They also mount to European BESA and 1-gang boxes with 60.3 mm fixing centers.The SIGA-SB4, SIGA-RB4, and SIGA-I134 0.8'(20 mm) mount to North American 4 inch sq.electrical boxes in addition to the above boxes.They include the SIGA-TS4 Trim Skirt which is used to cover the"mounting ears"on the base.The SIGA-AB4G 2.0"(51 mm) mounts to a 4"sgare box only. 4.4"012 mm) Tamper-Resist Lever Arm ® SIGA-AB4G/T/LF SIGA-SB SIGA-IB SIGA-RB SIGA-LED -Break off to disable- ® Audible Base Standard Base Isolator Base Relay Base Remote LED (Located on Base) Standard Base SIGA-SB,SIGA-SB4-This is the basic mount- ing base for EDWARDS Signature Series detectors.The SIGA- Access Slot for ' LED Remote LED is supported by the Standard Base. Tamper-Resist Mechanism ` t _ Relay Base SIGA-RB,SIGA-RB4-This base includes a relay. Normally open or closed operation is selected during installation. CD The dry contact is rated for 1 amp(pilot duty)C 30 Vdc.The relay's position is supervised to avoid accidentally jarring it out of position. The SIGA-RB can be operated as a control relay if programmed Testing & Maintenance to do so at the control panel(EST3 V.2 only).The relay base does not support the SIGA-LED Remote LED. Each detector automatically identifies when it is dirty or defective Audible Base SIGA-AB4G -This base is designed for use where and causes a"dirty detector"message.The detector's sensitiv- localized or group alarm signaling is required.When the detector ity measurement can also be transmitted to the loop controller.A senses an alarm condition,the audible base emits a local alarm sensitivity report can be printed to satisfy NFPA sensitivity meas- signal.The optional SIGA-CRR Polarity Reversal Relay can be used urements which must be conducted at the end of the first year for sounding to other audible bases on the same 24 Vdc circuit. and every two years thereafter. Relay and Audible Bases operate as follows: The user-friendly maintenance program shows the current state -at system power-up or reset,the relay is de-energized of each detector and other pertinent messages. Single detectors -when a detector is installed in the base with the power may be turned off temporarily from the control panel.Availability of on,the relay energizes for four seconds,then de-energizes maintenance features is dependent on the fire alarm system used. -when a detector is removed from a base with the power on, Scheduled maintenance(Regular or Selected)for proper detec- the relay is de-energized for operation should be planned to meet the requirements of the Authority Having Jurisdiction(AHJ). Refer to current NFPA 72 and -when the detector enters the alarm state,the relay is energized. ULC CAN/ULC 536 standards. Isolator Base SIGA-IB,SIGA-I134-This base includes a built-in line fault isolator for use on Class A circuits.A detector must be installed for it to operate.The isolator base does not support the Compatibility SIGA-LED Remote LED. The SIGA-PS detectors are compatible only with the Signature The isolator operates as follows: Loop Controller. -a short on the line causes all isolators to open within 23 msec -at 10 msec intervals, beginning on one side of the Class A circuit nearest the loop controller,the isolators close to provide the next isolator down the line with power Warnings & Cautions -when the isolator next to the short closes,reopens within 10 This detector will not operate without electrical power.As fires fre- msec. quently cause power interruption,we suggest you discuss further The process repeats beginning on the other side of the loop safeguards with your fire protection specialist. controller.

SIGA-TS4 Trim Skirt-Supplied with 4 inch bases, it can also be ordered separately to use with the other bases to help hide surface imperfections not covered by the smaller bases.
