Hochiki ESP Addressable Manual Call Point With Short Circuit Isolator
£25.55 (inc VAT: £30.66)
Summary
The Hochiki HCP-E(SCI) is an analogue addressable manual call point featuring an integral short-circuit isolator, designed for use with Hochiki’s ESP analogue addressable protocol. It is suitable for installation in a wide range of commercial and industrial fire detection systems where loop integrity and reliable manual alarm initiation are essential.
The unit incorporates a bi-coloured LED indicator that can be configured for pulsing or non-pulsing operation during communications polling, subject to fire alarm control panel compatibility. The LED displays red when the device is in normal polling or activated states, and switches to amber to indicate the presence of a short-circuit on the loop — reverting to red if the unit is simultaneously activated.
A built-in test function, initiated via the control panel, ensures device integrity at all times. Additional field testing is possible by inserting a test key into the underside of the unit. Two terminal blocks are provided for straightforward connection to loop wiring, and addressing is carried out quickly and reliably using the TCH-B200 Hand Held Programmer.
The HCP-E(SCI) is supplied flush-mountable as standard, with a non-frangible resettable element fitted. For surface mounting applications, the SR MOUNTING BOX is required and sold separately. An optional glass element is also available for installations where this is preferred.

FAQ
What fire detection protocol is the HCP-E(SCI) compatible with?
The HCP-E(SCI) is fully compatible with Hochiki’s ESP analogue addressable protocol, making it suitable for use with ESP-compatible fire alarm control panels.
What is the purpose of the integral short-circuit isolator?
The integral short-circuit isolator (SCI) protects the detection loop by isolating a short-circuit fault, preventing it from disabling other devices on the same loop. The bi-coloured LED will display amber when a short-circuit condition is detected.
How is the HCP-E(SCI) addressed?
The device is addressed using the TCH-B200 Hand Held Programmer, which allows quick and reliable address assignment in the field.
Can the HCP-E(SCI) be surface mounted?
Yes. The unit is supplied flush-mountable as standard. For surface mounting, the SR MOUNTING BOX is required and is available separately.
What type of element does the HCP-E(SCI) use?
A non-frangible resettable element is fitted as standard, conforming to EN54. An optional glass element is also available. If changing from a glass element to a flexi element, the operation must be confirmed by pressing the resettable element.
How can the HCP-E(SCI) be tested?
The device includes a built-in test function that can be initiated from the fire alarm control panel to verify device integrity. It can also be tested manually by inserting a test key into the underside of the unit.
What certifications does the HCP-E(SCI) hold?
The HCP-E(SCI) is LPCB approved to EN54-11 (manual call points) and EN54-17 (short-circuit isolators). A SIL Level 2 approved variant (HCP-E(SCI)/SIL) is also available.
Is a ‘Smoke Vent’ variant available?
Yes, a variant with a ‘SMOKE VENT’ label is available for installations where the manual call point is used to activate smoke ventilation systems.
