APPENDIX - L: RELEASING OPERATION
Configure:
•
Set up a countdown time for the releasing operation to start when the releasing control
condition is satisfied.
•
Set up the activation time for the NAC/Output channel:
ReleaseSync: operate simultaneously with the releasing channel.
Immediately: operate once the releasing control condition is satisfied.
•
When the releasing control condition is satisfied, the countdown time starts. When the
countdown time is over, the releasing operation starts to distinguish the fire.
Manual releasing:
•
When the releasing control is in pre-discharge phase, the releasing circuit is activated
immediately when the corresponding manual release is triggered.
•
When the releasing control is not in the pre-discharge phase, a countdown timer of the
releasing circuit starts when the corresponding manual release is triggered. The
countdown time can be customized and the range is 10
… 60 s. UL allows up to 30
seconds.

immediately when the abort is deactivated.

Physical Disconnect Switch
Releasing service fire alarm systems used for fire suppression-releasing service (non-water
based) shall have the capability to disconnect releasing circuit(s).
A Listed physical disconnect switch (such as Fike model 10-2705) shall be used.
To provide a separate releasing notification, Audible Base (ABHW) needs to be installed
and programmed to sound March tone during pre-discharge, and a different tone (e.g.
continuous tone) when it discharges.
For Canadian Releasing applications the AW-3B self-restoring abort switch must be used.
It is painted blue and contains French Canadian verbiage.
For Canadian Releasing applications, the MSM-RB non-self-restoring manual release
switch must be used. It is painted yellow and contains French Canadian verbiage.
