GSA-UM Universal Class A/B Module Installation
Sheet
The GSA-UM Universal Class A/B Module is an addressable
module that you can configure to provide one of the following:
•Two Class B dry contact initiating device circuits
•One Class A dry contact initiating device circuit
•One Class A or Class B notification appliance circuit
•One Class A or Class B verified two-wire (conventional)
smoke detector circuit without dry contact initiating devices
on the same circuit
•One Class A or Class B unverified two-wire (conventional)
smoke detector circuit with or without dry contact initiating
devices on the same circuit
•One Form C dry contact relay output
The GSA-UM requires two device addresses on the signaling
line circuit (SLC). Addresses are assigned electronically. There
are no addressing switches.
Diagnostic LEDs provide visible indication of the status of the
module:
•Normal: Green LED flashes
•Alarm/active: Red LED flashes
Personality codes
The module requires the loop controller to download the
personality code that determines how the module operates.
Use the personality codes described below to configure the
GSA-UM. Refer to Table 1 for UL 864 programming
requirements. See
Table 2 for personality code electrical characteristics.

N/A
N/A
Personality code 1: Alarm - NO latching (Class B): Factory
default. Configures input 1 or 2 for Class B, normally open dry
contact initiating devices (e.g., pull stations, heat detectors,
etc.). When the NO input contact of an initiating device is
closed, an alarm signal is sent to the loop controller and the
alarm condition is latched at the module.
Personality code 2: Alarm - NO delayed latching (Class B):
Same as code 1 except that contact closure must be
maintained for approximately 16 seconds before an alarm
signal is sent. This code is only for use with nonretarded
waterflow alarm switches.
Personality code 3: Active - NO nonlatching (Class B):
Contact closure causes an active instead of an alarm status
and does not latch at the module. Code 3 is typically used for
monitoring fans, dampers, and doors.
Personality code 4: Active - NO latching (Class B): Contact
closure causes an active instead of an alarm status, which is
latched at the module. Code 4 is typically used for monitoring
supervisory and tamper switches.
Personality code 8: Signal - dry contact output: Configures
the module as a Form C dry relay contact to control external
appliances (door closers, fans, dampers) or equipment
shutdown. Note: Jumper JP1 must be moved to pins 2 and 3
for dry contact operation.
Personality code 9: Alarm - NO latching (Class A): Configures
the module for connection of Class A, normally open dry
contact initiating devices (e.g., pull stations, heat detectors,
etc.). When the NO input contact of an initiating device is
closed, an alarm signal is sent to the loop controller and the
alarm condition is latched at the module.

2 / 7 P/N P-047550-1816-EN • REV 007 • ISS 21SEP17
Personality Code 10: Alarm - NO delayed latching (Class A):
Same as code 9 except that contact closure must be
maintained for approximately 16 seconds before an alarm
signal is sent. Code 10 is typically used with waterflow alarm
switches.
Personality code 11: Active - NO nonlatching (Class A):
Same as code 9 except that contact closure causes an active
instead of an alarm status, and does not latch at the module.
Personality code 11 is typically used for monitoring fans,
dampers, and doors.
Personality code 12: Active - NO latching (Class A): Same as
code 9 except that contact closure causes an active instead of
an alarm status, which is latched at the module. Code 12 is
typically used for monitoring supervisory and tamper switches.
Personality code 13: Alarm - two-wire smoke unverified
(Class B): Configures the module for monitoring two-wire
conventional smoke detectors (that do not require alarm
verification) and normally open contact initiating devices (e.g.,
pull stations, heat detectors, etc.) on the same circuit.
Personality code 14: Alarm - two-wire smoke verified
(Class B): Configures the module for monitoring two-wire
conventional smoke detectors (that require alarm verification).
Normally open contact initiating devices may not be mixed with
two-wire conventional smoke detectors.
Personality code 15: Signal - supervised output (Class A):
Configures the module for connection of a Class A output
notification appliance circuit (NAC). Code 15 is typically used
to control bells, speakers, etc.
Personality code 16: Signal - supervised output (Class B):
Configures the module for connection of a Class B output
notification appliance circuit (NAC). Code 16 is typically used
to control bells, speakers, etc.
Personality code 20: Alarm - two-wire smoke unverified
(Class A): Same as personality code 13, except that wiring is
Class A.
Personality code 21: Alarm - two-wire smoke verified
(Class A): Same as personality code 14, except that wiring is
Class A.
For personality codes 13, 14, 20 and 21
First SIGA-UM on a loop to go into alarm will maintain the 2
wire detector circuit voltage and current so that the 2 wire
detector can maintain its LED. Second SIGA-UM on the same
loop to get an alarm from a 2 wire detector will indicate the
alarm at the control panel but will reduce voltage and current
on its 2 wire circuit causing the detector LED to turn on and off.

Wiring
Wire in accordance with applicable requirements of the latest
editions of the local codes and standards and the local
authority having jurisdiction.
Note: When stripping wire ends, exposing more wire may
cause a ground fault; exposing less wire may result in a faulty
connection.
Strip 1/4 in. (about 6 mm) from the ends of all wires that
connect to the terminal block of the module.
General wiring notes
•Refer to the Signature loop controller installation sheet for
SLC wiring specifications.
•Each terminal on the module is limited to a single
conductor.
•Only personality codes 13, 14, 20, and 21 support two-
wire smoke detectors.
•Test resistors are supplied with the GSA-UM to prevent
trouble signals on unused circuits during installation.
When connecting field wires, remove the test resistors and
install a UL/ULC Listed 47 kΩEOLR at the end of the
circuit.
Riser notes
•For maximum line impedance, refer to the installation
manual for the fire alarm panel. Maximum circuit
capacitance is 0.1 µF.
•If the riser is used for more than one notification zone,
install in accordance with the survivability from attack by
fire requirements in NFPA 72 National Fire Alarm and
Signaling Code.
Two-wire smoke detector notes
•A maximum of 15 GSA-UM modules per circuit can be
configured to support two-wire smoke detectors
(personality codes 13, 14, 20, and 21). However, if a
Signature Series IM module or Signature Series detector
with an isolator base (IB) is installed on the SLC, only 7
GSA-UM modules may be configured to support two-wire
smoke detectors.
•Use compatible smoke detectors. See the control panel
compatibility list for type and quantity.
•Polarity at terminals is shown in the supervisory condition.
Connect as shown in the diagram. (Polarity reverses on
alarm.)
•IDC wiring is Style B (Class B) or Style D (Class A).
To wire the module:
1. Verify that all field wiring is free of opens, shorts, and
ground faults.
2. Make all wiring connections using the appropriate figure
below for the desired function (personality code).
