Manual Restart
Upon activation of an ALARM event, the CRM4 relays will activate and remain active even after the control
panel is reset. After reset, the fan restart sequence must be initiated manually using any of the following
sources: 1) press the control panel’s “ENTER” key, 2) peripheral device (i.e., remote display or input/output
card) switch configured for Fan Restart, 3) control panel’s “AHU ON” function that can be found in
MAINTENANCE MENU 2. Once initiated, the panel will start the automatic fan restart sequence and the AHU
Shutdown relays will deactivate according to their programmed time delay allowing the startup of the AHU fan
motors to be staggered. Once all relays are deactivated, the panel will return to the ‘System Normal’ screen.

Exhibit 3-15: Manual Fan Restart Display
•
Row A – Displays “FOR FAN RESTART->ENTER”, indicating that the panel is waiting for the
operator to press a fan restart switch. Once a restart switch is pressed, the Automatic
Restart screen (Exhibit 3-14) will be displayed and the restart delay timers will activate.
Note:
CRM4 relay(s) will remain in the activated state through a system reset and will only energize after
the programmed time delay has expired.
3.3.13.2
ADDRESSABLE RELAY FAN RESTART OPERATION
Each addressable relay module connected to the panel’s SLC loop can be designated for fan restart
operation by configuring it for ‘AHU Shutdown Relay’ operation. Once the relay has been designated for AHU
Shutdown operation, it automatically defaults to a normally energized relay and will activate for any ALARM
event in any of its zones. Like the CRM4 relays, each addressable relay can be configured with a restart
delay (0 – 255 seconds).
Upon activation of an ALARM event, each AHU Shutdown relay will activate and remain active even after the
control panel is reset. After reset, the fan restart sequence must be initiated manually using any of the
following sources: 1) control panel’s “AHU ON” function that can be found in MAINTENANCE MENU 2, 2)
addressable input module configured for “Fan Restart”, 3) peripheral device (i.e., remote display or
input/output card) switch configured for Fan Restart. Once initiated, the panel will start the automatic fan
restart sequence and the AHU Shutdown relays will deactivate according to their programmed time delay
allowing the startup of the AHU fan motors to be staggered.
Note:
Addressable input module or peripheral device (i.e., remote display or input/output card) switches
configured for “Fan Restart” will initiate the fan restart sequence for both panel CRM4 and addressable
relay restart operation.
AHU FIRE KEY
3.3.13.2.1
Activation of the addressable relays for Fan Restart can be further restricted by requiring the activation of an
input module configured for ‘AHU FIRE KEY’ operation before a Fan Restart switch can be acted on by the
panel. This is a system variable that is either enabled or disabled via the panel’s CONFIGURATION MENU 7
> F1-AHUKEY. When enabled, an “AHU FIRE KEY” must be active prior to activation of a Fan Restart switch
in order for the control panel to act upon it. Activation of a Fan Restart switch prior to activation of the ‘AHU
FIRE KEY’ will not start the fan restart sequence. The panel will only indicate the activation of the Fan
Restart switch on its display and the event will be recorded in the panel’s history buffer.
Note:
If fire key operation is used, the switch (key or button operation) must be installed with limited
access and must be UL 864 listed for Fire Protective Signaling System use.
