Example # 1; Example # 2: General Alarm - Honeywell SCS-8 Operation And Installation Manual

Programming Examples

Example # 1

L1D1, L1D2, and L1D3 are first floor smoke detectors that acti-
vate Z1. L1D4 is a first floor elevator lobby smoke detector that
activates Z2. If Z1 activates, control module L1M1 and L1M4
will activate. Control module L1M1 could be used to close the
supply damper to the floor during a fire condition. If Z2 acti-
vates then control module L1M4 will activate. Control module
L1M4 could be used to turn on a fan to pressurize the elevator
shaft. The equation AND(Z1 Z238) requires both to be active for
an output. Because reverse Zone 238 has a NOT operand, it is
active as long as L1D4 is inactive. So if there is smoke on the
floor but not in the elevator lobby, Z239 activates and control
module L1M2 is active.

Example # 2: General Alarm

L1D1 activates L1M1 through Z1. L1D2 activates
L1M2 through Z2. L1D3 and L1D4 activate L1M4
through Z3. L1M3 will activate when reverse zone
239 is activated. Z239 will activate when Z1, Z2 or Z3
are activated.
Notification Appliance L1M3 serves as the General
Alarm device. It will be activated whenever an alarm
occurs on any initiating device in the system, due to
the fact that all initiating devices activate a Software
Zone, and activation of any zone activates software
zone Z239.
