SIGA-270 SERIES
Overview
The SIGA-270 and SIGA-278 series Manual Pull Stations are part
of EDWARDS’s Signature Series system. The SIGA-270 Fire Alarm
Manual Pull Stations feature our very familiar teardrop shape. They
are made from die-cast zinc and finished with red epoxy powdercoat paint complemented by aluminum colored stripes and markings. With positive pull-lever operation, one pull on the station
handle breaks the glass rod and turns in a positive alarm, ensuring
protection plus fool-proof operation. Presignal models (SIGA-270P)
are equipped with a general alarm (GA) keyswitch for applications
where two stage operation is required. The up-front highly visible
glass rod discourages tampering, but is not required for proper
operation.
EDWARDS’s double action single stage SIGA-278 station is a
contemporary style manual station made from durable red colored
lexan. To initiate an alarm, first lift the upper door marked “LIFT
THEN PULL HANDLE”, then pull the alarm handle.
Standard Features
Note: Some features described here may not be supported by all control systems. Check your control panel’s Installation and Operation Guide for details.
• Traditional familiar appearance
SIGA-270 models feature our familiar teardrop design with
simple positive pull action and sturdy die-cast metal body.
• One stage (GA), two stage (pre-signal), and double action
models
SIGA-270 models are available for one or two stage alarm
systems. The single stage double action SIGA-278 features a
rugged Lexan housing with keyed reset mechanism.
SIGA-278
• Break glass operation
An up-front visible glass rod on the SIGA-270 discourages
tampering.
• Intelligent device with integral microprocessor
All decisions are made at the station allowing lower communication speed while substantially improving control panel
response time. Less sensitive to line noise and loop wiring
properties; twisted or shielded wire is not required.
• ADA Compliant
Meets ADA requirements for manual pull stations.
• Electronic Addressing with Non-volatile memory
Permanently stores programmable address, serial number,
type of device, and job number. Automatically updates historic
information including hours of operation, last maintenance
date, number of alarms and troubles, and time and date of last
alarm.
• Automatic device mapping
Each station transmits wiring information to the loop controller regarding its location with respect to other devices on the
circuit.
• Diagnostic LEDs
Status LEDs; flashing GREEN shows normal polling; flashing
RED shows alarm state.
• Designed for high ambient temperature operation
Install in ambient temperatures up to 120 °F (49 °C).

Application
The operating characteristics of the fire alarm stations are determined by their sub-type code or “Personality Code”. NORMALLYOPEN ALARM - LATCHING (Pesonality Code 1) is assigned by the
factory; no user configuration is required. The device is configured
for Class B IDC operation. An ALARM signal is sent to the loop
controller when the station’s pull lever is operated. The alarm condition is latched at the station.
Compatibility
Signature Series manual stations are compatible only with EDWARDS’s Signature Loop Controller.
Warnings & Cautions
This device will not operate without electrical power. As fires frequently cause power interruption, we suggest you discuss further
safeguards with your local fire protection specialist.
Testing & Maintenance
To test (or reset) the station simply open the station and operate
the exposed switch. The SIGA-270 series are opened with a tool;
the SIGA-278 requires the key which is supplied with that station.
The station’s automatic self-diagnosis identifies when it is defective and causes a trouble message. The user-friendly maintenance
program shows the current state of each Signature series device
and other pertinent messages. Single devices may be deactivated
temporarily, from the control panel. Availability of maintenance
features is dependent on the fire alarm system used.
Scheduled maintenance (Regular or Selected) for proper system
operation should be planned to meet the requirements of the
Authority Having Jurisdiction (AHJ). Refer to current NFPA 72 and
ULC CAN/ULC 536 standards.
Typical Wiring
The fire alarm station’s terminal block accepts #18 AWG (0.75mm2)
to #12 AWG (2.5mm2) wire sizes. See Signature Loop Controller
catalog sheet for detailed wiring requirement specifications.
Wiring Notes
1 Refer to Signature Loop Controller manual for maximum
wire distance.
2. All wiring is power limited and supervised.

Single-stage Signature Series fire alarm manual pull stations mount to North American 2½ inch (64 mm) deep 1-gang boxes.
Two stage presignal (270P) models require 1½ inch (38 mm) deep 4-inch square boxes with 1-gang, ½-inch raised covers. Openings
must be angular. Rounded openings are not acceptable. Recommended box: Steel City Model 52-C-13; in Canada, use Iberville Model CI52-C-49-1/2.
All models include terminals are suited for #12 to #18 AWG (2.5 mm2 to 0.75 mm2) wire size. EDWARDS recommends that these fire
alarm stations be installed according to latest recognized edition of national and local fire alarm codes.
Electronic Addressing: The loop controller electronically addresses each manual station, saving valuable time during system com-
missioning. Setting complicated switches or dials is not required. Each station has its own unique serial number stored in its on-board
memory. The loop controller identifies each device on the loop and assigns a “soft” address to each serial number. If desired, the stations
can be addressed using the SIGA-PRO Signature Program/Service Tool.
