Smoke/heat detector sensors dual pack KIDDE K5CO (model KID-DSR-K5-PL)

Dual pack of KIDDE K5CO smoke and heat detector sensors (model KID-DSR-K5-PL) provides two replacement or spare detection units designed to sense visible smoke and rapid rises in temperature. Each detector combines photoelectric smoke sensing with a heat sensor to detect smouldering fires and fast-developing heat events, enabling earlier notification when integrated into compatible wired alarm systems or used as direct replacements in existing installations. The compact, low-profile housings are engineered for residential and light commercial environments and fit common mounting bases for straightforward swap-in installation.

Advantages

The KIDDE K5CO dual pack offers dual-mode detection in a single unit, improving responsiveness to both smoky, slow-developing fires and rapid heat events. Supplied as a pair, the set reduces downtime by providing immediate spares for maintenance or staged replacement. The detectors are designed for easy mechanical and electrical compatibility with standard wired alarm system bases, simplifying replacement without major rewiring. Durable plastic enclosures resist common household conditions while maintaining clear sensor access for reliable operation.

Suitable for

• Residential homes (bedrooms, hallways, living areas)
• Light commercial premises (offices, small retail, storage rooms)
• Replacement or upgrade of existing wired smoke/heat detector circuits
• Maintenance spare units for property managers and installers

Key specifications

• Detection type: combined photoelectric smoke sensor and rate-of-rise heat sensor
• Number of units: two detectors per pack
• Compatibility: designed for wired alarm system integration and standard mounting bases
• Application environment: indoor residential and light commercial use
• Housing: compact, low-profile plastic enclosure suitable for ceiling or wall mounting

How to use

Before installation, verify compatibility with your existing alarm system and power down the circuit according to the system manufacturer’s instructions. Remove the old detector by twisting or unfastening the mounting base and disconnecting wiring terminals, noting the wiring positions. Connect the wiring to the replacement detector terminals following the original configuration, secure the detector into the mounting base, and restore power. After installation, perform system tests to confirm correct communication with the control panel and proper sensor response to test stimuli as outlined by the alarm system and detector manufacturer.

Usage recommendations

Install detectors on ceilings or high on walls away from drafts, vents, and cooking appliances to reduce false alarms. Test detectors after installation and at regular intervals, replace according to the manufacturer’s service life guidance, and use the spare unit from the pack to minimize downtime during maintenance or replacement of aged detectors.
