Programming Options (Continued)
TIME DELAYS AND RESTART PROGRAMMING
Two programmable time delays are available with the
CHECKFIRE 210 System. Time Delay #1 (TD1) starts
when a detection circuit receives an alarm condition (unless
programmed for Alarm Only or Cross-Zone Detection). Time
Delay #1 can be restarted by the operator. Time Delay #2
(TD2) starts at the end of TD1, and cannot be restarted.
The Time Delay #1 Restarts option allows the operator to
restart TD1 by pushing the “DELAY/Reset/Silence” button. This
gives the operator more time, if needed, before fire suppres-
sion system release and, if included, equipment shutdown. The
Time Delay Restart option is programmable to two restarts or
unlimited restarts.
Determine the proper time delay for the hazard, type of equip
-
ment, and operating environment. Time delay should be used
for safety of operator and others nearby. Time delay duration
should be as minimal as needed, because the fire suppression
system should be activated as soon as possible.
Time Delay and Restart programming provides the following
options:
• Time Delay #1 (TD1) is the initial time delay period and can
be programmed for 0, 5, 10 (default) or 15 seconds.
• Time Delay #2 (TD2) is a second time delay period between
equipment shutdown (if programmed) and system activa
-
tion, which can be programmed for 0, 5, 10 (default) or 15
seconds.
• Time Delay Restart of TD1 can be programmed for either 2
restarts (default) or unlimited restarts.
Planning should include a selection for each option.
CAUTION
TD1 is the delay period between an alarm condition and
equipment shutdown. If using the shutdown relay function,
programming TD1 to zero seconds results in immediate equip
-
ment shutdown and immediate start of TD2 upon initiation of
an alarm condition
CAUTION
TD2 is the delay period between TD1 and fire suppression
release. If using the shutdown relay function, programming TD2
to zero seconds results in immediate fire suppression release
at the same time as equipment shutdown.
CAUTION
!
Programming both Time Delay #1 and Time Delay #2 to zero
seconds results in immediate System activation following an
alarm condition. This situation could lead to immediate equip
-
ment shutdown (if using the shutdown relay function) or other
unforeseen issues which could result in significant property
damage or personal injury.
CAUTION
!
Delay of system operation may allow the fire to intensify, which
could result in a more difficult fire to suppress.
RELAY CIRCUITS #1 AND #2
The CHECKFIRE 210 System includes two programmable
internal, Form C relays (provides normally open (NO) and
normally closed (NC) contacts) that can be programmed to
transfer on a System alarm, fault or shutdown condition. These
relays can control external audible and/or visual signaling
devices for either alarm or fault indication. If programmed,
relay #2 can be directly connected to equipment shutdown
circuitry providing automatic equipment shutdown.
Contact Rating for both relays: 30 VDC nominal at 6 amps.
Relay #1 programming provides the following options:
• Alarm relay (default)
• Fault relay
Relay #2 programming provides the following options:
• Shutdown relay (default)
• Alarm relay
Display Module Location
1. Mount display module in full view, easily accessible, and
within reach of the operator. Select a flat surface that will
properly support the display module during all vehicle/
equipment operating and environmental conditions (e.g.,
shock and vibration). Note:
The display module should
never be mounted in an area subject to pressure washing
or steam cleaning.
2. Confirm the operator has access to the “PUSH To Activate
/ Alarm When Lit” and the “DELAY/Reset/Silence” buttons.
3. Select a location suitable for surface mounting (3/16 in.
(4.7 mm) maximum thickness), or bracket mounting. For
bracket mounting, use the optional CHECKFIRE 110/210
Mounting Bracket (Part No. 439564) and secure with
screws or bolts. The mounting surface must be flat to
avoid strain on the mounting bracket.
4. Confirm access for proper cable connection, periodic
inspection, and maintenance. If surface mounted, access
to the underside or rear of the mounting surface is neces-
sary. Review the surrounding area to confirm the location
will not interfere with normal vehicle/equipment mainte
-
nance or operation.
