Intelligent Control Module
Architect and Engineering Specifications
Intelligent control module shall be a System Sensor model number M500S. Addressable control
modules shall provide supervised monitoring of wiring to load devices that require an external
power supply to operate, such as horns, strobes, or bells. It shall be capable of Class B (Style Y)
and Class A (Style Z) supervision. Upon command from the control panel, the control module
shall be able to disconnect the supervision and connect the external power supply across the
load device. The disconnection of the supervision shall provide verification to the panel that the
control relay state changed. The external power supply shall always be relay isolated from the
communication loop. The control module shall transmit full analog measurement of the
supervised wiring back to the panel and can be used to detect impedance changes or other
special test functions.
The modules shall provide address-setting means on the module using rotary switches. Because
of the possibility of installation error, systems that use binary jumpers or DIP switches to set the
module address are not acceptable. The modules shall also store an internal identifying code
that the control panel shall use to identify the type of detector. Systems that require a special
programmer to set the module address (including temporary connection at the panel) are labor
intensive and not acceptable. Each module occupies any one of at least 99 possible addresses
on the signaling line circuit (SLC) loop. It responds to regular polls from the system and reports
its type and status.
The module shall have an LED that is controlled by the panel to indicate module status. Coded
signals, transmitted from the panel, can cause the LED to blink, latch on, or latch off. Refer to the
control panel technical documentation for module LED status operation.
The module shall mount in a standard 4-inch square, 2-1/8" deep electrical box, surface mounted
backbox listed, or compatible duct smoke detector housing. The notification appliance circuit
(NAC) shall wire in a Class B (Style Y) or Class A (Style Z) fashion. Each control module shall
support up to 1 amp of inductive or 2 amps of resistive audible/visual signals. Audio/visual power
shall be provided by a separate supervised power loop from the main fire alarm control panel or
from a supervised, UL listed remote power supply. The module shall use SEMS screws for easy
wiring. Wiring terminals shall be easily accessible for troubleshooting while installed.
