Step 4. Setting
Use the following guidelines when setting these values:
Timer Options
• Manual Release. The Manual Release Time Delay is a programmable timer that specifies
the delay between the activation of a manual release switch and the activation of releasing
appliances. The default setting for this timer is 10 seconds. A setting of 0 causes the
releasing appliances to immediately activate after a manual release switch activates. This
delay is programmable from 0-30 seconds.
• Detector Release Delay. The Automatic Release Time Delay is a programmable timer that
delays the activation of the releasing appliance circuits. This timer starts immediately after
receiving a confirming alarm (cross zoned system) or a first alarm (single alarm system).
When the timer expires, the releasing appliances activate (assuming the abort switch is not
active). This delay is programmable from 0-60 seconds.This delay makes evacuation of the
protected space possible before the agent is released. Consider a delay timer when occupants
could be present in the protected space.
• Releasing Cutout. The Releasing Cutout Timer is a programmable timer that specifies the
length of time the output on the Suppression Release Peripheral is held on. When the timer
expires, the solenoid turns off (or cuts out), which stops the water flow or release of the
extinguishing agent. This option is typically used on Deluge systems and is not intended for
use with all releasing systems and releasing devices. A selection of "0" means the solenoid
does not "cut out" and remains on until the system is reset. The Countdown Timer is
programmable from 0-30 minutes.
Step 5. Specifying The next screen, shown in Figure 9-34, contains seven buttons, each corresponding to one of
the suppression-release system lists. Points are automatically assigned to the appropriate list
Hazard Area
based on the suppression release point type assigned to the point.

• Cross-Zoned System. The occupants receive a warning signal of the first alarm and
receive an evacuation signal on the second alarm. Implementing a warning signal
makes it possible to investigate the alarm before the second (confirmed) alarm.
Implementing a delay on the second alarm gives time for occupants to evacuate, and
where required, for the ventilation fans and dampers to shut down prior to the release
activation.
• Single Alarm System. A selection of "0" seconds activates the releasing circuit at the
same time as when the NACs signal an initial warning. A delay provides time for
occupants to evacuate, and where required, for the ventilation fans and dampers to shut
down prior to the release activation.
