General

FCM-1(A) Control Module: The FCM-1(A) Addressable Con-

trol Module provides Notifier intelligent fire alarm control pan-

els a circuit for Notification Appliances (horns, strobes,

speakers, etc.). Addressability allows the FCM-1(A) to be acti-

vated, either manually or through panel programming, on a

select (zone or area of coverage) basis.
FRM-1(A) Relay Module: The FRM-1(A) Addressable Relay

Module provides the system with a dry-contact output for acti-

vating a variety of auxiliary devices, such as fans, dampers,

control equipment, etc. Addressability allows the dry contact to

be activated, either manually or through panel programming,

on a select basis.
FlashScan® (U.S. Patent 5,539,389) is a communication pro-

tocol developed by NOTIFIER Engineering that greatly

enhances the speed of communication between analog intelli-

gent devices. Intelligent devices communicate in a grouped

fashion. If one of the devices within the group has new infor-

mation, the panel CPU stops the group poll and concentrates

on single points. The net effect is response speed greater than

five times that of other designs.

Features

• Built-in type identification automatically identifies these

devices to the control panel.

• Internal circuitry and relay powered directly by two-wire

SLC loop. The FCM-1(A) module requires power (for horns,

strobes, etc.), or audio (for speakers).

• Integral LED “blinks” green each time a communication is

received from the control panel and turns on in steady red

when activated.

• LED blink may be deselected globally (affects all devices).
• High noise immunity (EMF/RFI).
• The FCM-1(A) may be used to switch 24-volt NAC power,

audio (up to 70.7 Vrms).

• Wide viewing angle of LED.
• SEMS screws with clamping plates for wiring ease.
• Direct-dial entry of address 01– 159 for FlashScan loops,

01 – 99 for CLIP mode loops.

• Speaker, and audible/visual applications may be wired for

Class B or A (Style Y or Z).

Applications

The FCM-1(A) is used to switch 24 VDC audible/visual power,

high-level audio (speakers). The FRM-1(A) may be pro-

grammed to operate dry contacts for applications such as door

holders or Air Handling Unit shutdown, and to reset four-wire

smoke detector power.

NOTE: Refer to the SLC Manual (PN 51253) for details regarding
releasing applications with the FCM-1(A). Refer to the FCM-1-REL
datasheet (DN-60390) for new FlashScan® releasing applications.

Construction

• The face plate is made of off-white heat-resistant plastic.
• Controls include two rotary switches for direct-dial entry of

address (01-159).

• The FCM-1(A) is configured for a single Class B (Style Y) or

Class A (Style Z) Notification Appliance Circuit.

• The FRM-1(A) provides two Form-C dry contacts that

switch together.

Operation

Each FCM-1(A) or FRM-1(A) uses one of 159 possible module

addresses on a SLC loop (99 on CLIP loops). It responds to

regular polls from the control panel and reports its type and

status, including the open/normal/short status of its Notifica-

tion Appliance Circuit (NAC). The LED blinks with each poll

received. On command, it activates its internal relay. The

FCM-1(A) supervises Class B (Style Y) or Class A (Style Z)

notification or control circuits.
Upon code command from the panel, the FCM-1(A) will dis-

connect the supervision and connect the external power sup-

ply in the proper polarity across the load device. The

disconnection of the supervision provides a positive indication

to the panel that the control relay actually turned ON. The

external power supply is always relay isolated from the com-

munication loop so that a trouble condition on the external

power supply will never interfere with the rest of the system.
Rotary switches set a unique address for each module. The

address may be set before or after mounting. The built-in

TYPE CODE (not settable) will identify the module to the con-

trol panel, so as to differentiate between a module and a sen-

sor address.

Specifications for FCM-1(A)

Normal operating voltage: 15 to 32 VDC.
Maximum current draw: 6.5 mA (LED on).
Average operating current: 350 μA direct poll, 375 μA group

poll with LED flashing, 485 μA Max. (LED flashing, NAC

shorted.)
