The SIGA-270 and SIGA-278 series Manual Pull Stations are part of EST’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 powder coat paint complemented by aluminium-coloured stripes and markings.
With the 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) key switch for applications where a two-stage operation is required. The up-front highly visible glass rod discourages tampering but is not required for proper
EST’s double-action single-stage SIGA-278 station is a contemporary style manual station made from durable red-coloured Lexan. To initiate an alarm, first lift the upper door marked “LIFT THEN PULL HANDLE”, then pull the alarm handle.
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.
• Break glass operation
An up-front visible glass rod on the SIGA-270 discourages tampering.
• Intelligent device with an 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.
• Stand-alone operation
The station inputs an alarm even if the loop controller’s polling interrogation stops.
• 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).
The operating characteristics of the fire alarm stations are determined by their sub-type code or “Personality Code”. NORMALLY OPEN ALARM - LATCHING (Personality 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.
Signature Series manual stations are compatible only with EST’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 is 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.
The fire alarm station’s terminal block accepts #18 AWG (0.75mm2) to #12 AWG (2.5mm2) wire sizes. See Signature Loop Controller catalogue sheet for detailed wiring requirement specifications.
1 Refer to Signature Loop Controller manual for maximum wire distance.
