20-040 and 20-046 COUNTDOWN TIMER
PRODUCT INFORMATION
Description
The Fike 20-040 & 20-046 Countdown Timers are accessory
units for use with Fike Fire Suppression Systems. They are
designed to provide a visual representation of time prior to
release of the agent. They require input from the Fike UL
listed control panel at the start of the pre-discharge state to
initiate their countdown sequence. This countdown can
either be a polarity reversal signal or relay activation,
depending upon the wiring option selected. The countdown
sequence does not reflect abort conditions at the panel. The
timers are sold with manual release switches and/or abort
switches. They are provided with back box of appropriate
size.

INSTALLATION & CHECKOUT
1) Disable the Control Panel Agent Release Circuit.
2) Remove all power from the control panel.
3) Connect the field wiring to the countdown timer
terminals according to the wiring diagram provided.(see
reverse side)
4) Adjust the Countdown Timer ten's and units settings for
the proper time that corresponds to the panel pre-
discharge countdown time.
5) Terminate field wiring on the abort and/or manual
release switch(s).
6) Apply power to the control panel. With the system
disarmed, test the system and verify the proper
operation of the timer. Make adjustment to timer units
settings to reflect accurate timing as per the control
panel. Test the operation of the abort and/or manual
release switch(s).

OPERATIONS
When the control panel enters the pre-discharge state it
initiates the signal to start the Countdown Timer. The timer
displays the countdown time as determined by the rotary
switch settings. After the time has elapsed, the L.E.D.
display will indicate '0' until power is removed (silenced or
reset) thus resetting the timer.
The operation and installation of the Abort and/or Manual
Release Switch(s) is described in Installation Guide 06-230.
