utilizing an additional 24V regulated Power
Supply. Typically this additional power is required for panel devices such as Release Modules (Option “F”), Alarm Expander
Cards (Option “U”), etc. This regulated supply in conjunction with the MB-91A provides a completely supervised power source
for systems with power requirements that exceed that of the standard system power supply.
Only one auxiliary power supply can
be installed per system for Special Applications.
OPERATION:
The regulated power supply is rated and distributed uniquely for each application. Reference the Installation Wiring Diagram
(IWD) for each system to determine power distribution and availability. If the regulated power source is interrupted, the control
panel will go into a trouble condition, the “SYSTEM TROUBLE/SUP” indicator will flash and the on board piezo buzzer will acti-
vate. AC power loss of either the standard or auxilliary supply will result in a full system transfer to batteries.
